Diagnosis
-non-laser refractive
-correct mild hyperopia
-help old ppl reduce their need for glasses while reading
-uses low energy to reshape the cornea and restore near vision
-hand-held instrument with a tiny probe (smaller than a human hair) applies low-level, radio frequency (RF) energy to specific spots that form a circular pattern on the outer part of the cornea
-connective tissue then shrinks where the RF energy was applied, causing the circular band to act like a belt that "tightens" and steepens the cornea -- change in the curvature of the eye's surface
-no tissue is removed from the eye during a NearVision CK procedure that takes only a few minutes
-affects distant view to a minor extent
-doctors may run a test for patients to experience the results before doctors decide whether they should take the surgery
-patient must have good distant vision and above 40 years old
-no dry eyes
-long-lasting effects, but presbyopia may worsen
Procedure
-corneal topographer will be used to create a detailed map of the curvature of your cornea
-anesthetic eye drops applied to your eyes
-small support device called a speculum used to keep your eyelids open and prevent blinking
-treatment pattern on your cornea will be imprinted, showing where the radio frequency energy should be applied
-hand-held probe then is used to deliver the energy to a specific depth within the cornea at these spots
-entire process takes a few minutes
-slight pressure may be felt
Side effects
-None which are serious
