목적: Colvard와 ORBScanⅡ, Sirius 세 장비로 측정한 동공크기를 비교하고, 굴절교정수술 후 야간시력불편함과 동공크기의 상관관계를비교하였다. 대상과 방법: 굴절교정수술 전 Colvard, Sirius, ORBScanⅡ로 동공크기를 측정한 환자 100명 200안의 의무기록을 후향분석하였다. 암순응 상태의 동공크기는 Colvard와 Sirius를, 명순응 상태의 동공크기는 ORBScanⅡ과 Sirius를 비교하였다. 수술 3개월 후 야간시력불편함 정도를 설문조사하여 동공크기와의 상관관계를 검사방법에 따라 비교하였다. 결과: 암순응 상태의 동공크기는 Colvard 6.76 mm로 Sirius 6.53 mm 보다 유의하게 크게(p＜0.001), 명순응 상태의 동공크기는 ORBScanⅡ3.98 mm가 Sirius 4.41 mm 보다 유의하게 작게 측정되었다(p＜0.001). 술 후 야간시력불편함은 동공크기에 유의한 영향을 받으며,암순응 상태에서 Sirius로 측정한 동공크기가 가장 상관관계가 높았다(r=0.44). 결론: Sirius로 측정한 암순응 상태의 동공크기는 Colvard의 값보다 작게 측정되는 경향이 있었으나, 굴절교정수술 후 야간시력불편함과 가장 높은 상관 관계를 보였다.
Abstract
Purpose: To compare pupil size measured by Colvard®pupillometer, ORBScan II®, Sirius® 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®pupillometer, Sirius® in the scotopic light condition and with ORBScan II®, Sirius®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®pupillometer (6.76 mm) was significantly larger than that of Sirius® (6.53 mm) (p < 0.001). In photopic light condition, pupil size measured with ORBScan II® (3.98 mm) was significantly smaller than that of Sirius® (4.41mm) (p < 0.001). Night vision disturbance were correlated with pupil size and Sirius® in the scotopic light condition had strongest correlation among three measuring method (r = 0.44). Conclusions: Sirius® tends to measure pupil size smaller than Colvard®pupillometer in the scotopic light condition. The correlation between night vision disturbance and pupil size was highest in Sirius®.
