| Abstract |
PURPOSE
To compare pupil size measured by Colvard(R)pupillometer, ORBScan II(R), Sirius(R) and analyze correlation between pupil size and night vision disturbance after refractive surgery according to measuring methods. METHODS: Two hundred eyes of one hundred patients who underwent refractive surgery were retrospectively evaluated. Pupil size was measured with Colvard(R)pupillometer, Sirius(R) in the scotopic light condition and with ORBScan II(R), Sirius(R) in the photopic light condition. Patients filled out questionnaire about night vision disturbance at postoperative three months. Correlation between pupil size according to measuring methods and night vision disturbance was evaluated. RESULTS: The mean age of patient was 26 years and number of male patients was 36. In scotopic light condition, pupil size measured with Colvard(R)pupillometer (6.76 mm) was significantly larger than that of Sirius(R) (6.53 mm) (p < 0.001). In photopic light condition, pupil size measured with ORBScan II(R) (3.98 mm) was significantly smaller than that of Sirius(R) (4.41 mm) (p < 0.001). Night vision disturbance were correlated with pupil size and Sirius(R) in the scotopic light condition had strongest correlation among three measuring method (r = 0.44). CONCLUSIONS: Sirius(R) tends to measure pupil size smaller than Colvard(R)pupillometer in the scotopic light condition. The correlation between night vision disturbance and pupil size was highest in Sirius(R). |
