PURPOSE: To assess intraocular pressure (IOP) measured with a Goldmann tonometer over a period of one year after implantation of a Worst-Fechner anterior chamber phakic intraocular lens to correct myopia of -7.00 D or more. METHODS: The authors performed a prospective, nonmasked study of 100 patients (100 myopic eyes) who had a Worst-Fechner phakic intraocular lens implanted to correct myopia of -7.00 D or greater. Central corneal Goldmann tonometry was performed before surgery and one, three, six, and 12 months after surgery. The influence of different variables was assessed. RESULTS: IOP showed a significant increase of a mean 2.1 mmHg at three months after surgery (p = 0.001). There was not a statistically significant difference between IOP before surgery and six months after PIOL implantation (p = 0.244) or one year after surgery (p = 0.845). In one eye, the lens was explanted 11 months after surgery because of the presence of ocular hypertension. No variables studied showed a statistically significant difference from before to after surgery. CONCLUSIONS: Worst-Fechner anterior chamber phakic intraocular lens implantation led to a slight transitory increase of IOP during the first three months after surgery, but returned to preoperative levels by six months after implantation.
