LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK (Laser-Assisted In Situ Keratomileusis) is a popular refractive surgery that corrects vision problems such as nearsightedness, farsightedness, and astigmatism. During the procedure, a surgeon uses a laser to reshape the cornea, the clear front part of the eye, to improve the way light rays are focused onto the retina. This results in clearer vision without the need for glasses or contact lenses. LASIK is a quick procedure that typically takes about 15 minutes per eye, and patients usually experience improved vision almost immediately or within a day or two after surgery.
PRK (Photorefractive Keratectomy)
PRK (Photorefractive Keratectomy) is another type of refractive surgery similar to LASIK but with some differences in the surgical technique. In PRK, instead of creating a flap in the cornea, the outer layer of the cornea (epithelium) is completely removed before reshaping the cornea with a laser. The epithelium regenerates naturally after the procedure. PRK is often recommended for patients with thinner corneas or certain corneal irregularities that may not be suitable for LASIK. Recovery from PRK typically takes longer compared to LASIK, with gradual improvement in vision over several days to weeks.
Cataract surgery
Cataract surgery is a procedure to remove a cloudy lens (cataract) from the eye and replace it with an artificial lens implant. Cataracts develop when the natural lens of the eye becomes cloudy, causing blurry vision and difficulty seeing clearly. During cataract surgery, the cloudy lens is broken up using ultrasound energy and removed from the eye through a small incision. Once the cataract is removed, an intraocular lens (IOL) implant is inserted to replace the natural lens, restoring clear vision. Cataract surgery is typically performed on one eye at a time, with each procedure taking about 15 to 30 minutes. It is one of the most commonly performed surgeries worldwide and is highly effective in improving vision and quality of life for individuals affected by cataracts.
