3 Standard Vision Correction Surgeries: Lasik Eye Surgery, IntraLase And Photorefractive Keratectomy (PRK) Surgery
3 well-known eye correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery. Lasik Eye Surgery: Lasik is actually a 2-step eyesight correction treatment which has been very successful in treating nearsightedness, hyperopia and astigmatism. The Benefits: The Procedure of lasik eye surgery is carried out under local anaesthesia (eye drops). The first task in lasik eye surgery, building the flap, will take around 30 seconds for each eye, while the 2nd stage in lasik eye surgery, reshaping the cornea, usually takes approximately 15 seconds. There isn’t any soreness. Most people experience better vision, without glasses, about a few hours of surgery. The Procedure: The corneal flap is designed with the microkeratome. The flap is then folded back so that the excimer laser can reshape your cornea. The speed and precision of the Allegretto (excimer) Laser makes it possible for tiny quantities of tissue (100 times thinner compared to a human hair) to be taken out, reshaping the cornea. The flap is then meticulously repositioned where it closes naturally without any stitches needed. The whole treatment is done utilizing anaesthetic eye drops and a mild oral sedative.
The IntraLase Laser is the first step in IntraLase laser vision correction and it is used to create a flap without the application of a blade. The Benefits: A blade-free way of producing the corneal flap which has exchanged the microkeratome (a mechanical device which utilizes a metal blade). Formation of the flap merely requires around 30 seconds for each eye. It is less dangerous, much more accurate and delivers superior outcomes.
Photorefractive Keratectomy: Photorefractive Keratectomy (PRK) uses the excimer laser to change the form of the cornea. PRK is a eye surgery method of which won’t include making a corneal flap. However, it’s going to take more time for the eye to recoup and there’s more discomfort than with a LASIK procedure. The Issue: Many patients aren’t suited to LASIK and demand a different remedy to correct their vision. A very thin or inappropriately shaped cornea can indicate patients are not fit for lasik eye surgery. The PRK Procedure: The surface cells from the cornea are eliminated and the frontal surface of the cornea is reshaped to fix the refractive error. A soft contact lens bandage is put on the cornea to support the process of recovery. Regrowth on the corneal area usually takes 3 to 4 days. Just like LASIK, process is carried out utilizing anaesthetic eye drops and a mild oral sedative.
