Abstract


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.
