Laser vision correction has transformed the way individuals achieve clear vision without relying on glasses or contact lenses. Two procedures, LASIK (Laser-Assisted In Situ Keratomileusis) and SMILE (Small Incision Lenticule Extraction), offer distinct advantages based on your unique vision needs and eye conditions.
Understanding LASIK vs SMILE
LASIK: The Gold Standard
LASIK involves creating a thin corneal flap using a laser or microkeratome. After lifting the flap, another laser reshapes the underlying corneal tissue to correct refractive errors such as myopia, hyperopia, and astigmatism. This method is highly precise and has a long track record of safety and efficacy.
SMILE
SMILE uses a femtosecond laser to create a small lenticule (a disc-shaped piece of corneal tissue) within the cornea. This lenticule is removed through a small incision, reshaping the cornea and correcting vision.
SMILE vs. LASIK: A Quick Comparison
As you weigh your options for vision correction surgery, consider these key differences between SMILE and LASIK:
SMILE vs LASIK: Research Support
According to the Cleveland Clinic:
LASIK: Studies say that about 99% of people have uncorrected vision that’s 20/40 or better after having LASIK surgery. More than 90% of people end up with 20/20 vision. More than 7,000 research studies have confirmed LASIK is a safe surgery.
SMILE: Research thus far has shown SMILE to be about as effective as LASIK. For example, one study of people who had SMILE surgery found that 99% of them had at least 20/40 vision six months after the surgery. The same study showed that 88% had 20/20 vision at their six-month check-up.
Choosing Between LASIK and SMILE:
Corneal Thickness: If you have a thinner cornea, SMILE may be a safer option.
Flap Creation Preference: Some individuals may prefer the absence of a corneal flap, making SMILE a suitable choice.
Quick Recovery: If rapid visual recovery is crucial, LASIK may be preferred.
Both LASIK and SMILE are effective refractive surgery options, and the choice between them depends on individual factors, patient preferences, and the surgeon’s recommendation. Consulting with an experienced ophthalmologist is crucial to determine the most suitable procedure based on your unique needs and circumstances.

If you suffer from vision problems, you have probably longed for the ability to see without the aid of glasses or contacts. To wake up and get out of bed without reaching for your glasses, to see the alarm clock without squinting, to go for a run without glasses slipping down your nose—this would be a dream come true! You may have read about LASIK surgery and have even practiced the scenario in your mind about qualifying for LASIK. Afterall, it can reduce your dependence on glasses and contacts and finally bring the freedom that you have been envisioning! But if you’re considering any surgery, including LASIK eye surgery, you will naturally wonder if the procedure is safe for you.
Is LASIK Safe?
What is LASIK eye surgery?
LASIK is a two-step surgical procedure that can be used to treat nearsightedness, farsightedness, and astigmatism. The first step in the procedure is for the LASIK surgeon to make a small flap in the cornea (the outermost clear covering of an eye). This can be done using a blade or a laser, depending on the surgeon’s preferred surgical technique. For the second step, the surgeon will gently lift the flap to allow a different laser to reshape the cornea to the exact specifications of that patient’s eye prescription. Then, the corneal flap will be laid back into place, and the healing will begin.
Is LASIK surgery risky?
With any surgery, there exists the possibility of experiencing certain side effects or complications. Some of the possible complications of LASIK include inflammation or infection, issues with the corneal flap and dry eyes. However, LASIK has been approved by FDA since 1999 and has an impressive track record for effectiveness and safety – both of which contributes to LASIK’s sustained popularity.
In fact, LASIK is one of the most well studied elective surgeries performed today. Recent clinical data estimates a patient satisfaction rate of greater than 96%, which also demonstrates the safety standard of LASIK procedures. Research also estimates the rate of truly significant complications from LASIK eye surgery at less than 1 percent, making LASIK one of the safest elective procedures performed today.[i]
What are the potential side effects of LASIK surgery?
Possible side effects that LASIK patients may experience include:
Undercorrection/Overcorrection: This occurs when overall laser tissue removal is less than intended (undercorrection) or more than intended (overcorrection), because of one’s own unique biological characteristics. One of the clinician reasons are under- or over-response by the corneal tissues to the planned laser treatment. Regardless of the exact reasons involved, most patients will require only a minor laser touch up (LASIK enhancement) after having healed from the first laser treatment.
