Finally Get Rid Of Those Reading Glasses!
No one escapes presbyopia which begins to show up around age 40 for most people. Traditional solutions for presbyopia include multifocal eyeglasses such as bifocals and trifocals, multifocal contact lenses and artificial lenses. PresbyLASIK (multifocal LASIK) is an advanced type of laser vision correcting surgery that changes the shape of the eye's cornea to create different power zones for seeing at varying distances.
How PresbyLASIK Works
Most people 40 or older can typically see well at a far distance, but require reading glasses for close work or reading fine print. Multiple or progressive reading zones can be added into the glasses they normally wear to provide the extra prescription power they need. Contact lens wearers can order bifocal or trifocal lenses that serve the same purpose as these eyeglasses, but fit over their corneas. Both solutions can be expensive and difficult to adjust to.
PresbyLASIK provides similar zones by reshaping the eye's clear surface into precise contours that alter the way light rays enter the eye. The brain is then able to select which of these zones provides the sharpest vision – whether the object is near, far or in-between. Unlike contact lenses which can cause vision distortions by moving on the surface of the eye, presbyLASIK provides fixed zones directly on the eye's surface.
