About

To evaluate the refractive outcomes of cataract surgery in PEX syndrome and determine which of the commonly used IOL formulas (SRK/T, Barrett Universal II and Hill-RBF) is the best in predicting postoperative refractive outcomes in PEX.

Full description

The primary outcome measure was to compare refractive outcomes (MAE, MedAE, percentage of eyes within certain range of prediction error) in PEX and control eyes. The secondary outcome measure was to determine whether any of IOL power prediction formulas (SRK/T, Barrett Universal II and Hill-RBF) is more precise for these challenging eyes.
