Everything You Need to Know About LASIK Eye Surgery


Are you tired of depending on glasses or contact lenses to see the world clearly? Discover how LASIK eye surgery can be a great way to get spectacle-free vision. This detailed guide will dive into the benefits of LASIK treatment, the recovery process, post-operative care, and tips for optimizing your eye health.

What is LASIK Eye Surgery?

When a person has normal vision, the cornea (the clear front surface of the eye) effectively bends or refracts light to focus precisely on the retina at the back of the eye. However, in nearsightedness (myopia), farsightedness (hyperopia), or astigmatism, the cornea doesn’t bend the light correctly, resulting in blurry vision.

While glasses and contact lenses can address these vision issues by providing the necessary corrective refraction, an alternative approach is reshaping the cornea itself. By modifying the shape of the cornea, we can achieve the desired refractive changes to restore clear vision.

LASIK eye surgery,  or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that uses a laser to reshape the cornea. It’s a popular option for those who want to reduce their dependence on glasses or contact lenses.

How does LASIK treatment work?

During LASIK eye surgery,  the opthalmologist (eye surgeon) uses a laser to create a thin flap on the cornea. The flap is lifted, and the underlying corneal tissue is reshaped using an excimer laser (an ultraviolet laser). This reshaping allows light to focus correctly on the retina, improving vision.

1. Traditional LASIK:

This is the most common type, where a small blade ( a microkeratome) is used to create the corneal flap before reshaping the cornea with a laser. It’s suitable for mild to moderate vision problems.

2. Bladeless LASIK:

Also known as “All-Laser LASIK,” this method uses a femtosecond laser to create the corneal flap instead of a blade. The reshaping is then done using an excimer laser as well.

3. Wavefront-guided LASIK:

This procedure involves creating a 3D map of your eye, which guides the laser during the reshaping process. It allows for more personalized treatment.

4. Topography-Guided LASIK:

This type of LASIK uses advanced mapping technology to address corneal irregularities, improve visual sharpness, reduce astigmatism, and enhance overall vision quality.

What are the benefits of LASIK treatment?

LASIK offers several advantages over glasses or contact lenses:

1. Improved vision quality: 

LASIK can provide clearer and sharper vision by correcting refractive errors and astigmatism.

2. Convenience and freedom:

After LASIK, you won’t have to rely on glasses or contacts for daily activities. You can enjoy sports and outdoor activities and wake up without reaching for your glasses.

3. Cost savings in the long run:

Although LASIK requires an initial investment, it can be cost-effective over time compared to continuously buying glasses or contacts.

4. Quick recovery and minimal discomfort:

LASIK is generally a quick procedure, typically taking only a few minutes per eye. The recovery time is relatively short, with most people experiencing improved vision within a day or two. Discomfort during the healing process is minimal for most patients.

5. Proven safety and effectiveness:

LASIK has been performed for many years and has a high success rate. As long as it’s performed by experienced surgeons using advanced technology, it is considered safe.

Who are the ideal candidates for LASIK eye surgery?

A. Minimum Age Requirement:

You should be at least 18 years old to undergo LASIK eye surgery because, by this time, your eyesight and prescription tend to stabilize.

B. Stable Vision Prescription:

It is important to have a stable vision prescription before considering LASIK treatment. Your prescription should remain relatively unchanged for a period of 6 to 12 months before the procedure. Having your vision checked by an eye doctor before surgery is recommended.

C. Absence of Dry Eye:

It is crucial to ensure that you do not have dry eye before undergoing LASIK surgery, as it can affect recovery. If you have dry eyes, your eye doctor may suggest ways to treat the condition before proceeding with the LASIK surgery.

D. Prescription within Suitable Limits:

LASIK surgery is typically effective for vision prescriptions within certain limits. For near-sightedness, the prescription limit is around -11 diopters; for farsightedness, it is approximately +5 diopters; and for astigmatism, it is around -5 diopters. If your vision prescription exceeds these limits, alternative procedures may be more suitable for achieving optimal results.

E. Corneal Thickness:

The thickness of your cornea is another important factor in LASIK eye surgery. Your cornea must have a sufficient thickness for the eye surgeon to safely create the corneal flap during the procedure.

It’s important to consult an eye doctor for LASIK surgery to determine if the treatment is suitable for you. They will assess your individual circumstances and provide personalized recommendations for the most appropriate treatment option.

