Three well-known vision correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery.
Lasik Eye Surgery- Lasik is a 2-step vision correction treatment which has been very successful in the treatment of nearsightedness, hyperopia and astigmatism. The advantages. The surgery of lasik is performed under local anaesthesia (eye drops). The first step in lasik, creating the flap, requires roughly 30 seconds per eye, whilst the second phase, reshaping the cornea, normally takes around 15 seconds. There's no soreness. Many people take joy in better vision, without glasses, within a few hours of surgery.
The process- The corneal flap is created with the microkeratome. The flap is then folded back so that the excimer laser can reshape your cornea. The speed and accuracy of the Allegretto (excimer) Laser enables small amounts of tissue (100 times thinner than the usual human hair) to be taken out, reshaping the cornea. The flap is then cautiously repositioned exactly where it seals naturally without any stitches required. The whole treatment is performed using anaesthetic eye drops and a moderate oral sedative.
The IntraLase Laser is the initial step in IntraLase eye surgery and is used to produce a flap without the usage of a blade.
The Advantages- A blade-free method of making the corneal flap that has exchanged the microkeratome (a mechanical device that utilizes a metal blade). Creation of the flap merely takes nearly 30 seconds per eye. It's safer, a lot more accurate as well as delivers superior results.
Photorefractive Keratectomy- Photorefractive Keratectomy (PRK) utilizes the excimer laser to change the shape of the cornea. PRK is a eye surgery procedure which doesn't entail creating a corneal flap. Nonetheless, it takes longer for the eye to recoup and there's more discomfort than with a LASIK process.
The Issue- Some patients will not be ideal for LASIK and require a different treatment method to correct their vision. A really slim or inappropriately shaped cornea often means patients are unsuitable for lasik eye surgery.
The PRK Procedure- The surface cells on the cornea are taken away and the frontal surface of the cornea is reformed to improve the refractive error. The soft contact lens bandage is put on the cornea to aid the recovery process. Regrowth of the corneal area usually takes 3 to 4 days. Like with LASIK, process is performed using anaesthetic eye drops and a mild oral sedative.
