Vision Eyecare Lasik Health and Medical News/Updates

3 typical eyesight 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 quite successful in treating nearsightedness, hyperopia and astigmatism. The Benefits: The treatment of lasik is performed under local anaesthesia (eye drops). The first step in lasik eye surgery, making the flap, will take about 30 seconds for each eye, whilst the second step in lasik eye correction, reshaping the cornea, takes around 15 seconds. There’s no pain. Most people take joy in improved vision, with no eyeglasses, about a few hours of surgery. The process: The corneal flap is designed using the microkeratome. The flap is subsequently folded back so that the excimer laser can reshape your cornea. The speed and accuracy of the Allegretto (excimer) Laser enables minor quantities of tissue (one hundred times thinner than the usual human hair) to be removed, reshaping the cornea. The flap is next meticulously repositioned exactly where it seals naturally without any stitches needed. The entire treatment is performed utilizing anaesthetic eye drops and a moderate oral sedative.

The IntraLase Laser is the initial step in IntraLase laser surgery and it is used to produce a flap without the application of a blade. The Benefits: A blade-free way of developing the corneal flap which has replaced the microkeratome (a mechanical device that uses a metal blade). Formation of the flap only requires nearly 30 seconds for each eye. It is less dangerous, a lot more exact and presents greater results.

Photorefractive Keratectomy: Photorefractive Keratectomy (PRK) uses the excimer laser to change the form of the cornea. PRK is a eye laser treatment method which does not entail making a corneal flap. However, it will take more time for the eye to recover and there is more soreness than with a LASIK procedure. The Issue: Many patients aren’t suited to lasik vision correction and need a different remedy to improve their eyesight. A very thin or inappropriately shaped cornea often means patients are unsuitable for lasik vision correction. The PRK Procedure: The surface cells from the cornea are taken away and the frontal surface on the cornea is reformed to correct the refractive error. A soft contact lens bandage is placed on the cornea to support the recovery process. Regrowth on the corneal area usually takes 3 to 4 days. As with LASIK, process is performed using anaesthetic eye drops and a mild oral sedative.
