Laser Eye Surgery

There are several types of eye surgery, but the most common are:

• LASIK (Laser Intracranial Intraocular Skeleton): LASIK eye surgery is the best-known and most widely performed laser eye surgery. In this procedure, a thin corneal flap is created, lifted, and the cornea is reshaped using an excimer laser. The flap then falls back into place and naturally attaches to the underlying corneal tissue.

• PRK (Photorefractive Keratectomy): PRK is an older procedure than LASIK. Instead of creating a corneal flap, the outer layer of the cornea (the epithelium) is removed. An excimer laser is then used to reshape the underlying corneal tissue. The epithelium regenerates over time, usually within a week. PRK has a longer recovery period compared to LASIK. However, it may be suitable for patients with thin corneas or certain other conditions.

• LASEK (Laser-Assisted Subepithelial Keratectomy): LASEK is a combination of LASIK and PRK. In this procedure, an alcohol solution is used to partially lift the epithelium, creating a thin flap. An excimer laser is then used to reshape the underlying corneal tissue. A bandage contact lens is then placed to reposition the epithelial flap and promote healing. LASEK may be recommended for patients with thin corneas or those who are not suitable for LASIK.

• SMILE (Small Incision Lenticle Extraction): SMILE is a relatively new refractive surgery technique. A femtosecond laser is used to create a small, lens-shaped piece of tissue within the cornea. This tissue, called a lenticle, is removed through a small incision, reshaping the cornea and correcting the refractive error.

SMILE is less invasive than LASIK because it does not require the creation of a corneal flap. It is primarily used to treat myopia and astigmatism. Each laser eye surgery has its own benefits, recovery times, and suitability for certain refractive errors and corneal conditions. It is important to consult with an experienced ophthalmologist or eye surgeon. This will determine the laser eye surgery technique that best suits your individual needs and desired results.
