What is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is a popular refractive surgery that reshapes the cornea to correct vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It is a highly effective procedure that can significantly reduce or eliminate the need for glasses or contact lenses.

During LASIK surgery, a thin flap is created on the cornea, which is then lifted to allow a excimer laser to precisely reshape the underlying corneal tissue. The flap is then carefully repositioned, where it naturally adheres without stitches. The procedure is typically quick, often completed within minutes for both eyes, and most patients experience rapid vision improvement.

LASIK Eye Surgery Types

Standard LASIK: Uses a microkeratome blade to create the corneal flap.
Femto-LASIK (All-Laser LASIK/Blade-Free LASIK): Uses a femtosecond laser to create the corneal flap, offering higher precision.
Contoura Vision LASIK: A highly advanced personalized LASIK that uses detailed corneal mapping to correct even minute irregularities.
PRK (Photorefractive Keratectomy): An alternative to LASIK where no flap is created; the outer layer of the cornea is removed before laser reshaping.

Factors Affecting LASIK

Age: Patients should generally be 18 years or older with stable vision.
Stable Prescription: Vision prescription should not have changed significantly for at least one year.
Corneal Thickness: Adequate corneal thickness is crucial for flap creation and reshaping.
Overall Eye Health: Absence of other eye conditions like glaucoma, severe dry eyes, or uncontrolled diabetes.
Realistic Expectations: Understanding the potential outcomes and limitations of the surgery.

Benefits of LASIK Eye Surgery

Improved Vision: Significant reduction or elimination of dependence on glasses or contact lenses.

Quick Results: Most patients experience improved vision within a day or two.

Minimally Invasive: The procedure is relatively quick and involves minimal discomfort.

High Success Rate: LASIK has a high success rate with excellent safety profiles.

Enhanced Quality of Life: Freedom from eyewear can lead to greater convenience in daily activities, sports, and hobbies.

How Does LASIK Work?

LASIK involves two primary steps:

Flap Creation:

A very thin, hinged flap is created on the surface of the cornea. This can be done either with a microkeratome blade or a femtosecond laser (for all-laser LASIK). The flap is then gently folded back, exposing the underlying corneal tissue.

Corneal Reshaping:

An excimer laser, guided by sophisticated computer software based on your unique eye measurements, is used to remove microscopic amounts of corneal tissue. This precisely reshapes the cornea, correcting the refractive error. For myopia, the cornea is flattened; for hyperopia, it is steepened; and for astigmatism, irregularities are smoothed.

Once the laser reshaping is complete, the corneal flap is carefully repositioned. It naturally adheres to the underlying stroma without the need for stitches, and healing begins rapidly.

Preparing for LASIK

Comprehensive Eye Exam: Undergo a thorough eye examination to determine your candidacy.

Stop Contact Lens Wear: Discontinue wearing soft contact lenses for at least 1-2 weeks, and hard lenses for longer, as they can alter corneal shape.

Avoid Eye Makeup: Do not wear eye makeup, lotions, or perfumes on the day before and day of surgery.

Arrange Transportation: You will need someone to drive you home after the procedure.

Ask Questions: Discuss all your concerns and questions with your surgeon before the surgery.

Post-LASIK Care

Rest Your Eyes: Immediately after surgery, rest with your eyes closed for a few hours.

Use Eye Drops: Administer prescribed eye drops diligently to prevent infection and inflammation.

Avoid Rubbing Eyes: Refrain from rubbing your eyes, especially during the initial healing period.

Wear Protective Eyewear: Use eye shields while sleeping for the first few nights to prevent accidental rubbing.

Avoid Water Exposure: Steer clear of swimming pools, hot tubs, and saunas for several weeks.

Attend Follow-up Appointments: Regular follow-up visits are essential for monitoring your healing progress.
