Introduction To NearVision CK

Conductive Keratoplasy is a procedure developed to treat farsightedness or HYPEROPIA. Hyperopia is an eye condition that causes blurry vision because the cornea and crystalline lens of the eye focus light rays from distance and near objects behind the retina (back of the eye). This may occur at any age, but usually occurs in early adulthood. At first, the blurry vision may be more noticeable at near than at distance, but over time and with aging, it may affect both distance and near. This condition is the opposite of nearsightedness or MYOPIA where the light rays are focused by the eye structures in front of the retina and typically the vision is worse at distance than near.

Hyperopia is usually progressive with age. Over time, the amount of hyperopia usually increases which requires stronger and thicker glasses. Hyperopia should not be confused with PRESBYOPIA which is often referred to as over 40 vision. Presbyopia affects near vision activities in most every adult over age 40. When hyperopia and presbyopia coexist in an early 40s adult, then both distance and near vision are blurry. Presbyopia is also progressive with age, but tends to stabilize in a person's early 60s.

For those individuals who choose to attempt to eliminate or reduce dependency on corrective lenses, there are kerato-refractive procedures to assist with this effort. Both Laser Vision Correction (excimer laser) and Conductive Keratoplasty (CK) are FDA approved for the treatment of hyperopia. Dr. Jaben usually chooses excimer laser, either LASIK or EpiLASIK, rather than CK for the treatment of hyperopia because the excimer laser has proven to be more effective and longer lasting for this condition, especially for higher amounts of refractive error (corrective lenses).

However, at this time, CK is the first and only procedure which is FDA approved for the treatment of pure presbyopia (with only minimal hyperopia or myopia); this procedure has been termed NEARVISION CONDUCTIVE KERATOPLASTY and goes by the name NearVisionCK. This technique does not actually correct or cure the presbyopia problem; there is presently no procedure which will prevent or cure presbyopia in humans. However, NearVisionCK does allow one to have "vision for daily life" without glasses for most normal daily activities. It is essentially like "turning back the clock" on your eyes to the days in your early 40s before presbyopic symptoms occurred. It may not eliminate reading glasses completely and forever for seeing very small print or for prolonged reading, but it can help you see your watch, apply makeup, view your car dashboard or golf scorecard without interfering with distance vision. After NearVisionCK, most people are able to function almost entirely without dependency on glasses. Additional treatments later in life for dealing with the natural presbyopic progression may be needed every few years.

So if you answer the following three questions YES:

(1) Are you 45 years of age or older?
(2) Do you have good vision at distance without the aid of corrective lenses (glasses or contact lenses) in both eyes?
(3) Are you tired of your reading glasses, and interested and motivated to eliminate or reduce your dependency on glasses for near vision activities?

THEN you may be a candidate for NearVisionCK and should follow the instructions on this website for contacting Dr. Scott Jaben for a NearVisionCK evaluation.
