Abstract:
PURPOSE: To evaluate the accuracy of Pentacam(R) built-in 5 intraocular pressure (IOP) correction programs used to measure the IOP of patients who received corneal refractive surgery. METHODS: IOP of 124 eyes from 62 patients who underwent epipolis laser in situ keratomileusis was measured with Goldmann applanation tonometry (GAT) at 6 months pre- and post-operatively. The collected data was input into Pentacam(R), calculated by 5 correction programs, Ehlers, Shah, Dresden, Orssengo / Pye, Kohlhaas, and compared. RESULTS: The GAT-based pre- and post-operative IOP was 15.75 +/- 2.24 mm Hg, and 10.72 +/- 2.31 mm Hg, respectively, revealing the post-operative IOP to be significantly lower than the pre-operative IOP (p < 0.001). Among the 5 correction programs within Pentacam(R), Ehlers program showed little difference between pre- and post-operative IOP values (p = 0.228) and the post-operative correction value showed no significant difference with the pre-operative GAT value (p = 0.413). CONCLUSIONS: The Ehlers program is the most accurate among the 5 Pentacam(R) correction programs evaluated in the present study, and can be a useful tool for correcting the true IOP of patients which tends to be higher after corneal refractive surgery.
