title: New methods for predicting visual acuity after cataract surgery.
abstract: Recent advances in technology have contributed to better evaluation of potential visual acuity in patients with cataracts. The blue field entoptic test, the clinical interferometers, and the Potential Acuity Meter are discussed with respect to their basic principles, clinical uses, advantages, and limitations. There are problems in evaluating these instruments, but their findings can play an important role in clinical decision making.