Haloes, glare, and issues with night vision: Some of the more common side effects that your LASIK specialist will advise you of include seeing haloes (rings of light), glare from light, or having difficulty seeing at night. When these do occur in patients, they typically resolve on their own in days to weeks.
Dry eyes: Although not all patients are symptomatic, we do expect patients to experience temporary dry eyes after LASIK. This also typically resolves itself within the first year, and it can be treated using eye drops in the meantime. Fortunately, 93% of patients report to not have dry eye symptoms or have returned to their baseline comfort at 12 months[ii]
Can you go blind from LASIK?
People often cite the fear of going completely blind as a concern when considering LASIK. While it is natural to be protective about your vision, there has never actually been a reported patient case where LASIK eye surgery was the primary cause of total blindness.[iii]
Will I need to have repeated LASIK procedures?
A common misconception is that LASIK “wears off” and a patient will need to keep having LASIK procedures every few years in order to maintain the original laser vision correction effects. However, this is not the case. Once LASIK corrects your vision by reshaping tissue underneath the corneal flap, this new tissue shape under corneal flap is permanently maintained under normal physiological situations.
However, like all living things, your own prescription requirements may change over time. For example, all patients will enter a life stage when they need computer or reading glasses (presbyopia), which mislead patients into thinking that LASIK effects have “worn off”. Additionally, patients’ own nearsightedness or farsightedness can naturally progress on its own after LAISK. Fortunately, your eyes may change, but your distance prescription needs don’t generally degrade back to where they were prior to LASIK. In these situations, a new consultation exam with your LASIK specialists can help you figure out if LASIK enhancement can help you.[iv]

Astigmatism is one of the most common vision afflictions, but many people still don’t know exactly what it means. If you are wondering if your blurred vision is a result of this condition, it’s important that you pay a visit to your eye doctor. Below, we’ve outlined some basic information to help you understand what astigmatism is, how it can be diagnosed and what LASIK treatments are available for you.
What is astigmatism?
According to the American Academy of Ophthalmology, astigmatism is an “imperfection in the curvature of your eye.” This means that the curvature of the front surface of one eye, known as the cornea, is different from the shape of the cornea in the other eye. A healthy cornea is smooth in all directions, but those with astigmatism may have corneas that are irregularly shaped, resulting in blurred vision. Unlike nearsightedness or farsightedness, astigmatism blurs eyesight at all distances.
Optometrists have a number of tools they can use to diagnose astigmatism. This is usually done during a comprehensive eye exam, which is why it’s important to visit your eye doctor at least once a year. During the test, your optometrist may carry out a visual acuity screening, and he or she may use what’s known as a keratometer to measure the curvature of your cornea. Finally, your doctor will use a tool called a phoropter, which involves putting several lenses in front of your eyes, to see how you are able to focus light.
Can LASIK Fix An Astigmatism?
Dr. Dinga shares his thoughts on LASIK eye surgery & Astigmatism
Fortunately, astigmatism is a highly treatable condition. Eyeglasses and contact lenses can offer a solution. Others may prefer to undergo LASIK vision correction. A custom LASIK procedure can reshape the cornea, smoothing out the surface and restoring some or all of your vision. If you’re interested in corrective laser eye surgery, bring it up with your doctor during your next visit. He or she will be able to evaluate your eyes to see if you are a strong candidate for the procedure.
LASIK eye surgery has gained significant popularity due to its patient-friendly approach in several key areas. Notably, the LASIK procedure itself is swift, typically taking around 15 minutes for both eyes. Additionally, the healing process is often rapid and characterized by minimal discomfort. Patients can anticipate noticeable visual improvements shortly after the procedure, enabling them to resume most of their preferred activities. While LASIK boasts a high degree of consistency in outcomes, it’s essential to acknowledge a few remaining questions such as is LASIK eye surgery painful?
Will Your LASIK Eye Surgery Be Painful? Nope! Here’s Why
If you’re worried if LASIK eye surgery is painful. Fear not! The goal of LASIK is to gently reshape the cornea, treating only very, very small portions of tissue, by using a precise laser. Throughout the process, your LASIK surgeon will also take every step to ensure that you are comfortable.
Local Anesthetic – Before your LASIK eye surgery begins, your LASIK specialist will use eye drops to numb the surface of your eyes. These eye drops feel just like the type that you’d normally use to lubricate dry eyes, but contain a numbing agent so that you shouldn’t feel anything, except some pressure, during your LASIK procedure.
