How LASIK Surgery Works
LASIK surgery involves reshaping the cornea using a laser to correct refractive errors. The procedure consists of the following steps:
- Creation of a corneal flap using a microkeratome blade or femtosecond laser.
- Reshaping of the corneal tissue using an excimer laser.
- Repositioning of the corneal flap for natural healing.
Though this process is generally safe, complications can arise, making it essential to be aware of the risks of LASIK surgery.
Common Risks of LASIK Surgery
Dry Eyes
Many patients experience dry eyes after LASIK surgery due to reduced tear production or corneal nerve damage during the surgery. This condition can cause discomfort, blurred vision, and irritation. It may persist for months, requiring artificial tears or prescription eye drops.
Halos and Glare
Some individuals report halos, glare, or starbursts around lights, particularly at night. This issue can affect night vision and make activities such as driving more difficult.
Flap Complications
Since LASIK surgery involves creating a corneal flap, complications such as flap dislocation, wrinkles, or incomplete healing can occur. These issues may require additional treatment or correction.
Under-correction or Over-correction
Not all patients achieve their desired vision correction. In some cases, the laser removes too little or too much corneal tissue, leading to under-correction or over-correction. Additional enhancement surgery may be required.
Regression
In certain cases, vision improvement achieved through LASIK may diminish over time, a condition known as regression. This can necessitate further corrective measures.
Corneal Ectasia
Corneal ectasia is a rare but serious complication where the cornea weakens and bulges outward, leading to distorted vision. This condition may require treatments such as specialized contact lenses or corneal cross-linking.
Infection and Inflammation
Though rare, LASIK surgery carries a risk of infection and inflammation. Proper post-operative care and following precautions after LASIK surgery can help minimize this risk.

Who Is at Higher Risk for Complications?
- Those with thin corneas
- Patients with dry eye syndrome
- Individuals with high refractive errors
- People with autoimmune disorders
- Individuals with unstable vision prescriptions
A thorough pre-surgery evaluation can help determine if LASIK surgery is safe for an individual.
Precautions After LASIK Surgery
To minimize complications, patients must follow essential post-operative guidelines:
- Avoid rubbing the eyes for at least two weeks.
- Use prescribed eye drops to prevent infection and dryness.
- Avoid swimming and exposure to dust for a few weeks.
- Wear protective eyewear to prevent accidental injury.
Recovery and Healing Timeline
The LASIK surgery recovery time varies for each patient, but most individuals notice improved vision within 24 hours. Complete healing may take several weeks to months. Regular follow-up visits with an eye specialist help monitor the healing process.
LASIK Surgery Experience: What to Expect
Understanding the LASIK surgery experience helps manage expectations. Patients typically undergo a quick procedure lasting 15–20 minutes. Some may experience mild discomfort or temporary vision fluctuations in the days following surgery.

Dos and Don'ts After LASIK Surgery
Dos:
- Follow the eye specialist’s instructions carefully.
- Use lubricating eye drops as recommended.
- Rest your eyes and avoid screen time for the first 24 hours.
Don'ts:
- Avoid touching or rubbing your eyes.
- Do not engage in strenuous activities for at least a week.
- Avoid cosmetics around the eyes for a few days.
Additional Risks of LASIK Surgery
Nerve Damage
In rare cases, LASIK surgery can cause nerve damage in the cornea, leading to chronic pain and discomfort.
Double Vision
Some patients may experience double vision or ghosting, affecting their ability to perform daily tasks.
Long-term Vision Fluctuations
Even after initial healing, some individuals may experience long-term vision fluctuations that require additional corrective measures.
Conclusion
While LASIK surgery offers many benefits, it is crucial to be aware of the risks of LASIK surgery before making a decision. Consulting with an experienced ophthalmologist can help determine if LASIK is the right choice based on individual eye health and lifestyle.

Frequently Asked Questions
Does LASIK work permanently?
Yes, LASIK provides permanent correction for refractive errors. However, natural aging processes, such as presbyopia or cataracts, may affect vision later in life.
What is the cost of LASIK surgery in India?
The LASIK surgery cost in India varies depending on the type of procedure, technology, and location but typically starts from 20,000 per eye.
What does LASIK stand for?
LASIK stands for Laser-Assisted In Situ Keratomileusis, a procedure that reshapes the cornea to correct vision.
Does LASIK give you 20/20 vision?
Many patients achieve 20/20 vision after LASIK, but outcomes depend on individual eye conditions and kind of refractive errors.
Is LASIK surgery safe?
LASIK is generally considered safe, but like any surgical procedure, it carries potential risks. A thorough eye examination and discussion with a specialist can help assess suitability.
What are the side effects of LASIK surgery?
Common LASIK surgery side effects include dry eyes, night glare, halos, and temporary discomfort. Most side effects resolve over time, but some may require additional treatment.
What age is best for LASIK?
The ideal age for LASIK is between 18 and 40 years, when vision is stable, and there are no age-related conditions like presbyopia or cataracts.
Is LASIK surgery painful?
No, LASIK is not painful. Numbing eye drops are used during the procedure, and most patients experience only mild discomfort during recovery.
Is LASIK 100% successful?
While LASIK is highly effective, its success rate varies. Over 95% of patients achieve 20/20 vision, depending on their initial refractive error.
Does LASIK have side effects?
Temporary side effects like dry eyes, halos, and glare may occur but typically resolve within a few weeks. Serious complications are rare.
How long does LASIK surgery take?
The actual LASIK surgery procedure takes about 15–20 minutes for both eyes. However, preparation and post-procedure observation may require a few hours.
What is the recovery time for LASIK surgery?
Most patients experience a clear vision within 24 hours, but complete healing and stabilization may take several weeks to months.
What precautions should be taken after LASIK surgery?
Patients should avoid rubbing their eyes, swimming, and exposure to dust. Following the prescribed medication regimen helps ensure proper healing.
