Custom LASIK eye surgery or Wavefront Guided LASIK eye surgery

Custom LASIK eye surgery, also known as Wavefront Guided LASIK eye surgery, has become a significant surgical technique in corrective eye surgery.

Custom LASIK eye surgery – the procedure

This development in Lasik technology utilises equipment that is capable of taking many more precise measurements of the eye than traditional Lasik procedures. A ray of light is projected into the eye. It is reflected off the retina and out through the pupil. The reflected light is captured and interpreted by the surgeon with a 3-D Wavefront map. The surgeon then applies these 3-dimensional measurements to understand precisely how your eye processes images. He then uses those measurements to calculate how best to use the laser in reshaping the cornea.     

The enhanced benefit of this technique is that more precise measurements enable the surgeon to use Custom LASIK eye surgery to customize the surgery to your eye to a much greater degree than is possible with the traditional Lasik procedure. It may be possible to correct vision problems with this customized eye surgery that glasses and other forms of corrective eye surgery will not correct.

Another benefit of this particular technique is the use of a much faster laser. This type of laser is able to keep pace with the uncontrollable and rapid eye movements that your eye normally makes (saccadic eye movements), resulting in more precise measurement and significantly reduce the likelihood of side-effects.

Custom LASIK eye surgery – aberrations

The Wavefront technique measures the optical imperfections of your eye which are called ‘wave aberrations’. There are two types of visual aberrations:

§ - High-level aberrations - create problems with glare, contrast sensitivity, problems seeing at night, halos and shadows.

§ - Lower forms of aberrations - are common refractive errors such as myopia, hyperopia, and mild astigmatism.

This Custom LASIK eye surgery will treat both higher and lower forms of aberrations.

Not everyone agrees that customized LASIK has been proven to correct all higher-order aberrations. In any refractive surgery there is a possibility that your higher order aberrations may get worse after surgery. It is important to appreciate there is always a risk when having any surgical procedure.

Custom LASIK eye surgery – possible advantages

You must adopt realistic expectations when embarking upon any form of surgery. What are the advantages to Custom LASIK or Wavefront LASIK ? We have listed below a number of claims made by advocates of Custom LASIK or Wavefront LASIK procedures:

§ - increased visual quality and contrast sensitivity

§ - a greater chance of having 20/20 vision or better

§ - less night-vision problems like halos and glare

§ - improved sensitivity and finer detailed vision

§ - Custom LASIK eye surgery may be the answer for people who can not benefit from other forms of corrective eye surgery

§ - Patients who had Wavefront LASIK showed an 88% improvement in their vision whereas, patients who chose traditional LASIK eye surgery showed only a 40% improvement in their vision

§ - Wavefront LASIK may improve eyesight for patients with a high astigmatism.

This appears to be wonderful news for patients who have been told that corrective surgery would not improve their eye problems.