No Sedation – With LASIK, you don’t have to worry about heavy sedatives, receiving injections of anesthetics, or “going to sleep” during the procedure. Those eye drops really do all of the numbing that you need, and the lack of heavy general anesthesia means you don’t have to worry about that foggy, groggy feeling after your LASIK surgery is complete.
During LASIK Surgery – During surgery, the first step is creating the flap. You may feel a pressure sensation, but it is more of an odd or uncomfortable feeling than a painful one. Your eyelids will be held open with a special tool during the procedure, and while this may feel a little strange it is unlikely to cause any pain.
Excimer Laser – The cool beam of the excimer laser used to perform LASIK eye surgery is incredibly precise, and guided by a computer which maps the structure of your eyes down to a microscopic level. During the portion of LASIK when your cornea is being reshaped, you actually shouldn’t feel any discomfort at all.
After your LASIK eye surgery is complete, you may notice some minor pain, itching, or discomfort as your eyes heal and your vision stabilizes. These symptoms are common, and typically clear up quickly as your eyes go through the healing process. So while no surgery can truly claim to be completely pain-free, LASIK surgery is about as close as it gets – both during and after your procedure.
Understanding the LASIK Procedure
To better understand why LASIK is not painful, it is important to grasp how the surgery works. LASIK involves reshaping the cornea using a precise laser, targeting very small portions of tissue. Throughout the process, the LASIK surgeon takes every step to ensure patient comfort.
Local Anesthetic and No Sedation
One key aspect of LASIK’s minimal pain is the use of local anesthetic eye drops, which numb the surface of the eyes. These drops eliminate pain during the procedure, and the absence of sedation means patients won’t experience grogginess or a foggy feeling afterward.
Sensations During LASIK Surgery
During the surgery, patients may feel some pressure and discomfort, but not pain. The eyelids are held open with a special tool, which might feel strange but is not painful. The excimer laser used in LASIK is cool, precise, and guided by a computer, ensuring no discomfort during the cornea reshaping process.
Post-Surgery Symptoms and Recovery
After LASIK surgery, it is common to experience minor pain, itching, or discomfort as the eyes heal and vision stabilizes. These symptoms typically clear up quickly, making LASIK one of the least painful surgical procedures available.
How does LASIK feel?
During the LASIK procedure, patients may feel some pressure and discomfort, but not pain. Before the surgery, the LASIK surgeon will use eye drops to numb the surface of the eyes. These eye drops contain a numbing agent that eliminates pain during the procedure, and the absence of sedation means patients won’t experience grogginess or a foggy feeling afterward.
During the surgery, the first step is creating the flap. You may feel a pressure sensation, but it is more of an odd or uncomfortable feeling than a painful one. Your eyelids will be held open with a special tool during the procedure, and while this may feel a little strange it is unlikely to cause any pain. The excimer laser used in LASIK is cool, precise, and guided by a computer, ensuring no discomfort during the cornea reshaping process.
Does LASIK hurt after the procedure?
After LASIK surgery, it is common to experience minor pain, itching, or discomfort as the eyes heal and vision stabilizes. However, these symptoms are typically short-lived and clear up quickly as the eyes go through the healing process. Some patients may experience dry eyes or blurred vision for a few days or weeks after the procedure, but these symptoms can usually be managed with eye drops and will gradually improve over time.
It is important to note that while LASIK is generally a safe and effective procedure, like any surgery, it does carry some risks. Complications such as infection, inflammation, or problems with the flap can occur, but these are rare and can usually be treated with medication or additional surgery if needed.
In conclusion, LASIK eye surgery is a highly desirable option for vision correction due to its minimally invasive nature, use of local anesthetic, and quick recovery time. While no surgery can be entirely pain-free, LASIK comes close. Patients may feel some pressure and discomfort during the procedure, but not pain. After the surgery, it is common to experience minor pain, itching, or discomfort as the eyes heal and vision stabilizes. However, these symptoms are usually short-lived and can be managed with eye drops. If you are considering LASIK, it is important to discuss any concerns or questions you may have with your LASIK surgeon.