LASIK treatment may not be suitable for you


A. If you have certain medical conditions:

If you have certain medical conditions like autoimmune diseases (e.g., rheumatoid arthritis), immunodeficiency (e.g., HIV), or diabetes, or if you are taking specific medications such as retinoic acid or steroids, it may affect your recovery after LASIK surgery.

B. If you engage in contact sports:

Sports that involve forceful blows or kicks to the face and eyes, like wrestling, boxing, kabaddi, or martial arts, are not recommended for LASIK candidates due to the potential risk of injury.

C. Underlying Eye Conditions:

LASIK may not be suitable if you have severe dry eye syndrome, corneal abnormalities, or thin corneas, as these factors can affect the healing process after the surgery.

What are the potential risks of LASIK surgery?

Although there are many benefits of LASIK treatment, some people do experience some temporary side effects after LASIK eye surgery:

  • Hazy or blurry vision
  • Difficulty with night vision or driving at night
  • Dryness, scratchiness, and other symptoms of dry eye
  • Glare, halos, or starbursts around lights
  • Light sensitivity
  • Discomfort or mild pain
  • Small pink or red patches on the white of the eye
  • Corneal thinning: Ectasia is a condition that can occur after LASIK eye surgery. It involves a thinning and bulging of the cornea, which is the clear front part of the eye. This condition can cause blurry and distorted vision.

It’s important to note that these side effects and risks usually resolve on their own within a short period, and additional treatment is rarely required.

Post LASIK care: Do’s and Don’ts after LASIK Treatment.

After undergoing LASIK treatment, here are some important do’s and don’ts to ensure a successful and comfortable recovery.

7 Tips to Maximize Your Recovery After LASIK Eye Surgery


1. Do Use Artificial Tears:

Use the prescribed artificial tears or lubricating eye drops as directed by your doctor. These drops help keep your eyes hydrated, nourished, and alleviate discomfort during recovery.

2. Do Maintain a Clean Environment:

Ensure you have a clean and germ-free environment to minimize the risk of post-LASIK infections. Wash and dry your hands thoroughly before touching your eyes or applying eye drops.

3. Do Follow the Prescribed Medication Regimen:

Attend follow-up appointments to assess your healing progress and address any concerns. Discuss any psychological or medicinal concerns with your doctor during these appointments.

4. Do Follow-Up with Your Doctor:

Attend follow-up appointments with your eye doctor within 24 to 48 hours after LASIK eye surgery to monitor your healing progress and address any concerns. These appointments should be continued for at least six months post-surgery.

5. Do Wear Eye Protection:

During the initial healing period, consider wearing protective eye shields such as sunglasses to shield your eyes from bright light, UV rays, and dust particles. This will help protect your eyes as they recover from the surgery.

6. Do Opt for a Healthy Lifestyle:

Adopting a healthy lifestyle by quitting smoking, maintaining cleanliness, and consuming nutritious foods such as fresh fruits, chicken, eggs, fish, and staying properly hydrated can greatly contribute to a speedy recovery after LASIK eye surgery. 

And, lastly, be patient! Recovery timelines vary among individuals, so it’s important to be patient and trust the process. Avoid comparing your recovery to others, and contact your eye doctor if you have any persistent concerns.

5 Things to Avoid to Recover Well from LASIK Treatment


1. Don’t Rub Your Eyes:

To promote quick healing and reduce the risk of infection, it’s important to refrain from touching or rubbing your eyes after LASIK surgery. If you experience persistent itching, consult your eye specialist for appropriate treatment.

2. Don’t Wear Eye Makeup:

Avoid eye makeup for at least a week after LASIK eye surgery to protect your eyes from infections. Make sure to check with your doctor to find out when it’s okay to start wearing makeup again after LASIK eye surgery. Until then, it’s best to keep your makeup application limited to below the nose area. When you start wearing makeup again, remember to be careful and maintain good hygiene to avoid any bacteria build up that could harm your eyes.

3. Don’t Go Swimming:

For a few weeks after LASIK eye surgery, avoiding swimming and bathing in hot water is advisable to reduce the risk of infection. Chlorinated water and hot tubs may contain bacteria and chemicals that irritate or infect the eyes.

4. Don’t Expose Yourself to Dusty or Smoky Environments:

To support healthy recovery, stay away from dusty or smoky surroundings for a while. These environments can contain dust particles that may worsen eye irritation or infection.


LASIK treatment can make a significant difference if you’re tired of blurry vision and want to improve your eyesight. Understanding the recovery process, following post-operative care instructions, and consulting with a specialist in LASIK surgery, are essential steps to achieve the best results.
