- LASIK (Laser-Assisted In Situ Keratomileusis): LASIK is a popular and well-established laser eye surgery for correcting refractive vision problems, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. During the procedure, a thin flap is created on the cornea using a microkeratome or femtosecond laser. The surgeon then lifts the flap and uses an excimer laser to reshape the underlying corneal tissue, correcting the refractive error. The flap is then repositioned, and the cornea heals naturally without the need for stitches.
- LASEK (Laser-Assisted Sub-Epithelial Keratectomy): LASEK is a variation of LASIK that is generally employed when a patient’s cornea is too thin or steep for LASIK. Instead of creating a corneal flap, LASEK involves the removal of the thin outer layer of the cornea called the epithelium. The surgeon uses alcohol solution to loosen the epithelium, then lifts it to expose the underlying cornea, where the excimer laser is applied to reshape the cornea and correct the refractive error. After the laser treatment, the epithelial layer is repositioned and covered with a soft contact lens to aid in the healing process.
It’s worth noting that both LASIK and LASEK are effective procedures with high success rates for improving vision and reducing the need for glasses or contact lenses. However, the suitability of each procedure depends on several factors, including the patient’s eye health, corneal thickness, refractive error, and individual preferences. The decision on which procedure to choose is typically made after a thorough examination and consultation with an ophthalmologist or refractive surgeon.
