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.

Eye doctors explain that LASIK as well as other forms of laser eye surgery are virtually painless, and typically result in an almost immediate improvement in vision, giving many even 20/20 vision or better. In many cases the primary drawback of LASIK is the slight chance of being left with uneven or thin corneal flap sides that could cause astigmatism, or an uneven corneal curve that results in blurry vision or tearing, scarring, infection or chronically dry eyes. Sometimes, people who have LASIK also can develop other issues such as seeing more glare, or halos, and even some instances of seeing double after laser eye surgery.

Laser eye surgery in the form of IntraLase Lasik, is a method in which a laser is utilized to trim the corneal flap. As with other forms of LASIK, a laser is then used to reshape the cornea. There are sveral advantages to more advanced LASIK procedures, including the ability for eye doctors to be more likely to provide patients with 20/20 vision or better with less chance for complications.

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.

The main drawback of some more advanced forms of lasik when compared to traditional LASIK, is that sometimes they cost more.Other forms of laser eye surgery include what procedures known as Wavefront or custom LASIK, which use precise, individualized 3-dimensional maps to guide the laser in re-shaping the cornea. The patients level of refractive error can be determined exactly with the help of laser eye surgery to remove the corneal tissue. Wavefront LASIK, a precision technique, will often effect a tremendous improvement in day and night vision, as compared to standard LASIK procedures. Also, there is a much less of a chance of tearing or scarring, less likelihood of infection, chronic dry eyes, and glares, and fewer chances of halos or double vision.
