Laser Eye Surgery - Comparison Of LASIK, PRK And LASEK

More than 100,000 people in the UK undergo laser eye treatment every year. The surgery corrects the patient's vision by shaping the cornea, which controls how the eye focuses, with a very precise laser. Between 80 and 98 percent of treatment sufficient to improve the patient no longer needs either glasses or contact lenses.

Laser Eye Surgery

Currently, there are two popular methods of laser eye surgery. The most common treatment is laser LASIK. In Lasik, a small incision in the cornea to create a flap. Laser treatment can be performed. Vision loss can occur 20 to 30 seconds during the procedure. Lasek in the epithelium is removed before the cornea is reshaped with a laser. Laser Eye Treatment takes about 15 minutes total.

For many patients, LASIK is a much more convenient than Lasek treatment. After suffering Lasek, the patient may experience moderate levels of pain for about 24 hours after surgery. Extreme sensitivity to light is also common for the first two days and have to wear sunglasses outdoors for three months. Also may remain blurred vision or blurred for a week and takes about a month before the patient's vision "settle" and the final results of surgery are known. With the Lasik treatment there is very little discomfort after the surgery and the results of surgery are evident much more quickly. First vision must be much less diffuse, after suffering Lasek, and should dispel the dark within 48 hours. Lasik patients will probably be able to see the day after treatment.

For some patients, PRK is recommended over LASIK LASEK, or if the patient is very thin cornea. PRK and LASEK was the pioneer works using the excimer laser to remove a thin layer of cells from the surface of the cornea in the eye movement. No cutting is required. The biggest difference between LASEK and PRK is that the cells are scraped and PRK the epithelium grows back after treatment, which lasts for several days. In LASEK, epithelium is removed and a weak alcohol solution and then replaced after surgery. Contact lenses are worn for several days to hold it in place.

PRK has been around for over a decade and to date there appears to be no adverse effects long term. Lasek is also considered relatively low risk. This is largely because no incision is required for surgery in one of these laser treatments. Lasik, despite its advantages, is considered the most dangerous form of laser eye surgery. Potential complications include corneal ectasia, where a buildup of pressure occurs behind the cornea weakened. Additional surgery is needed to remedy this if not a rapid degeneration may occur in the eyes.

The effects of laser eye surgery is permanent, but no treatment can prevent other age-related deterioration.
