Abstract:
We investigated mean keratometric vale(K) after penetrating keratoplasty(PKP) and analyzed the factors which affected the postoperative mean K. We obtained mean K at postoperative 3 months in the 65 eyes of 65 patients which PKP of PKP combined with intraocular lens(IOL) implantation was done, and analyzed those values according to sex, age, preoperative diagnosis, preoperative corneal neovascularization, methods of trephination, methods of suture and methods of operation. The postoperative mean K of all patients was 42.83 diopters(D) and 43.32D in the recipient cornea without neovascularizaion, 42.51D with neovascularization, 42.72D in the cases of hand-held trephination and 43.27D in Hessvurg-Varron trephination, which had no statistical significant difference between K and sex, age, preoperative diagnosis, methods of suture, and methods of operation. This results will be helpful to predict the change of K ofter PKP, and give a better refractive results to use the operator's own mean K for the IOL calculation in the case of PKP comvined with IOL implantation.
