The utilization of computer technology in medical science has been expanding during recent years. Laser eye surgery has become more and more popular, while non-laser procedures also have improved. Though many people believe LASIK is the only type of refractive surgery, there are actually various types of eye care for correcting vision.
Laser Eye Surgery
These procedures involve the use of a laser to reshape the cornea to be able to enhance the eye’s ability to concentrate. There are lots of types 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 through the outer and centre of the cornea then uses an excimer laser to remove tissue under the flap. This type of eye surgery usually takes about 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). It is used mainly for patients with thin corneas, who aren’t eligible for LASIK. It is a newer process with a couple of drawbacks, for example more discomfort and slightly longer healing period.
This type of eye surgery is also quite similar to LASIK, except that the surgeon uses an excess laser instead of a blade to create the flap in the outer layers.
A laser is used to remove tissue from the outer layer of the cornea and proper eyesight. The surgeon does not cut any flap in the cornea. The surgery usually lasts under a minute.
Non-laser Eye Surgery
These surgical procedures involve enhancing 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 frequent non-laser eye surgery procedures.
Astigmatic Keratotomy Incisions
This process can be used to correct mild astigmatism. Bulgy areas of the cornea are reshaped by using a blade. Many patients experience such a remedy together with other kinds of eye surgery. But, it is now less frequently used than laser eye surgery procedures, such as PRK or LASIK.
chirurgia refrattiva Milano are implantation devices used to treat severe 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 sense them and they don’t 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 usually implanted during a cataract surgery to replace the natural lens of the eye. Years ago, these lenses utilized to help only with space vision and patients necessary to wear glasses for near vision. However, the process was enhanced and helps with close and intermediate vision as well.
