Any person's vision problems are generated by small "aberrations" within the eye that prevents the light from focusing objects as they should. The Lasik equipment locates and classifies these aberrations and then processes them so that the Lasik physician will correct these and allow the light to focus properly.

In a Wavefront Lasik (CustomVue) procedure, the patient stares at one point while a light is sent into the eye, which is reflected back and read by a Wavefront sensor. The distortions in this reflected light are mapped using a small computer within the CustomVue system (Wavescan), and then this information is used to guide the laser that treats the eye.

Once the light creates the map for the eye, the Lasik surgeon has to create a small flap to access the cornea. This flap is then opened to allow the cornea to be reshaped by the Lasik system. The excimer laser actually reshapes the cornea, which is the crucial part of the Lasik procedure. In order to determine exactly how to reshape it, the map created earlier by the Wavefront sensor is used to direct the beam of light accurately. The Lasik physician uses these precise tools to get the clearest vision results possible.

This custom Lasik procedure can not only correct standard problems as nearsightedness (Myopia or minus number), long sightedness (Hyperopia or plus number), Cylindrical number (Astigmatism or cylinder) and reading glasses after 40 years (Presbyopia) but can also address aberrations that create light halos, glare, haze or starburst patterns. Once the Lasik physician determines that all relevant aberrations have been eliminated, he replaces the flap in its proper position, where it adheres normally and will heal naturally within seconds.

As mentioned earlier, this entire Lasik process takes between one to one and half minutes per eye. A patient gets eye numbing drops to make the procedure both relaxing and painless. Most people notice an improvement in vision due to Lasik almost immediately.

Once the Lasik procedure is finished, you will get some eye drop medication to lubricate and protect your eyes. This medication (and the liquid in the drops themselves) may cause some blurring and so for this reason (and to avoid any eyestrain) you should arrange for someone else to drive you home. It is also a good idea to go to sleep as soon as possible after the Lasik operation in order to promote even faster healing.

To promote optimal healing it is advisable to wear sunglasses / glares over your eyes for 2 days. Follow closely any recommendations by the Lasik physician. Do further investigation into this great CustomVue Lasik procedure and get a clearer focus on your future!
