How CK works

Conductive Keratoplasty changes how the eye focuses light by reshaping the cornea using radiofrequency (RF) energy. CK is a quick procedure with no cutting involved. You don't even have to go to an outpatient surgery center. In just three minutes, a doctor can perform CK in his or her office.

Procedure

After the doctor has applied a topical anesthetic (eye drops), controlled RF energy is applied in a circular pattern to heat and shrink the corneal tissue. This pattern is along the periphery of your cornea, which spares your visual axis (i.e., pupil) and therefore helps minimize some of the side effects associated with other refractive procedures. Once finished, you don't have to wear a patch and can usually return to work or normal activities the next day. Vision generally begins improving in about a week's time. As with other vision procedures, the level of improved vision may be temporary due to the natural aging process. While Conductive Keratoplasty can turn back the clock on your vision, it cannot stop the clock entirely.

The aging eye and reading glasses

Even if you've had great vision your whole life, by the time you hit your 40s you may find that it's increasingly difficult to read a menu, do a crossword puzzle or even see your computer screen. This condition — called presbyopia — affects most people by age 40 and virtually everyone over age 51. As the human body ages, the lens of the eye becomes less flexible and loses its ability to focus on objects by thickening or thinning itself. As a result, people with presbyopia experience blurred vision when trying to focus on objects that are up close.

NearVision CK: A safe, effective solution for presbyopic patients
NearVision CK (Conductive Keratoplasty® ) is performed using the ViewPoint™ CK System, the only technology approved by the US Food and Drug Administration (FDA) for improving near vision in patients with presbyopia.

NearVision CK improves near vision by steepening the central cornea using controlled radiofrequency (RF) energy. The RF energy is applied in a circular pattern along the periphery of the cornea, which may minimize the potential for some complications associated with other vision procedures.

In FDA clinical studies, 98%* of patients were able to read newspaper-size print without glasses (12-month follow-up data). What’s more, NearVision CK offered this improvement without affecting distance vision when using both eyes; 87% of patients could see 20/20 at distance, as well as read phonebook-size print at near. As you can see from the clinical trial information below, NearVision CK has the potential to reduce your need for reading glasses in a variety of everyday situations:

Activity	Could See Clearly Before NearVision CK Treatment (% of patients)	Could See Clearly After NearVision CK Treatment (% of patients
Read street signs	86%	100%
See computer screen	36%	90%
Read menus & golf scorecards	9%	86%
Sew, knit or do crafts	9%	81%
Read newspaper or magazine	5%	86%
