Refractive Eye Surgery
Refractive surgery, also known as laser eye surgery, is a surgical procedure aimed at correcting common vision problems such as nearsightedness, farsightedness, and astigmatism. The procedure reshapes the cornea, which is the clear front part of the eye, allowing light to properly focus onto the retina for clearer vision.
Popular refractive surgery procedures include:
1. LASIK (Laser-Assisted In Situ Keratomileusis):
This procedure uses a laser to create a corneal flap, which is lifted to reshape the cornea with another laser. The flap is then repositioned, and no stitches are required. A new form of LASIK is FemtoLASIK in which flap is created with the help of femto laser instead of micro keratome. Which is far safe than simple LASIK.
2. PRK (Photorefractive Keratectomy):
This procedure involves removing the outer layer of the cornea before reshaping it with a laser. The outer layer naturally regrows over time.
3. SMILE (Small Incision Lenticule Extraction):
In this procedure, a tiny incision is made in the cornea and lenticule is removed.
