Prediction of the effective postoperative (intraocular lens) anterior chamber depth

The postoperative ACD was significantly correlated with and hence predictable by a 5-variable regression method incorporating the preoperative axial length, ACD, keratometry reading, lens thickness, and refraction as the most significant variables. The statistical relationship can be used to create a new ACD prediction algorithm to incorporate in a modern “thick lens” IOL power calculation formula with significant improvement in the accuracy of the refractive predictions as a result.
