Vision Correction Surgeries: Lasik Surgery, IntraLase And Photorefractive Keratectomy (PRK) Eye Surgery
3 well-known eye correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery.
Lasik Eye Surgery- Lasik is a 2- step eyesight correction treatment that has been extremely successful in treating myopia, hyperopia and astigmatism. The advantages. The surgery of lasik is performed under local anaesthesia (eye drops). The first task in lasik, making the flap, will take roughly 30 seconds for each eye, whilst the second phase, reshaping the cornea, will take approximately 15 seconds. There is absolutely no pain during lasik eye surgery. The majority love better vision, with no eyeglasses, within a few hours of surgery. The process- The corneal flap is created using the microkeratome. The flap is subsequently folded back so the excimer laser can reshape your cornea. The speed and precision with the Allegretto (excimer) Laser allows tiny quantities of tissue (one hundred times thinner than a human hair) to be taken off, reshaping the cornea. The flap is next cautiously repositioned where it seals naturally with no stitches needed. The whole treatment is performed employing anaesthetic eye drops and a moderate oral sedative.
The IntraLase Laser is the first step in IntraLase eye laser treatment and is used to create a flap without the application of a blade. The Benefits- A blade-free means of making the corneal flap that has exchanged the microkeratome (a mechanical device that uses a metal blade). Formation of the flap simply takes around 30 seconds per eye. It’s safer, more exact as well as offers much better results.
Photorefractive Keratectomy- Photorefractive Keratectomy (PRK) uses the excimer laser to change the form of the cornea. PRK is alaser vision correction procedure of which does not involve creating a corneal flap. Nonetheless, it will take longer for the eye to recuperate and there is more soreness when compared with with a LASIK process.The drawback- Several patients are not well suited for LASIK and demand a different treatment method to improve their vision. An extremely slim or inappropriately shaped cornea can mean patients are unsuitable for lasik vision correction. The PRK Procedure- The surface cells of the cornea are removed and the frontal surface on the cornea is reshaped to improve the refractive error. A soft contact lens bandage is placed on the cornea to aid the process of recovery. Regeneration on the corneal area usually takes 3 to 4 days. As with LASIK, the procedure is done utilizing anaesthetic eye drops and a mild oral sedative.
