Technology...technology...what term runs hand in hand with the word technology? Let's just say Laser. Laser is a symbol of the days of the future. We see laser at work in cars, computers, weapons, ect. We are just beginning the future...
Laser technology has made its mark in the optical field, curing thousands and maybe millions of people from poor vision. Imagine waking up the next day without having to put glasses on or clean some contacts to fit them in the eyes. With laser, it can now be possible. Many attempts have been made while perfecting the use of laser, including another type of laser surgery called PRK (photo refractive keratectomy). PRK mainly involved making radial incisions at the edges of the cornea to flatten it, and thereby, improving vision. This section will focus only on LASIK eye surgery, the latest brand of laser eye surgery. LASIK eye surgery tops the scale in terms of cost beyond any other eye correction methods.

The Process

The process is quite rapid, with quick results. To sum the process up, a device called a microkeratome is used to slice a piece of the cornea and peel it down, exposing corneal surface. The laser then goes in and makes the necessary trimming to correct the cornea's focusing abilities. The flap is folded back into position and that ends the surgery.
| 1. | when you walk into the office, you will be asked to sit in a chair similar to a dentist's chair. | |
| 2. | drops are used to numb the eye so that it does not move during the corneal slice. | |
| 2. | a lid speculum covers the eye so that the corneal slicer can have the correct alignment. | |
| 3. | a suction ring is applied on top of the cornea to prevent further movement. | |
| 4. | the eye pressure is checked. if the pressure does not land within acceptable range, the corneal flap may not be of desired cut. | |
| 5. | the microkeratome goes into the suction ring and makes the slice of the cornea. | |
| 6. | the cornea is peeled back | |
| 7. | a laser is applied to the eye and the reshaping of the cornea begins | |
| 8. | after the laser is done, all the equipment is removed and excess tissue around the cornea is removed. | |
It seems like a simple process right now, but you have to go through many tests and procedures before becoming a candidate.
