With today’s increased life expectancy, many people will spend over half their life relying on reading glasses to see objects up close. Over 60 million Americans struggle with reading glasses every day. CK can change how the eye focuses light by reshaping the surface of your cornea (the clear front surface of your eye). When the shape is changed, light can be re-focused on the retina in the back of the eye. To produce this effect, CK uses the controlled release of radiofrequency energy to shrink corneal tissue, which steepens the cornea and allows light to properly focus again. If you are over 40 years of age and wear reading glasses or are suffering from headaches after focusing on near objects, you may be a candidate for CK. Other important criteria include: no significant changes in your vision for one year, no chronic eye disorders, no pregnancy within the past 6 months, and no chronic illness or disease.
