Overview

LASIK (Laser-Assisted In Situ Keratomileusis) is a popular refractive eye surgery that corrects vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina, resulting in clearer vision.

A common concern among ophthalmologists and patients is, "Why rely on prosthesis when it's possible to restore natural vision with all its inherent benefits, beyond just cosmetic?" The solution to these doubts and uncertainties is found in LASIK surgery.

Signs and Symptoms

• Blurred vision due to refractive errors.
• Difficulty seeing at a distance (myopia).
• Difficulty seeing close objects (hyperopia).
• Distorted or blurred vision at any distance (astigmatism).

Types of LASIK

Conventional LASIK:

Uses a microkeratome blade to create a corneal flap.

Bladeless LASIK (All-Laser LASIK):

Utilizes femtosecond laser to create the corneal flap.

Wavefront-Guided LASIK:

Customizes the procedure based on the unique characteristics of the patient's eyes.

Topography-Guided LASIK:

Corrects both refractive errors and corneal irregularities.

Diagnosis

Prior to undergoing LASIK surgery, patients undergo a comprehensive eye examination to determine their suitability. This includes:

• Detailed measurement of the eye's shape and thickness.
• Corneal mapping to assess the curvature.
• Pupil size measurement in different lighting conditions.
• Comprehensive review of eye health and history.

Preoperative Before the Preparation:

• Refraction under cycloplegia
• Corneal topography
• Aberrometry
• Ultrasonic pachymetry (to measure thickness of cornea)
• Detailed retina examination
• Intraocular pressure examination
• Informed consent procedure

Treatment

Medications:

• Antibiotic Eye Drops: Prevent infection post-surgery.
• Anti-inflammatory Eye Drops: Reduce inflammation and promote healing.

Non-Surgical Interventions:

• Prescription Glasses or Contact Lenses: Recommended for those not suitable for LASIK.

LASIK Procedure:

• Preparation: The eye is numbed with anesthetic drops to ensure comfort during the procedure.
• Corneal Flap Creation: A thin flap is created on the cornea's surface, either with a microkeratome blade or a femtosecond laser.
• Corneal Reshaping: An excimer laser is used to remove microscopic amounts of corneal tissue, reshaping it to correct vision.
• Flap Repositioning: The corneal flap is repositioned, adhering naturally without the need for stitches.

Post-Surgery Care and Recovery

• Immediate Post-Op: Patients may experience mild discomfort, dryness, or blurred vision immediately after surgery, which typically resolves within a few days.
• Follow-Up Visits: Scheduled to monitor healing and ensure optimal results.
• Lifestyle Adjustments: Patients are advised to avoid strenuous activities, swimming, and eye makeup for a few weeks to facilitate healing.

FAQ

• Who is a good candidate for LASIK?

  Suitable candidates are typically over 18, have stable vision prescriptions, and are free of eye diseases. A comprehensive eye exam determines eligibility.

• Is LASIK painful?

  LASIK is generally not painful due to numbing eye drops. Some discomfort or mild irritation may be felt post-surgery.

• What is the recovery time after LASIK?

  Most patients experience improved vision within 24 hours and can resume normal activities within a few days. Complete healing may take a few weeks.

• Are there risks associated with LASIK?

  Potential risks include dry eyes, glare, halos around lights, and under- or over-correction of vision. These are rare and often temporary.

• How long do the results of LASIK last?

  LASIK results are typically long-lasting, but vision changes due to aging (presbyopia) may still occur, requiring reading glasses or further treatment.

• Can LASIK be performed on both eyes at the same time?

  Yes, LASIK is commonly performed on both eyes during the same session for convenience and efficiency.

• What should I expect during a LASIK consultation?

  During a consultation, the ophthalmologist will evaluate your eye health, discuss your vision goals, and determine if LASIK is the right option for you.
