The course of the contractive forces during and after heating is a complicated function of the spatial time/temperature profile. Laser thermokeratoplasty lesions produced with 2 irradiation times showed different stages of denaturation and induced refractive change.

CPC is an effective procedure for surgical reduction of intraocular pressure. The initial pressure-reducing effect of CPC was not related to the type of glaucoma. The individual predictability of the effect of CPC, however, is difficult because of the high interindividual differences. The rate of complications is low.
