Different Types Of Eye Surgery And Their Effectiveness

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 procedures also have improved. Although many people think that LASIK is the only kind of refractive surgery, there are actually various kinds of eye care 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 concentrate. There are several types 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 through the outer and centre 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.

Laser Epithelial Keratomileusis (LASEK)

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

IntraLense

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

chirurgia refrattiva Milano (PRK)

This procedure is used to treat astigmatism, nearsightedness and mild to moderate farsightedness. A laser is 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 generally lasts under a moment.

Non-laser Eye Surgery

These surgical procedures involve enhancing vision by cutting into the surface of the eye, reshaping the cornea or using low heat radio 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 is used to correct moderate astigmatism. Bulgy regions of the retina are mesmerized using a blade. Many patients experience such a treatment together with other types of eye surgery. But, it’s currently less frequently used than laser eye surgery procedures, such as PRK or LASIK.

Implantable Contact Lenses

These 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 normal contact lenses, you can’t sense them and they do not need maintenance. The procedure can take from 6 to 20 minutes.



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 past, these lenses utilized to assist only with distance patients and vision necessary to wear glasses for near vision. However, the method was enhanced and helps with intermediate and close vision as well.
