목적: 백내장안, 인공수정체안, 각막굴절교정수술안에서 OcuScan^ⓇRxP, LENSTAR^Ⓡ, IOL Master^Ⓡ로 측정한 생체계측의 재현성, 반복 성을 비교하고, 백내장수술 후 굴절력예측의 정확성을 비교하고자 하였다. 대상과 방법: 백내장 45안, 인공수정체 31안, 각막굴절교정수술을 받은 32안을 대상으로 하였다. 각 대상군 별로 세 기기를 이용하여 계측하였다. 결과: 모든 군에서 기기에 따른 유의한 안축장의 차이는 없었고, 재현성 차이는 없었다. 모든 군에서 기기별 상대적 반복성은 모두 1.5% 이하였다. 백내장 수술 후 굴절력예측에서 기기에 따른 유의한 예측오차는 없었다. 수정체혼탁이 심하여 IOL Master^Ⓡ로 생체계 측이 되지 않은 경우는 LENSTAR^Ⓡ로도 계측되지 않았다. 결론: 모든 군에서 세 기기로 측정된 안축장의 재현성과 굴절력예측은 유의한 차이가 없었고 반복성은 초음파를 이용하는 방법이 높았 지만 세 기기 모두 좋은 반복성을 보였다. IOL Master^Ⓡ보다 긴 파장을 이용하는 LENSTAR^Ⓡ도 수정체혼탁이 심한 경우는 생체계측이 불가능하였다.

Abstract

Purpose: To evaluate the reproducibility and repeatibility of biometry in cataractous eyes, pseudophakic eyes and eyes having undergone refractive surgery. The OcuScan^®RxP, LENSTAR^® and IOL Master^® instruments were compared, as were. The accuracies of the refractive results after cataract surgery. Methods: The biometries of 45 cataractous eyes, 31 pseudophakic eyes, and 32 eyes having undergone refractive surgery were measured by two practitioners using OcuScan^®RxP, LENSTAR^® and IOL Master^® instruments. The paired t-test was used to compare the reproducibilities in the three groups. Results: There were no differences in axial length among the groups when using any of the instruments. There was no significant difference in the repeatibility regardless of the instrument used, although. In the cataractous eyes, pseudophakic eyes and eyes with refractive surgery, OcuScan^®RxP showed the highest repeatability. However, we knew that all three instruments were excellent in the repeatability because the difference was less than 1.5%. The Prediction error of the instruments with regard to refractive results could not be determined after cataract surgery. In some patients with severe cataract, measurement was impossible for both the LENSTAR^® and IOL Master^® instruments. Conclusions: In all groups, OcuScan^®RxP, LENSTAR^® and IOL Master^® showed no significant differences with regard to reproducibility or prediction of refractive power after surgery. Among three groups, the repeatability was rather high in the existing ultrasound method than in the partial coherence interferometers. In some patients with severe cataract, measurement was impossible for both the LENSTAR^® and IOL Master^® instruments.
