The use of computer technology in medical science has been extending during the past couple of years. Laser eye surgery has become increasingly more popular, while non-laser processes also have improved. Though many men and women believe LASIK is the only kind of refractive surgery, there are in fact various types 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 several forms of laser eye surgery, such as LASIK, LASEK, Intralense or PRK.

This process is used to treat astigmatism, nearsightedness and farsightedness. The surgeon removes a flap during the outer and centre of the cornea then uses an excimer laser to remove tissue under the flap. This sort of eye surgery usually takes approximately one minute per eye.

LASEK is quite similar to LASIK, but 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, for example more distress and slightly longer recovery period.


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

Non-laser Eye Surgery

These surgical procedures involve improving vision by cutting into the surface of the eye, reshaping the cornea or utilizing low heat radio waves. Astigmatic keratotomy incisions, intraocular lenses and implantable contact lenses are among the most frequent non-laser eye surgery procedures.

This process is used to correct moderate astigmatism. Bulgy regions of the cornea are reshaped using a blade. chirurgia refrattiva Milano experience such a remedy in conjunction with different types of eye surgery.

This sort of eye surgery has existed for many decades now and the lenses are often implanted during a cataract operation to replace the natural lens of the eye. Years past, these lenses utilized to assist only with distance patients and vision needed to wear glasses for close vision. However, the process was enhanced and helps with intermediate and close vision too.