The Healing Process After Your LASIK Procedure
When it comes to the healing process after LASIK, there are some important steps you can take to ensure a smooth and comfortable recovery. Your LASIK surgeon will provide detailed instructions on post-operative care, but here are some general tips to keep in mind:
Rest and Relaxation: After the procedure, it is important to rest your eyes as much as possible. You may need to take a few days off work to allow your eyes to recover fully.
Avoid Rubbing Your Eyes: Rubbing your eyes after LASIK can increase the risk of infection and may cause discomfort. It is important to avoid rubbing your eyes for several weeks after the procedure.
Use Eye Drops: Your LASIK surgeon will likely prescribe eye drops to use after the procedure. These drops help to reduce inflammation, prevent infection, and keep your eyes moisturized. It is important to use the drops as directed to ensure proper healing.
Wear Protective Eyewear: After LASIK, it is important to wear sunglasses or other protective eyewear when outside to protect your eyes from UV radiation and other irritants.
Attend Follow-up Appointments: Your LASIK surgeon will schedule follow-up appointments to monitor your healing progress and ensure that you are recovering properly. It is important to attend these appointments to catch any potential complications early on.
In addition to these tips, it is also important to follow a healthy lifestyle to promote healing after LASIK. This includes eating a balanced diet, getting enough rest, and avoiding smoking and excessive alcohol consumption.
Frequently asked questions on the LASIK Procedure:

LASIK (Laser-Assisted In Situ Keratomileusis) surgery has revolutionized the field of ophthalmology, providing millions of people worldwide with a life-changing solution to refractive errors like myopia, hyperopia, and astigmatism. One of the key factors behind the success of LASIK is the continuous evolution of technology, and two significant innovations that have emerged are the Wavelight laser and Contoura Vision. In this article, we dive into the intricacies of LASIK technology, exploring the principles behind the Wavelight laser and the revolutionary Contoura Vision system.
Understanding LASIK Technology
LASIK is a surgical procedure that reshapes the cornea, the transparent front part of the eye, to improve vision by focusing light directly onto the retina. The fundamental concept involves using a laser to create a precise flap on the cornea, followed by the application of another laser to sculpt the corneal tissue and correct refractive errors.
What is the Wavelight LASIK Laser?
Wavelight lasers represent a significant leap forward in LASIK technology. These lasers utilize a sophisticated method called wavefront-optimized technology. Traditional LASIK procedures corrected refractive errors based on prescription glasses, which addressed only the most basic aspects of vision. In contrast, wavefront optimized treatments attempt to preserve the asphericity of the cornea by delivering more laser energy in the corneal periphery.Wavefront optimized treatments reduce or minimize the induction of higher-order aberrations (HOA) that have been associated with visual symptoms after conventional refractive surgery.
What is a Contoura Vision System?
Contoura Vision is a revolutionary LASIK technology that takes personalization to the next level. Developed by Alcon, the Contoura Vision system integrates corneal topography and wavefront-guided technology to create an even more detailed and individualized treatment plan.
Corneal topography involves mapping the curvature of the cornea, providing information about its shape and irregularities. Combining this data with wavefront measurements, the Contoura Vision system creates a comprehensive 3D map of the eye. This precise mapping allows the laser to address not only the refractive errors but also subtle corneal irregularities, known as higher-order aberrations, that were previously difficult to correct.
The Contoura Vision system’s ability to address these higher-order aberrations contributes to improved visual outcomes, particularly in low-light conditions and situations with high contrast. Patients often report sharper, clearer vision and reduced instances of halos and glare.
Comparing LASIK Eye Surgery Technology
Femtosecond Lasers:
IntraLase iFS (now part of Johnson & Johnson Vision): IntraLase iFS is a femtosecond laser system used for creating corneal flaps. It offers high precision and customization, contributing to improved safety and efficacy.
Alcon FS200 the FS200 is another femtosecond laser system used for creating corneal flaps. It offers high precision and customization utilizing a low pulse energy resulting in more precise corneal flaps.
Zeiss VisuMax: Known for its precision, the VisuMax femtosecond laser is often used for creating the corneal flap in LASIK surgery. It operates with extremely short pulses of laser light, allowing for a bladeless and precise corneal flap creation.
Excimer Lasers:

Let’s explore the distinctions between the Wavelight and Visx lasers in LASIK procedures:
Wavefront Technology:
Wavelight: The Wavelight laser, as mentioned earlier, often incorporates wavefront-optimized technology wavefront optimized treatments attempt to preserve the asphericity of the cornea by delivering more laser energy in the corneal periphery to reduce higher order aberrations.
