NearVision CK® also known as Conductive Keratoplasty is a promising option for patients with farsightedness or presbyopia. This is a revolutionary vision correction procedure that uses radio-frequency (RF) waves instead of a laser to reshape the curvature of your eye. By changing the way your cornea directs light to the rest of your eye CK effectively treats the conditions known as hyperopia or presbyopia. CK involves no cutting of the eye whatsoever.
This new NearVision CK® procedure uses very accurate pulses of radio-frequency waves to reshape and steepen corneal tissue centrally, resulting in improved vision, especially for reading. Radio frequency is one of the modern medical world’s most advanced surgical technologies. It is routinely used in other procedures such as prostate cancer therapy, orthopedic surgery, and cardiovascular procedures.
The NearVison CK® procedure is performed using a small probe, thinner than a strand of human hair, that releases radio-frequency (RF) energy. Instead of a scalpel or a laser, CK releases radio-frequency energy through a probe as thin as a strand of human hair, without cutting or removing tissue. The entire NearVision CK®. Procedure takes about five minutes to complete. After application of a topical anesthetic, radio-frequency energy is applied in a circular pattern to shrink small areas of corneal tissue. This circular shrinkage pattern creates a constrictive band (like the tightening of a belt), increasing the overall curvature of the cornea. The result is somewhat like wearing a bifocal contact lens.
The entire CK procedure takes about five minutes, and most patients report immediate positive results after NearVision CK®. After this type of eye surgery, there may be some mild discomfort, which can be alleviated with drops. Shortly after having the NearVision CK® procedure patients will have better ability to focus on near objects without any drastic effect on distance vision. Patients should be advised that that complete vision correction may take several weeks to manifest itself.
The doctors and staff at the Texas Eye Institute will be very careful when selecting patients for this procedure. We welcome you to contact us for the candidacy specifications. Not everyone is a candidate for NearVision CK®. Your vision correction specialist will conduct a series of diagnostic tests to determine if CK could help. NearVision CK® candidates are typically:
