갈릴레이 G6와 IOL 마스터를 이용한 안구생체계측과 백내장 술후 굴절력의 비교연구

초록

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®.
