영문 초록

Purpose: To compare the ocular biometry and prediction of postoperative refractive outcomes using IOL Master？？700 (Carl Zeiss Meditec AG, Jena, Germany) and A-scan (Aviso？？, Quantel Medical, Cournon-d Auvergne, France) in severe cataract. Methods: Seventy nine eyes with severe cataract under visual acuity of 1.7 logMAR were scheduled for cataract surgery. Axial length and anterior chamber depth were measured preoperatively with IOL Master？？ 700 and A-scan. Mean absolute error was obtained with the difference between preoperative predictive refraction and postoperative refraction outcome using autorefraction. Results: Forty three cases received phacoemulsification and 36 received extracapsular cataract extraction. The mean absolute error between IOL Master？？700 and A-scan in 20 eyes received phacoemulsification and 11 eyes received extracapsular cataract extraction (ECCE) was not significant (p < 0.001 and p < 0.001, respectively). IOL Master？？700 measured mean axial lengths and anterior chamber depths longer than A-scan in phacoemulsification group (p < 0.001 and p < 0.001, respectively). However, there was no significant difference in mean axial length of ECCE group between two devices (p = 0.350). Conclusions: There was no significant difference between IOL Master？？700 and A-scan in prediction of refractive outcomes after surgery of severe cataract under visual acuity of 1.7 logMAR. If available, IOL Master？？700 can be considered as reliable method for prediction of postoperative refractive outcomes in cases of severe cataract.
