Three Restorative Treatments To Correct Poor Eye Sight
Several popular eye correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery.
Lasik Eye Surgery: Lasik is actually a 2step vision correction treatment that has been extremely successful in treating myopia, hyperopia and astigmatism. The Benefits. The surgery of lasik eye surgery is carried out under local anaesthesia (eye drops). The first step in lasik, building the flap, will take around 30 seconds per eye, whilst the 2nd stage, reshaping the cornea, requires approximately 15 seconds. There isn’t any soreness during lasik eye surgery. Most people take joy in better eyesight, without eyeglasses, within a few hours after lasik. The process: The corneal flap is generated with the microkeratome. The flap is then folded back so the excimer laser can reshape your cornea. The speed and accuracy of the Allegretto (excimer) Laser lets very small amounts of tissue (one hundred times slimmer than a human hair) to be removed, reshaping the cornea. The flap is next cautiously repositioned exactly where it seals naturally without any stitches needed. Your entire lasik treatment is done employing anaesthetic eye drops and a mild oral sedative.
The IntraLase Laser is the first step in IntraLase laser vision correction and is utilized to create a flap without the usage of a blade. The Benefits: A blade-free means of making the corneal flap which has replaced the microkeratome (a mechanical device that uses a metal blade). Creation of the flap only takes roughly 30 seconds each eye. It’s safer, much more exact and offers superior results.
Photorefractive Keratectomy: Photorefractive Keratectomy (PRK) utilizes the excimer laser to change the form of the cornea. PRK is alaser treatment method that does not include developing a corneal flap. Even so, it’s going to take longer for the eye to recoup and there’s more discomfort as compared to with a LASIK process.The Problem: Many patients are not ideal for LASIK and require a different treatment to improve their eyesight. An extremely slim or inappropriately shaped cornea often means patients are unsuitable for lasik eye surgery . The PRK Procedure: The surface cells from the cornea are taken away and the frontal surface on the cornea is reformed to take care of the refractive error. A soft contact lens bandage is put on the cornea to aid the recovery process. Regeneration of the corneal surface usually takes 3 to 4 days. Much like LASIK, the procedure is carried out using anaesthetic eye drops and a mild oral sedative.
