California Lasik Eye Surgery : What Is Wavefront Lasik Customization?




Our eyes have higher order aberrations that are not correctable with glasses or contact lenses. In order to resolve these higher-order aberrations that are often linked to the visual glare and halos that cause night vision problems and vision quality, Wavefront Lasik Customization can be used.

A wavefront map is used to diagnose and measure the higher order aberrations. This Wavefront map is created by bouncing harmless light rays off the patient’s retina.

Results are then fed into a complex computation program, which calculates a superior ablation profile that not only attempts to retain the natural shape of the cornea but also targets any previous aberrations within a patient’s eye.

Moreover, the higher speed laser shortens the surgery time to provide greater patient comfort and increased reliability.

A specialized laser algorithm called Optimization is then used to retain the natural shape of the patient’s cornea. By trying to keep the natural shape of the cornea, the surgeon personalizes the surgery to adjust for the natural shape, thickness, and prescription of each patient’s eye.

The benefits are as follows:

1. Improved treatment accuracy

2. Increased quality of vision

3. Reduced chance of night vision problems, such as halos




    • California Lasik Eye Surgery : Can Epi-Lasik And IntraLase Help Older People Regain Full Vision?




    A lot of people who are previously not qualified as a candidate for LASIK are able to have LASIK eye surgery now. Why is this so? Moreover, this is especially true for older people.

    This is due to the advances in LASIK technology. For instance, Linette Hwu, who has very thin corneas and very large pupils and was very nearsighted, was previously warned by doctors that she was not a candidate for LASIK surgery. However, about 4 months ago, she underwent one of the new LASIK procedures, Epi-Lasik. Epi-Lasik is designed for patients who cannot have conventional LASIK surgery as it removes too much corneal tissue. She is now able to see 20/20 without glasses.

    In addition to LASIK, PRK and Epi-Lasik, there is IntraLase, which uses a laser rather than the special blade used in LASIK to cut a flap in the cornea. This may offer improved precision and reduce side effects such as dry eye, the one complication that Ms. Hwu experienced.

    Even the U.S. military, which has previously restricted laser surgery, has embraced it now through a program called Warfighter. Doctors at Lasik Eye Surgery centers around the country, are lasering the eyes of many troops bound for Iraq and Afghanistan, where battlefield conditions make wearing glasses or contact lenses difficult.
