PURPOSE: To evaluate the extent of intraocular lens (IOL) tilt and decentration after implantation in eyes with glaucoma. SETTING: Hayashi Eye Hospital, Fukuoka, Japan. METHODS: Fifty-two eyes of 52 patients with glaucoma and 52 control eyes from 52 age-matched patients had phacoemulsification with IOL implantation. Twenty-nine eyes had closed-angle glaucoma (CAG), and the other 23 eyes had open-angle glaucoma (OAG). The extent of IOL tilt and decentration was measured using Scheimpflug videophotography 1 week and 1, 3, 6, 9, and 12 months postoperatively. RESULTS: The mean tilt angle in the glaucoma group was significantly greater than in the control group throughout the follow-up. Mean decentration length was also greater in the glaucoma than in the control group, but the difference was not significant. The incidence of eyes showing a marked tilt (greater than 5 degrees) or decentration (greater than 0.5 mm) was higher in the glaucoma than in the control group. The mean tilt angle and the incidence of eyes showing a marked tilt or decentration in the CAG group were significantly greater than in the control group. CONCLUSION: Intraocular lens tilt was more extensive in the eyes with glaucoma, especially in those with CAG, than in normal eyes. Decentration was also greater in the glaucoma groups than in the control group, although the differences were not significant.