Visx: Visx lasers utilizes either a “standard” or wavefront-guided technology to customize the LASIK procedure based on the patient’s unique visual aberrations. The wavefront technology in Visx systems aims to improve not only basic refractive errors but also higher-order aberrations for enhanced visual outcomes.
Eye Tracking Systems:
Wavelight: Wavelight lasers typically come equipped with advanced eye-tracking systems. These systems monitor the eye’s movements during the procedure and adjust the laser in real-time to ensure accurate and consistent treatment, even if the eye moves slightly.
Visx: Visx lasers also incorporate sophisticated eye-tracking technology to follow the eye’s movements and maintain precision during the LASIK surgery. The accuracy of the eye-tracking system is crucial for achieving optimal results.
Treatment Speed:
Wavelight: Wavelight lasers are known for their fast treatment times. The high-speed laser ablation allows for reduced exposure time and minimizes the potential for dehydration or other factors that could affect the cornea during the procedure.
Visx: Visx lasers are also designed to provide efficient and quick treatments. The speed of the laser ablation process contributes to patient comfort and reduces the overall duration of the LASIK procedure.

Monovision LASIK, a specialized laser corrective procedure, aids individuals dealing with presbyopia. Presbyopia, an age-related hurdle affecting individuals over 40, complicates the focus on nearby objects within arm’s reach.
Beyond presbyopia, Monovision LASIK extends its solutions to a range of visual challenges such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Multiple corrective procedures include:
LASIK: A safe, and effective laser eye surgery capable of addressing a wide array of vision issues, including monovision.
PRK: Similar to LASIK but an alternative option suitable for those with thin corneas or specific eye conditions hindering LASIK eligibility.
During the monovision procedure, one of your eyes will be corrected for clear distance vision and the other eye will be corrected for clear near vision. For most monovision patients, the brain quickly adapts, without any conscious effort by the patient. If monovision is an option for you, the doctor will provide you with additional details during your exam.
What Are The Benefits of Monovision?
Picture a life without having to rely on glasses, and even bidding far-well to contacts! This procedure could pave the way to enhanced confidence and a livelier lifestyle. Yet, just like any procedure, there are a few potential risks that include: dry eyes, glare, or halos.

When it comes to addressing your vision issues, making an informed decision that best suits your needs and eye health is crucial. You may have come across a relatively recent eye surgery known as EVO ICL, which serves as an alternative to LASIK. In this article, we will provide a clear definition of both procedures and discuss their differences to empower you in making the optimal choice for your vision.
What is EVO ICL?
EVO ICL surgery represents a form of refractive surgery that can be likened to the introduction of specialized permanent “contact” lenses into your eyes. These lenses, referred to as Implantable Collamer Lenses (ICL), possess dimensions that are thinner and smaller compared to typical contact lenses. A skilled ophthalmologist implants this lens within the interior of the eye, positioning it behind the iris and in front of the eye’s natural lens. Within the core of the ICL lies a perforation designed to facilitate fluid circulation around the lens and iris. Notably, this lens is permanent and does not necessitate removal or cleaning akin to regular contact lenses.
LASIK VS EVO ICL?
In contrast to EVO ICL surgery, which entails an incision in the eye for lens placement behind the iris, LASIK operates entirely on the cornea, the transparent, front part of the eye. LASIK achieves vision correction by reshaping the cornea, altering its curvature to provide improved vision. Before commencing the LASIK procedure, numbing drops with anesthetic properties are applied to your eyes. Once your eyes are fully anesthetized, a LASIK surgeon employs a laser to create a thin, hinged corneal flap, which is then gently folded back to expose the stromal layer of the cornea. Subsequently, a computer-controlled laser emits controlled pulses of light to reshape the cornea, customizing the correction to your individual visual needs. The corneal flap is repositioned over the treated cornea and begins healing immediately. It adheres through natural suction, eliminating the need for sutures. The precise lasers employed during LASIK procedures ensure the permanent reshaping of the cornea to rectify the patient’s vision.
