Different forms of Laser Eye Surgery - LASIK and Better Vision
To improve vision, many choose laser eye surgery, LASIK or another form of laser eye surgery. Patients who wear corrective eyeglasses often consider undergoing laser-assisted in-situ keratomileusis (LASIK), which is a refractive eye surgery. During this procedure the eye surgeon uses a laser to reshape the cornea. During this form of laser eye surgery, an eye surgeon uses a metal tool called a microkeratome to cut a flap on the surface of the cornea. The cornea is reshaped by eye surgeons, using a laser. Afterward the corneal flap will then be put back into place for healing.
LASIK laser eye surgery procedures will typically immediately improve vision, and are almost entirely painless. For lots of people, this gives them 20/20 or better vision. The major pitfalls of LASIK procedures include: the danger of thin or uneven corneal flap edges that might cause astigmatism or blurry vision because of an uneven corneal curve, tearing, or scarring; and the danger of acquiring an infection or developing chronic dry eye. In rare instances, those who choose laser eye surgery or LASIK develop halos,or experieince glare, or have double vision after eye surgery. Traditional lasik is often not the best procedure for people with very thin corneas, however other laser eye surgery procedures may be appropriate for these patients.
Instead of a microkeratome, IntraLase Lasik is a technique that involves using a laser to cut the corneal flap. As with standard LASIK, an excimer laser is then used to remove and reshape the cornea.
IntraLase or iLASIK procedure hav several advantages over other types of laser eye surgeries. The lasers used typically allow for more even corneal flaps to be made, allowing for thicker vertical edges which reduce the chances that patients will experience tearing, scarring or post surgery astigmatism.
Custom LASIK surgery, can be described as the use of 3-D maps, by eye doctors, to actually guide the laser while reshaping the cornea, which enables the eye surgeon to more precisely determine their patients visual acuity.
