Causes of Cataracts

Several typical eyesight correction surgeries include LASIK, IntraLase as well as Photorefractive Keratectomy or PRK surgery.

Lasik Eye Surgery- Lasik is a 2-step vision correction procedure which has been extremely successful in the treatment of myopia, hyperopia and astigmatism. The advantages. The treatment of eye lasik surgery is completed under local anaesthesia (eye drops). The initial step in lasik, building the flap, requires around 30 seconds for each eye, while the 2nd phase, reshaping the cornea, will take around 15 seconds. There is no discomfort. Many people experience improved vision, with no eyeglasses, within a few hours of surgery.

The process- The corneal flap is generated 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 permits small quantities of tissue (100 times thinner compared to a human hair) to be removed, reshaping the cornea. The flap is next carefully repositioned exactly where it closes naturally without any stitches necessary. The whole treatment is done employing anaesthetic eye drops along with a moderate oral sedative.

The IntraLase Laser is the first step in IntraLase laser surgery and is used to produce a flap without using a blade.

The Benefits- A blade-free way of making the corneal flap which has exchanged the microkeratome (a mechanical device that uses a metal blade). Creation of the flap only requires roughly 30 seconds for each eye. It’s safer, a lot more accurate and offers much better outcomes.

Photorefractive Keratectomy- Photorefractive Keratectomy (PRK) uses the excimer laser to alter the form of the cornea. PRK is a laser treatment method that does not entail building a corneal flap. However, it’s going to take longer for the eye to recoup and there is more discomfort compared to with a LASIK procedure.

The drawback- Several patients will not be well suited for LASIK and demand a different remedy to fix their vision. An extremely slim or inappropriately shaped cornea often means patients are unsuitable for lasik vision correction.

The PRK Procedure- The surface cells of the cornea are taken out and the frontal surface on the cornea is reformed to correct the refractive error. The soft contact lens bandage is positioned on the cornea to help the recovery process. Regeneration on the corneal area often takes 3 to 4 days. Like with LASIK, the procedure is performed using anaesthetic eye drops and a mild oral sedative.