Risks Associated with EVO ICL
STAAR Surgical, a leading manufacturer of ICL implants, reports the following risks associated with EVO ICL lenses:
1. Additional (Secondary) Surgery
Patients who undergo EVO ICL surgery may find themselves facing the possibility of additional surgeries. These procedures might be necessary for various reasons, such as the need to remove, replace, or reposition the EVO ICL lens. Additionally, secondary surgery could be required if a patient develops a cataract or experiences elevated intraocular pressure. In certain situations, these secondary surgeries are essential for maintaining eye health and visual clarity.
2. Raised Intraocular Pressure (IOP) and Glaucoma Development
Another reported risk associated with EVO ICL surgery is the potential for elevated intraocular pressure (IOP). Normal eye pressure, also known as intraocular pressure (IOP), typically falls within the range of 10-21 millimeters of mercury (mmHg). An IOP above this range is termed ocular hypertension, and if left untreated, it can lead to optic nerve damage, resulting in glaucoma and permanent vision loss. Patients with high levels of nearsightedness are at an increased risk of developing glaucoma. Monitoring and managing IOP is crucial for long-term eye health.
3. Cataract Formation
EVO ICL lenses are implanted inside the eye near the crystalline lens. This proximity increases the risk of cataract development, particularly in older patients with higher levels of nearsightedness prior to surgery. The risk of cataract formation continues to rise with each year the EVO ICL lens remains in the eye. Cataracts that affect vision may necessitate surgical removal. Therefore, regular eye examinations are essential to monitor cataract progression. In cases where cataract surgery is recommended, both the EVO ICL lens and the cataract are addressed simultaneously.
4. Loss of Best Corrected Vision
There is a possibility that your vision may worsen after EVO ICL surgery, resulting in a loss of two or more lines as measured on an eye chart.
5. Endothelial Cell Loss
The cornea’s clarity is maintained by a thin layer of cells called endothelial cells, which pump water out of the cornea. Over time, these cells naturally decrease in number with age. However, EVO ICL surgery can lead to additional loss of these cells beyond the normal rate. Excessive loss can cloud the cornea, reducing vision. Before undergoing EVO ICL surgery, patients receive an eye exam to determine their candidacy. Those implanted with EVO ICL lenses may experience ongoing endothelial cell loss, potentially leading to corneal edema (swelling) or even requiring corneal transplantation.
6. Glare and Halos
Glare and halos, particularly noticeable in low-light conditions with dilated pupils, may become more bothersome after EVO ICL surgery. Even if patients did not experience glare and halos before surgery, they may develop these visual disturbances post-surgery. Patients currently experiencing glare and halos should be aware that these symptoms could intensify following EVO ICL surgery.
7. Additional Risks
Beyond the aforementioned risks, STAAR Surgical also notes that EVO ICL surgery may be associated with additional potential complications, including:
– Movement of the colored portion of the eye (iris) through a surgical wound to a position outside the eye (iris prolapse).
– Bleeding in the area of the retina responsible for reading vision (macular hemorrhage).
– Bleeding beneath the retina (subretinal hemorrhage).
– Increase in focusing error (astigmatism).
– Lifting or pulling of the retina from its natural position (retinal detachment).
– Inability of fluid to flow from the back chamber of the eye to the front chamber, frequently blocking drainage and raising eye pressure (pupillary block glaucoma).
– Unequal pupil size (anisocoria).
– Abnormal release of pigment particles from cells in the eye that could block fluid drainage from inside to outside the eye (pigment dispersion).
– Scar tissue formation at the outer edges of the front chamber of the eye (peripheral anterior synechiae).
EVO ICL surgery offers significant benefits in terms of vision correction, but it is important to be aware of the associated risks. Patients considering this procedure should engage in thorough discussions regarding the risks and benefits with their eye care professionals to make informed decisions about their eye health. Regular post-operative check-ups are vital for monitoring potential complications and addressing them promptly, ensuring the best possible visual outcomes after EVO ICL surgery.
Similarly, LASIK offers significant benefits in terms of vision correction, but like all medical procedures, also presents its own set of associated risks. These may include dry eyes, glare, halos, and the potential need for enhancement surgeries. To determine the most appropriate treatment for your specific needs, you can begin with a LASIK consultation conducted by a qualified LASIK specialist.
At the LASIK Vision Institute, we offer complimentary consultations to assess your eligibility for LASIK. If you qualify, we are excited to provide you with the opportunity to undergo traditional LASIK, which can enhance your vision.
