ABSTRACT

A. HYPEROPIA CORRECTION BY CONDUCTIVE KERATOPLASTY 1. Thermokeratoplasty Procedures Surgical correction of hyperopia has been a greater challenge to ophthalmology than the correction of myopia. Attempts to steepen the central cornea by non-ablative methods, such as thermal keratoplasty, date back to the rabbit studies by Lans in the nineteenth a technique developed in the

Soviet Union, was used to produce thermal burns (up to 600C) that penetrated to 95% of corneal depth (1). Studies showed substantial overcorrection followed by marked regression (2-4). Evaluation of the procedure through well-designed clinical trials before adoption and dissemination was recommended (5).
