The use of computer technology in medical science has been expanding during the past couple of decades. Laser eye surgery has become more and more popular, while non-laser procedures also have improved. Although many men and women believe LASIK is the sole kind of refractive surgery, there are actually various types 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 focus. There are lots of forms of laser eye surgery, such as LASIK, LASEK, Intralense or PRK.

Laser-Assisted In Situ Keratomileusis (LASIK)

This process is used to treat astigmatism, nearsightedness and farsightedness. The surgeon removes a flap during 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 approximately one minute per eye.

LASEK is quite similar to LASIK, except for the fact that the flap is cut only from the outer layer of the cornea (epithelium). chirurgia refrattiva Milano 's used mostly for patients with thin corneas, who are not eligible for LASIK. It is a newer process with a couple of drawbacks, for example more distress and slightly longer recovery period.


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.

Photorefractive Keratectomy (PRK)

This procedure 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 retina and proper vision. The surgeon doesn't cut any flap in the cornea. The operation generally lasts under a moment.

Non-laser Eye Surgery

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

Astigmatic Keratotomy Incisions

This process can be used to correct moderate astigmatism. Bulgy regions of the retina are mesmerized by using a blade. Many patients experience this kind of treatment in conjunction with different types of eye surgery. But, it is currently less often used than laser eye surgery procedures, such as PRK or LASIK.

Implantable Contact Lenses

These are implantation apparatus 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't feel them and they do not need 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 often implanted during a cataract operation to replace the natural lens of the eye. Years ago, these lenses used to help only with space patients and vision needed to wear glasses for close vision. However, the process was improved and helps with close and intermediate vision as well.
