Conductive keratoplasty

Conductive keratoplasty (CK) is a type of refractive surgery that uses radio waves to adjust the contour of the cornea by shrinking the corneal collagen around it.[1] It is used to treat mild to moderate hyperopia. It is a non-invasive alternative to other types of eye surgery. It uses the same principles of laser thermokeratoplasty (LTK) and radial keratocoagulation, although the former uses holmium laser and the latter a 700° Celsius needle to correct hyperopia.[2]
