Abstract
To determine whether hyperopic laser in situ keratomileusis (H-LASIK) affects Goldmann applanation tonometry measurements. Retrospective, comparative, self-controlled case series. One hundred eight eyes of 58 patients were enrolled in the study. Baseline intraocular pressure (IOP) was measured by Goldmann applanation tonometry. These readings were compared with readings obtained at least 6 months after surgery. After H-LASIK, a decrease was observed in the measured IOP of treated eyes that could not be related to the degree of hyperopia treated or to the treatment zone diameter. A significant difference was observed between the IOP before and after surgery (P < 0.00001). The applanation tonometer underestimates the true IOP after LASIK for hyperopia.
