Candidates for Conductive Keratoplasty

FDA approved for temporary hyperopic correction (farsightedness)
Good Candidates

• +0.75 to +3.25 diopters of hyperopia
• Less than 0.75 diopters of astigmatism
• Age 40 or older
  

FDA approved for temporary correction of presbyopia (near vision).
This is NearVision CK. Good Candidates

• Minimal or no distance correction required
• Currently use glasses just for near vision tasks
• Age 40 or older

	Using a probe thinner than a strand of human hair, radio waves are applied in a circular pattern to shrink small areas of corneal tissue
	The circular treatment pattern acts like a belt tightening around the cornea, increasing its overall curvature to correct farsightedness.

Although the goal of CK is to improve vision to the point of not being dependent on glasses or contact lenses, or to the point of wearing thinner (or weaker) glasses, this result is not guaranteed.

Dr. Leahey and Dr. O'Brien uses a device known as the Viewpoint CK System to perform CK. CK is one of a number of alternatives for correcting farsightedness. The CK treatment utilizes a controlled release of radiofrequency (RF) energy to increase the temperature of corneal tissue. The treatment is applied with a probe that is introduced 8 to 32 times into the cornea in a circular pattern, which results in an increased curvature of the cornea to correct your vision. The correction you achieve from CK may be temporary. The surgery is performed using a topical anesthetic (drops in the eye) under a microscope. Due to the use of anesthetic drops, there is expected to be little to no pain or discomfort during this procedure.
