DIFFERENT TYPES OF EYE SURGERY AND THEIR EFFECTIVENESS

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 many men and women think that LASIK is the sole type of refractive surgery, there are actually various kinds of eye care for correcting vision.

Laser Eye Surgery

These procedures involve using a laser to reshape the cornea in order to improve the eye’s ability to concentrate. There are chirurgia refrattiva Milano of laser eye surgery, such as LASIK, LASEK, Intralense or PRK.

Laser-Assisted In Situ Keratomileusis (LASIK)

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

Laser Epithelial Keratomileusis (LASEK)

LASEK is quite similar to LASIK, except for the fact that the flap is cut only from the outer layer of the cornea (epithelium). It is used mainly for patients with thin corneas, who aren’t qualified for LASIK. It is a newer process with a couple of drawbacks, such as more discomfort and slightly longer recovery period.

IntraLense

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



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

Non-laser Eye Surgery

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

Astigmatic Keratotomy Incisions

This procedure is used to correct mild astigmatism. Bulgy regions of the retina are mesmerized using a blade. Many patients experience this kind of treatment in conjunction with other types of eye surgery. However, it is currently 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 front of the natural lens of the eye. Unlike ordinary contact lenses, you can not sense them and they don’t require maintenance. The procedure can take from 6 to 20 minutes.

Intraocular Lenses (IOLs)

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