title: Comparative analysis of intraocular lens power calculation methods after excimer laser surgery.
abstract: Many methods have been used in an attempt to more accurate predict the intraocular lens (IOL) power in the eyes undergoing refractive surgery, but none has proved most accurate. The aim of this study was to evaluate the accuracy and predictability of different IOL power calculation methods in eyes after excimer laser surgery. The outcomes of phacoemulsification and IOL implantation in 18 eyes of 16 patients with prior excimer laser keratectomy were documented. The lowest error was achieved using history-derived method. The refractive results of IOL implantation using the same biometry data in eyes after excimer laser surgery can vary markedly. In the present study, the SRK-T formula resulted in highest accuracy.
