Question by Food for Thought: How many different types of Lasik are there?
I only thought there was one. How many are there and how are they different? Which one entails the least pain and which one takes the least amount of time to heal? I'm 17 and i'm getting it done when i'm 18. I don't want my senior year to suck or be delayed because i can't see or anything.

Doctors perform Lasik surgery with different kinds of Lasik lasers. Depending on the medical profile of your eyes, one kind could be better for you than the others may. However, the degree of results rests on the skill and experience of your doctor.Doctors perform Lasik with excimer lasers.

The common Lasik Lasers in use today are:

1. Slit scanning lasers, which have small beams. The beam comes from slits of variable sizes on a rotating device

2. Spot scanning lasers, which remove tissue from the cornea with a beam of small diameter. This is the most commonly used laser

3. Wavefront-guided lasers, which use a special device to scan defects in the eye. The device does this by tracking the path of light through the eye.

One difference in these lasik lasers is the speed with which they remove corneal tissue. They can take anything between 30 and 60 seconds or more to do the job. The other difference is in the laser beam’s diameter. Patients with larger pupils need lasers of appropriate diameter.

Lasik laser equipment comes in different configurations to suit every kind of Lasik surgery. Surgeons use some machines to correct myopia, or nearsightedness. Hyperopia or farsightedness calls for different equipment. Certain lasers are most suitable to correct astigmatism, a condition that causes distortion of the visual image on the retina because of irregularities in the cornea.

All the latest Lasik laser machines feature automated eye-tracking systems. These systems keep the laser directed on the target area. They have increased Lasik’s overall success rate considerably since their introduction.
