Intacs are micro-thin corneal implants, that can be an alternative to LASIK. An ophthalmologist inserts them under the outer edge of your cornea during a brief outpatient procedure.
Intacs corneal implants reshape the curvature of your cornea from within, to correct mild nearsightedness. Unlike laser surgery, no corneal tissue is removed from the central optical zone of your cornea. Intacs corneal implants change the curvature of your eye by adding ultra-thin ring segments, rather than removing tissue.
The only way to determine if Intacs corneal implants are right for you is to have an eye examination.
Monovision LASIK
Monovision LASIK is a technique to reduce the need for reading glasses or bifocals by using LASIK.
The need for reading glasses effects most of us after 40 when the natural lenses in our eyes lose flexibility. This condition is known as presbyopia. A sign of presbyopia is when you cannot read without holding the item far away from you. Many people have excellent vision without glasses all their lives, until ‘readers’ become necessary because of presbyopia.
Although a person aged 40 or over may not currently be having problems with presbyopia, after LASIK, some may experience the need for reading glasses due to a phenomenon called Sudden Presbyopia. Before LASIK the stiffness of the lenses was not an issue, but with the overall improvement in vision after LASIK, this situation becomes noticeable.
Monovision LASIK is one solution for presbyopia. Another is Multifocal IOLs. Monovision LASIK is very simple. One eye is corrected for near vision and the other eye is corrected for distance vision. Remarkably, the brain works out which eye to use and when, and the need for readers is reduced or eliminated. Your doctor will advise you how monovision LASIK can be of most benefit for you.
