Three well-known eyesight correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery.

Lasik Eye Surgery: Lasik is a 2 step vision correction procedure which has been quite successful in treating near-sightedness, hyperopia and astigmatism. The advantages. The procedure of lasik is carried out under local anaesthesia (eye drops). The first step in lasik, building the flap, will take about 30 seconds for each eye, while the 2nd stage, reshaping the cornea, usually takes around 15 seconds. There is no discomfort during lasik vision correction. Many people benefit from improved vision, without eyeglasses, within a few hours after lasik vision correction. The process: The corneal flap is generated with the microkeratome. The flap is subsequently folded back so that the excimer laser can reshape your cornea. The speed and accuracy of the Allegretto (excimer) Laser lets small quantities of tissue (100 times thinner than a human hair) to be taken out, reshaping the cornea. The flap is then carefully repositioned exactly where it seals naturally without any stitches required. The whole lasik treatment is done utilising anaesthetic eye drops along with a moderate oral sedative.

The IntraLase Laser is the first step in IntraLase eye laser treatment and it is used to produce a flap without the use of a blade. The Advantages: A blade-free strategy for making the corneal flap which has exchanged the microkeratome (a mechanical device that uses a metal blade). Formation of the flap simply takes around 30 seconds for each eye. It’s less dangerous, far more precise and presents much better outcomes.

Photorefractive Keratectomy: Photorefractive Keratectomy (PRK) uses the excimer laser to alter the form of the cornea. PRK is a laser treatment procedure of which won’t include developing a corneal flap. Nevertheless, it takes longer for the eye to recoup and there’s more soreness than with a LASIK process.The Problem: Some patients are not ideal for LASIK and require a different treatment method to correct their eyesight. A really thin or inappropriately shaped cornea often means patients are unsuitable for lasik vision correction . The PRK Procedure: The surface cells on the cornea are eliminated and the frontal surface of the cornea is reshaped to alter the refractive error. The soft contact lens bandage is placed on the cornea to support the healing process. Regeneration of the corneal surface usually takes 3 to 4 days. Similar to LASIK, the process is carried out utilising anaesthetic eye drops and a mild oral sedative.
