The use of computer technology in medical science has been expanding during recent years. Laser eye surgery has become increasingly more popular, while non-laser procedures have also improved. Although

chirurgia refrattiva Milano think that LASIK is the only kind of refractive surgery, there are actually various kinds of eye surgery for correcting vision.

Laser Eye Surgery

These procedures involve the use of a laser to reshape the cornea in order to enhance the eye’s ability to focus. There are lots of forms of laser eye surgery, such as LASIK, LASEK, Intralense or PRK.

Laser-Assisted In Situ Keratomileusis (LASIK)

The surgeon removes a flap through the outer and middle layer of the cornea and then uses an excimer laser to remove tissue under the flap. This sort of eye surgery usually takes about one minute per eye.

Laser Epithelial Keratomileusis (LASEK)

LASEK is very similar to LASIK, but for the fact that the flap is cut only from the outer layer of the cornea (epithelium). It’s used mainly for patients with thin corneas, who are not eligible for LASIK. It’s a newer procedure with a couple of drawbacks, for example more distress and slightly longer healing period.

IntraLense

This sort of eye surgery is also very similar to LASIK, but that the surgeon uses an extra laser rather than a blade to create the flap in the outer layers.

Photorefractive Keratectomy (PRK)

This process is used to treat astigmatism, nearsightedness and mild to moderate farsightedness. A laser can be used to remove tissue from the outer layer of the cornea and correct eyesight. The surgeon does not cut any flap in the cornea. The operation usually lasts less than a minute.

Non-laser Eye Surgery

These surgical procedures involve improving vision by cutting into the surface of the eye, reshaping the cornea or utilizing low heating waves.

Astigmatic Keratotomy Incisions

This process can be used to correct moderate astigmatism. Bulgy regions of the cornea are reshaped by using a blade. Many patients undergo such a remedy in conjunction with different types of eye surgery. But, it is now less often used than laser eye surgery procedures, such as PRK or LASIK.

Implantable Contact Lenses

These are implantation devices used to treat acute farsightedness and nearsightedness. The lens is placed behind the iris, in the front of the natural lens of the eye. Unlike normal contact lenses, you can’t feel them and they don’t require maintenance. The process can take from 6 to 20 minutes.

Intraocular Lenses (IOLs)

This sort of eye surgery has existed for decades now and the lenses are usually implanted during a cataract surgery to replace the natural lens of the eye. Years ago, these lenses used to help only with space vision and patients necessary to wear glasses for near vision. However, the process was improved and helps with close and intermediate vision as well.
