Introduction
Clear vision is vital for performing everyday tasks, enjoying hobbies, and experiencing the world around us. Refractive eye surgery aims to enhance vision by correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. It is a safe and effective procedure that reshapes the cornea to improve its focusing ability.
Types of Refractive Eye Surgery
1. LASIK (Laser-Assisted In Situ Keratomileusis):
This popular procedure involves creating a thin flap on the cornea, which is then lifted to allow a laser to reshape the underlying tissue. The flap is then repositioned, promoting rapid healing and minimal discomfort.
2. PRK (Photorefractive Keratectomy):
PRK is an alternative to LASIK, suitable for individuals with thin corneas or certain corneal irregularities. In this procedure, the cornea's outer layer is gently removed to access the underlying tissue, which is then reshaped using a laser.
3. SMILE (Small Incision Lenticule Extraction):
SMILE is a minimally invasive procedure that corrects myopia (nearsightedness). It involves creating a small, precise incision to remove a lenticular, reshaping the cornea, and improving vision.
4. LASEK (Laser-Assisted Sub epithelial Keratectomy):
LASEK combines the advantages of LASIK and PRK. The epithelium, a thin layer on the cornea, is treated with alcohol to loosen it, allowing the surgeon to reshape the cornea.
5. RLE (Refractive Lens Exchange):
RLE is a procedure primarily used to correct presbyopia or extreme refractive errors. The natural lens of the eye is replaced with an artificial intraocular lens (IOL) to restore clear vision.
6. Phasic IOLs (Intraocular Lenses):
Phasic IOLs are implantable lenses placed in front of the natural lens of the eye. They are suitable for individuals with high refractive errors who may not be eligible for other types of refractive surgeries.
