Causes of Cataracts

Several typical eyesight correction surgeries include LASIK, IntraLase as well as Photorefractive Keratectomy or PRK surgery. Lasik Eye Surgery: Lasik is a 2-step vision correction procedure which has been extremely successful in the treatment of myopia, hyperopia and astigmatism. The Advantages: The treatment of eye lasik surgery is completed under local anaesthesia (eye drops). The initial step in lasik, building the flap, requires around 30 seconds for each eye, while the 2nd phase in lasik eye correction, reshaping the cornea, takes approximately 15 seconds. There is absolutely no discomfort. Most people love better eyesight, with no glasses, within a few hours of surgery. The process: The corneal flap is generated using the microkeratome. The flap is then folded back so the excimer laser can reshape your cornea. The speed and precision with the Allegretto (excimer) Laser lets small quantities of tissue (100 times thinner compared to a human hair) to be taken out, reshaping the cornea. The flap is next meticulously repositioned exactly where it closes naturally without any stitches required. Your entire treatment is completed utilizing anaesthetic eye drops and a moderate oral sedative.

The IntraLase Laser is the initial step in IntraLase laser eye treatment and is utilized to create a flap without the use of a blade. The Advantages: A blade-free method of creating the corneal flap that has replaced the microkeratome (a mechanical device that utilizes a metal blade). Creation of the flap merely requires around 30 seconds each eye. It is safer, much more exact and presents much better results.

Photorefractive Keratectomy: Photorefractive Keratectomy (PRK) uses the excimer laser to change the form of the cornea. PRK is a laser vision correction procedure of which won’t entail developing a corneal flap. However, it takes longer for the eye to recover and there is more irritation when compared with with a LASIK process. The Drawback: Several patients will not be ideal for lasik vision correction and demand a different remedy to improve their vision. An extremely slim or inappropriately shaped cornea can indicate patients are not fit for lasik surgery. The PRK Procedure: The surface cells on the cornea are eliminated and the frontal surface of the cornea is reformed to improve the refractive error. The soft contact lens bandage is positioned on the cornea to support the process of recovery. Regrowth of the corneal area usually takes 3 to 4 days. Just like LASIK, process is performed utilizing anaesthetic eye drops and a mild oral sedative.
