- Abstract
- 목적: Galilei G6®와 IOL master®를 이용하여 백내장 안에서 측정한 생체계측값 및 백내장 수술 후 굴절률 예측의 정확성을 비교하고자 하였다.
대상과 방법: 백내장 수술을 시행 받은 50명 50안을 대상으로 Galilei G6®, IOL master®를 이용하여 수술 전 안축장, 전방깊이, 각막굴절력을 측정하였다. 인공수정체의 도수결정은 SRK/T 공식을 이용했으며, 백내장 수술 4-6주 후 자동굴절검사계로 측정한 굴절값에서 예상 굴절력을 뺀 차이의 절대값을 이용해서 평균절대오차를 비교하였다.
결과: Galilei G6®와 IOL master®에서 측정된 안축장의 평균은 각각 23.36 ± 0.80 mm, 23.36 ± 0.90 mm였으며 통계적으로 유의한차이가 없었다(p=0.321). Galilei G6®와 IOL master®에서 측정된 전방깊이는 각각 3.22 ± 0.35 mm, 3.11 ± 0.46 mm (p<0.001),구면대응각막굴절률은 각각 44.29 ± 1.40D, 44.39 ± 1.41D (p=0.028)로 전방깊이, 구면대응각막굴절률 모두 유의한 차이를 보였다.
IOL master®와 비교한 Galilei G6®에서의 절대값 예측오차의 평균은 통계적으로 유의한 차이가 없었다(p=0.423).
결론: Galilei G6®와 IOL master®를 이용한 안구생체계측 측정치 중 안축장 길이는 유사한 결과값을 보였으나 전방깊이 및 각막굴절력은 유의한 차이를 보였다. 또한 백내장 수술 후 굴절력 예측의 정확도는 두 측정방법 간 차이가 없었다.
Purpose: To compare the axial lengths, anterior chamber depths, and keratometric measurements and to predict postoperativerefractions of Dual Scheimpflug analyzer Galilei G6® and intra ocular lens (IOL) Master®.
Methods: A total of 50 eyes in 50 patients who received cataract surgery were included in the present study. The axial length, anteriorchamber depth, and keratometry were measured using 2 types of partial coherence interferometries (Galilei G6® and IOLMaster®). The SRK/T formula was used to calculate IOL power and the predictive error which subtracts predictive refraction frompostoperative refraction was compared between the ocular biometry devices.
Results: Axial lengths were 23.36 ± 0.80 mm and 23.36 ± 0.90 mm measured by Galilei G6® and IOL Master®, respectively. Axiallength measured by Galilei G6® was not statistically significant compared with IOL Master® (p = 0.321). The anterior chamberdepth and keratometry were 3.22 ± 0.35 mm and 44.29 ± 1.40 D measured by Galilei G6® and 3.11 ± 0.46 mm and 44.39 ± 1.41D measured by IOL Master®, respectively. The differences of anterior chamber depth and keratometry between the 2 deviceswere statistically significant (p < 0.001 and p = 0.028, respectively). The mean absolute prediction errors were 0.45 ± 0.37 D and0.49 ± 0.39 D in Galilei G6® and IOL Master®, respectively and was not statistically significantly different (p = 0.423).
Conclusions: The ocular biometric measurements and prediction of postoperative refraction using Galilei G6® were as accurateas with IOL Master®.
