Using the most advanced technology available, Custom LASIK maps individual corneas, capturing their unique features to provide the utmost precision in reshaping your corneas to correct your vision. As a result, Custom LASIK corrects a wider range of visual problems, including what is called higher order aberrations, such as halos, glare and night-vision problems, that are often not correctable with lenses.
For their Custom LASIK patients, UC Davis ophthalmologists are using the recently FDA-approved wavefront technology that tracks eye movements 4,000 times a second — 33 times faster than any other system. This gives the UC Davis laser vision correction team unmatched precision in correcting nearsightedness, farsightedness, and astigmatism, as well as the higher order aberrations. The system maps individual corneas in three dimensions capturing their unique irregularities and then transmitting the mapping directly to the excimer laser system where the map acts as a guide during surgery.
Like LASIK, recovery time is short. Since only the edge around the corneal flap needs to heal, there is rapid visual recovery and minimum discomfort. After surgery, the eye may tear for a few hours. A protective shield is worn over the eye for the first 24 hours, and there may be some temporary, mild distortion in vision for the first few days after surgery. Most patients are able to return to work the next day.
Risks are also minimal. Over- or under-correction of vision and infection may occur. In rare cases, corneal scarring may develop, and there is a chance of surgical problems related to the flap, but this, too, is very uncommon.
