LASIK eye surgery is a well-known vision correction procedure that has helped millions achieve improved eyesight without the need for glasses or contact lenses. This article provides a comprehensive overview of LASIK, covering the procedure, eligibility, benefits, risks, cost considerations, and recovery process. If you are considering LASIK, this guide will help you make an informed decision about the procedure.
What is LASIK?
LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive eye surgery designed to correct common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The procedure reshapes the cornea to ensure that light entering the eye is correctly focused onto the retina, resulting in clearer vision.
Unlike traditional vision correction methods like glasses and contact lenses, LASIK offers a long-term solution by modifying the eye’s natural structure. This makes it an attractive option for individuals looking for independence from corrective eyewear.
LASIK Procedure
The LASIK procedure is typically completed in under 30 minutes for both eyes. It involves the following steps:
Pre-Surgical Preparation
The patient undergoes a comprehensive eye examination to assess their suitability for LASIK. Measurements of the cornea’s thickness and curvature are taken to customise the treatment. The doctor may also evaluate tear production to assess the risk of dry eye after the procedure.
Anaesthetic Application
Numbing eye drops are applied to prevent discomfort during the surgery. Patients remain awake throughout the procedure, but some may be given mild sedatives to help them relax.
Flap Creation
A femtosecond laser or a microkeratome is used to create a thin corneal flap. This flap is then lifted to expose the underlying corneal tissue for reshaping.
Corneal Reshaping
An excimer laser precisely reshapes the corneal tissue to correct the refractive error. The laser removes microscopic amounts of tissue based on pre-determined measurements, ensuring a highly accurate correction.
Flap Repositioning
The corneal flap is carefully repositioned, where it naturally adheres without the need for stitches. The flap begins healing immediately, providing a smooth transition between the treated and untreated areas of the cornea.
Post-Surgery Monitoring
The patient rests briefly before leaving the clinic and is given post-operative care instructions. Some may experience mild discomfort, tearing, or light sensitivity for the first few hours.

LASIK Eligibility
Not everyone is a candidate for LASIK. The following factors determine LASIK eligibility:
- The patient must be at least 18 years old with a stable prescription for at least one year.
- The corneal thickness should be sufficient to support the procedure.
- No history of severe eye diseases, such as keratoconus or glaucoma.
- Good overall eye health with no active infections or inflammation.
- Pregnant or nursing women are advised to postpone LASIK due to hormonal changes that may affect vision stability.
- Those with autoimmune diseases or uncontrolled diabetes may not be suitable candidates due to delayed healing.
Benefits of LASIK
LASIK offers several advantages, making it a popular choice for vision correction:
- Quick Recovery: Most patients experience improved vision within 24 hours, though full stabilisation can take a few weeks.
- Reduced Dependence on Glasses and Contact Lenses: Many achieve 20/20 vision or better after surgery.
- Painless Procedure: Numbing drops ensure a comfortable experience, with minimal discomfort post-surgery.
- Long-Lasting Results: Once the cornea is reshaped, the changes remain stable over time.
- Convenience: No more dealing with fogged-up glasses or the daily maintenance of contact lenses.
LASIK Risks and Considerations
While LASIK is a widely performed procedure with high success rates, it does carry some risks:
- Dry Eyes: Some patients experience temporary dryness after surgery, which can be managed with lubricating eye drops.
- Glare and Halos: Night vision disturbances, such as glare or halos around lights, may occur initially but usually improve over time.
- Under or Overcorrection: In some cases, additional enhancement surgery may be required to refine vision results.
- Flap Complications: Though rare, improper healing of the corneal flap can cause complications such as dislocation or infection.
- Not Reversible: Unlike contact lenses or glasses, the changes made to the cornea are permanent. While enhancement procedures can address minor issues, full reversal is not possible.
LASIK Surgery Cost
The LASIK surgery cost varies based on factors such as location, surgeon expertise, technology used, and pre-/post-operative care. On average, the cost starts at ₹15,000 per eye and goes up to ₹50,000 per eye. Some clinics offer financing options or payment plans to make the procedure more accessible.
- Geographical Variations: Costs may differ based on the region and the clinic’s reputation.
- Technology Used: Advanced laser technology may result in a higher cost but offers better precision and safety.
- Surgeon’s Experience: Highly experienced surgeons may charge more for their expertise.
- Insurance Considerations: Most insurance plans do not cover LASIK as it is considered an elective procedure.
Recovery and Aftercare
Recovery after LASIK is relatively quick, but patients must follow specific aftercare guidelines:
- Avoid rubbing the eyes for at least a week to prevent flap displacement.
- Use prescribed eye drops to prevent infection and inflammation.
- Wear protective eyewear to shield the eyes from dust and accidental injury.
- Avoid swimming, saunas, and hot tubs for at least two weeks.
- Limit screen time to reduce eye strain in the first few days.
- Attend follow-up visits to monitor healing progress and address any concerns.
Conclusion
LASIK eye surgery is a transformative procedure for individuals looking to improve their vision and reduce dependence on corrective eyewear. Understanding the procedure, its benefits, eligibility criteria, risks, and cost considerations is crucial before making a decision. If you are considering LASIK, consult with an eye specialist to determine if it is the right choice for you.

FAQs
Most patients notice an improvement in vision within 24 hours. However, complete healing may take a few weeks, during which minor fluctuations in vision can occur.
No, the procedure itself is painless due to numbing eye drops. Some patients experience mild discomfort, dryness, or a foreign body sensation post-surgery, which subsides with prescribed medication.
While many achieve 20/20 vision, some may still require glasses for specific tasks such as reading or night driving, especially as they age.
Yes, LASIK can effectively correct mild to moderate astigmatism by reshaping the cornea.
In rare cases where vision changes significantly, enhancement surgery may be an option to refine the results.
