Difference Between LASIK and Cataract Surgery?
Understanding LASIK Surgery
LASIK, or Laser-Assisted In Situ Keratomileusis, is one of the most advanced and commonly performed vision correction surgeries. It is primarily aimed at addressing refractive errors that result in poor focus of light onto the retina. By correcting these errors, LASIK offers an alternative to glasses or contact lenses, providing clear and natural vision.
Conditions LASIK Corrects:
Nearsightedness (Myopia):
In myopia, distant objects appear blurry because light focuses in front of the retina rather than directly on it. LASIK reshapes the cornea, allowing the light to focus correctly for sharp distance vision.
Farsightedness (Hyperopia):
Individuals with hyperopia have difficulty seeing nearby objects clearly as light focuses behind the retina. LASIK adjusts the cornea’s curvature to bring nearby objects into clear focus.
Astigmatism:
This condition arises from an irregular shape of the cornea or lens, which distorts light as it enters the eye, leading to blurry or distorted vision. LASIK smoothens and reshapes the cornea to correct the irregularity and improve clarity.
How LASIK Works:
The LASIK procedure is a precise, minimally invasive surgery that involves advanced laser technology to reshape the cornea. Here’s a step-by-step breakdown:
1. Creation of a Corneal Flap:
A femtosecond laser creates a thin, hinged flap on the outer layer of the cornea (epithelium).
The surgeon gently lifts this flap to expose the underlying corneal tissue (stroma).
The flap acts as a natural bandage, promoting faster healing post-surgery.
2. Reshaping the Cornea:
A computer-controlled excimer laser removes microscopic layers of the corneal tissue with high precision.
The laser sculpts the cornea’s surface to correct the specific refractive error (myopia, hyperopia, or astigmatism).
This reshaping ensures that light entering the eye focuses correctly on the retina for clear vision.
3. Repositioning the Flap:
Once the cornea is reshaped, the flap is carefully repositioned.
The flap naturally adheres to the corneal tissue without the need for stitches, due to the eye’s natural healing process.
Advantages of LASIK:
Quick Procedure: The surgery typically takes only 15-20 minutes for both eyes.
Fast Recovery: Most patients experience significant vision improvement within 24 hours.
Long-Term Results: LASIK offers permanent correction for stable prescriptions.
Painless Experience: The procedure is performed under local anesthesia, ensuring comfort throughout.
Ideal Candidates for LASIK:
Must be at least 18 years old.
Have a stable vision prescription for at least one year.
Free from severe dry eye, corneal thinning, or other significant eye conditions.
Pregnant or nursing women may be advised to delay LASIK due to potential hormonal changes affecting vision stability.
