Wavefront Treatment Sacramento California Custom Lasik

LASIK is now the vision correction procedure of choice for many ophthalmologists worldwide. Instead of removing the surface epithelium with the laser and exposing many nerve endings (as in PRK), the surgeon performing LASIK uses a motor-powered microkeratome to create a "flap." The flap is then lifted and reflected back, allowing a computer guided Excimer laser (cold laser) to use light pulses to remodel the corneal tissue underneath. Afterward, the flap is gently positioned back onto the cornea. Since this procedure is less traumatic to the outer surface of the eye, vision is restored more quickly and the patient's discomfort is reduced. Most patients report greater comfort after surgery and can generally drive two to three days after the surgery.

Blurred vision can result from basic imperfections of the eyes’ focusing system known as lower order aberrations and from more complex imperfections known as higher order aberrations. In the past, doctors have been limited to the diagnosis and treatment of only lower order aberrations; these include nearsightedness, farsightedness and astigmatism. Higher order aberrations result in visual symptoms such as, starbursts, halos and glare around lights. These symptoms contribute to blurred vision and until recently have gone unaddressed.

Every eye has a combination of these lower order and higher order aberrations. Your eyes and your vision are as unique to you as your fingerprints and no two people are alike. Yet until recently, two people with the same prescription would be treated the same, that is because glasses, contact lenses and conventional laser surgery only address lower order aberrations, they do not address the higher order aberrations which makes every eye unique.

Now, an advanced form of laser vision correction, known as wavefront or custom LASIK takes both lower and higher order aberrations into consideration and delivers treatment based on each eyes unique vision finger print. In addition to correction of lower order aberrations the custom LASIK procedure can help improve satisfaction with night vision by reducing glare, halos and starbursts.

This procedure is the most advanced form of laser vision correction available today; capable of delivering improved vision by addressing the higher order aberrations that glasses and contacts can not correct.
