For IOL power selection in previously myopic patients, a predictive formula to calculate IOL power based only on the pre-refractive surgery SEQ(m) and current flattest keratometry readings was not statistically different from IOL(exact). The IOL(HisKs), which was also not statistically different from IOL(exact), requires pre-refractive surgery keratometry readings that are often not available to the cataract surgeon.

We report a case of a new syndrome, late asymmetric vault of the AT45 Crystalens intraocular lens (IOL) (Eyeonics Inc.). The late vault, which occurred in 6 month after implantation of the IOL, caused a decrease in uncorrected distance and near acuities and minus-cylinder axis perpendicular to the haptics. Treatment with neodymium:YAG laser capsulotomy and fibrotic band release was successful.
