There are many eye laser surgery, here we present you the most relevant procedures.
PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. Though PRK recovery takes a bit longer than recovery from LASIK eye surgery, PRK is still commonly performed and offers advantages over LASIK for some patients.
Corneal inlays and onlays are tiny lenses or other optical devices inserted into the cornea to reshape the front surface of the eye to improve vision. In fact, some of these devices resemble very small contact lenses.The primary use of current corneal inlays (the term "corneal onlays" is used less frequently these days) is to improve near vision and reduce the need for reading glasses in older adults who have presbyopia.
In some cases, corneal inlay surgery can be combined with LASIK surgery to correct both presbyopia and common refractive errors (nearsightedness, farsightedness and/or astigmatism).
