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.{{Cite web|url=https://eyewiki.aao.org/Conductive_Keratoplasty|title=Conductive Keratoplasty - EyeWiki|website=eyewiki.aao.org}} 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°C needle to correct hyperopia.{{Cite journal | pmid = 8499365| year = 1993| last1 = Thompson| first1 = V.
