LASIK Breakthrough Eye Surgery Procedure
LASIK, one of the biggest breakthroughs in eye surgery is a surgical procedure that uses non-thermal to change the shape of the cornea to improve vision. LASIK, which is actually an acronym for laser assisted in situ keratomileusis (although few people ever know), which means "reshape the cornea with a laser."
There are other types of refractive surgery procedures, but LASIK is the most advanced. While LASIK and PRK(Photorefractive keratectomy) use the same type of laser procedures are different with how the stroma, the middle layer of the cornea is exposed. In PRK, the top layer of the cornea is exposed to scrape the stromal layer, while in LASIK, a flap is cut only in the layer and then folded.
LASIK involves a two step procedure. The first step involves the creation of a micro-thin flap of corneal tissue using a microkeratome blade or disposablewith a laser, IntraLase. Throughout the procedure, a small area of the eye is affected at one end to keep it attached to the eyes. The second phase includes the folding of the flap and using an excimer laser to treat corneal tissue. The excimer laser to flatten the cornea to correct nearsightedness, farsightedness by the steeper cornea and astigmatism, which makes the cornea more symmetrical.
In addition, LASIK can also correct presbyopia, a condition that oftenoccurs with age. Presbyopia is the inability of the eye to see things clearly and to focus on close objects. LASIK, however, can correct one eye for distance vision clear and the other eye for near vision clear. This is called monovision.
The excimer laser, which is the secret behind the procedure was actually originally developed by IBM for computer chips. The technology uses a beam of cool ultraviolet light, which means that most of the heatdissipates quickly. This property makes it a very cool excimer laser is ideal for eye surgery because it can vaporize corneal tissue without damaging the eye tissue through heat.
And why was originally developed with computers in mind, the laser is extremely accurate, with an accuracy of 0.25 microns. Who is less than one thousandth of a millimeter. For most procedures, it is sufficient to remove or correct 50 microns thick, which is thicker than a human hair.
PartIt is a safe procedure, LASIK also allows a rapid visual recovery and little postoperative discomfort, unlike other types of surgery. There is a possibility even less for Haze and scarring of the cornea and changes in vision.
How "perfect" because the procedure may seem, LASIK, like any surgery, can still cause complications and may lead to different risks.
Some conditions that may occur are temporary:
1. Dry Eyes
2. SensitivityBright Lights
3. Glare or halos around bright lights
The following conditions are also possible but very rare
1. Sub-on-corrections and adjustments that need improvement, which has about 10 per cent risk
2. Wrinkled corneal flap that requires repositioning of the flap, which is extremely rare
3. Permanently blurred vision, which can be corrected with eyeglasses, contact lenses, or other improvements, and infections of the cornealeads to permanent scarring and vision disorders.
Knowledge of these conditions can occur, it is important for a person decides to undergo the procedure, he or she will consult with specialists. The doctors also provide a consensus that surgical patients must sign before proceeding.
