LASIK is a surgical procedure that has changed the lives of many people in need of vision correction. LASIK actually stands for Laser-Assisted In Situ Keratomileusis and permanently changes the shape of the cornea, which is the clear covering of the front of the eye. LASIK, in the past, used a surgical blade called a microkeratome to cut the flap in the cornea. But with advanced technology, the procedure has changed quite drastically, and now there is blade-free LASIK surgery.
Choosing to have LASIK surgery for vision correction is not the same as it was ten years ago. At that time, the options for LASIK surgery were not very extensive. There was really only way LASIK was performed and that involved a small mechanical blade called a microkeratome being used to create a flap on the cornea, after which a conventional excimer laser was used to reshape the tissue underneath so that the cornea would be able to focus light directly on the retina. Now, technology is much more advanced, and options for vision correction surgery are more numerous.
IntraLase Method of Vision Correction
The IntraLase Method of LASIK surgery is becoming very popular with patients and eye care professionals alike. The IntraLase Method is also known as "All laser LASIK" because instead of using the microkeratome to create the corneal flap, the eye care professional uses the IntraLase laser.
The Procedure
The first step in any LASIK procedure is creating the corneal flap. Correcting your vision actually involves working with the corneal tissue that's just beneath the surface of the cornea. Access to this tissue is created by making a surface flap and folding it back. Creation of the flap is crucial to the success of your surgery. The flap must be the exact correct thickness and in the exact right place. After the LASIK procedure is finished, the flap is folded back into its position and acts as a bandage of the surgical area.
Complications during LASIK are very rare, but when there is a complication, it frequently results from a poorly created corneal flap. Using the IntraLase Laser instead of the microkeratome reduces the chance of any complications.
The IntraLase laser works by emitting quick little bursts of light that shine through the eyes' surface to a predetermined microscopic depth. Each pulse of light creates a bubble below the surface, and the bubbles accumulate to cover the entire treatment area. Your surgeon will separate the corneal tissue and fold the flap back out so your LASIK treatment can be finished.
IntraLase Advantages
Patients and eye care professionals have found the advantages to IntraLase Laser surgery to be numerous:
· IntraLase creates a very smooth surface for the laser to work on whereas the microkeratome moving back and forth creates a roughened surface.
· The blade-free approach allows for more precise customizing of the corneal flap, which allows you to achieve the desired LASIK result.
· People with thin corneas are not good candidates for traditional LASIK surgery. The IntraLase laser is more precise than the microkeratome.
· After IntraLase laser surgery, the corneal flap settles back into position more smoothly and typically heals with no wrinkles or other complications.
· IntraLasik allows more people to achieve 20/20 vision than previous methods.
· Patients experience less trouble seeing in dim lighting conditions with IntraLase Laser.
More than 600,000 procedures have been performed safely and effectively using the IntraLase Laser Method. The process is not painful and the results are excellent. In a clinical survey of LASIK patients who had their corneal flaps created using a microkeratome in one eye and the IntraLase Method in the other eye, the vision in the IntraLase eye was preferred 3-to-1.

The Eyes Have It With Wavefront Lasik
Most people around the world today are familiar with the term Lasik (Laser-Assisted in Situ Keratomileusis) and know that it is some kind of vision correction surgery. However, many people don't know that this specialized method of correcting vision with the use of a laser light uses different methods to achieve those goals.
For example, there is a method called Lasik, Epi-Lasik and Wavefront Lasik. While they all employ the use of the laser light beam to correct curvature of the cornea to improve eyesight, many people don't understand the difference. Wavefront Lasik is also known as custom Lasik. It utilizes the use of three-dimensional measurements that show doctors how your individual eye processes images. Those measurements are imported into a computer system that guides the laser to reshape the front of your eye, or cornea.
The Wavefront Lasik method uses the three-dimensional map that is created to seek out and find every little nuance that makes your eyesight what it is. While you may be farsighted, another person who is farsighted may have different degrees of the condition than you, as well as accompanying factors. Wavefront Lasik enables each individual to receive specialized surgery to correct unique vision problems that are independent of everyone else's.
This surgical method offers an increase in not only how much a person can see, but how well you can see, taking into consideration depth, peripheral vision and contrast sensitivity and contrast details as well. This surgery reduces the effect of post-operative halos and sensitivity to glare as well as increasing night vision acuity.
Wavefront is a new method of Lasik surgery that allows surgeons to provide extremely precise improvements to the shape of the cornea, which allows your eyes to better adjust and see near and far objects as well as improving depth and clarity. Such beneficial outcomes are not possible with the traditional use of eyeglasses or contact lenses, nor original forms of Lasik eye surgery.
Wavefront Lasik is recommended for people with astigmatism, myopia and hyperopia in degrees ranging from mild to moderate. While traditional vision correction methods such as eyeglasses and contact lenses can correct some problems, additional irregularities sometimes prevent optimal vision correction by these methods. Wavefront Lasik is able to not only perform the basic corrections, but also to enhance visual acuity, without cutting into the surface of the eye or requiring lengthy recovery time.
If you're looking for a Lasik procedure, wait until you visit your eye doctor to discuss which method of Lasik he or she suggests for your vision correction problems. While Wavefront is capable of treating multiple vision issues, since the surgery is so individualized, you may have one or even several options open to you. Any kind of Lasik eye surgery is expensive, so make sure you get more than one professional consultation if possible to determine which course of treatment is best for your situation. Plan on spending at least $1,500 per eye for any kind of Lasik treatment, and ask if your vision insurance plan will help pick up a portion of the tab.
Wavefront Lasik is capable of increasing and improving eyesight in most candidates for the surgery, but always remember that your eyes are irreplaceable and care and caution must be practiced to ensure that you find the best Lasik method to suit your needs.
