Predictability of the IOL position using an intra-operative OCT

Accurate IOL power calculation is essential for a good refractive outcome in cataract surgery. Estimation of the post-operative IOL position and therefore the estimated anterior chamber depth (ACD) is nowadays the main source of error in IOL power calculation. Proper measurement of the position and the size of the crystalline lens as well as of the lens capsule after removing the crystalline lens is necessary to improve IOL power calculation. Aim of this study is to evaluate the correlation of these measurements using an intra-operative OCT to the post-operative ACD as well as the refractive outcome.
