Next-generation device shows promise in aphakic refractive measurements
January 1st 2010Preliminary results from a study investigating use of a intraoperative wavefront aberrometer indicate that it accurately measures the refraction in aphakic eyes and translates the data into IOL power to enable excellent outcomes after cataract surgery.
Techniques, devices improve refractive results after cataracts
January 1st 2010Accurate biometry, accurate keratometry, use of both an appropriate IOL power calculation formula and personalized A-constant, and the elimination of astigmatism all are essential factors for obtaining a good refractive result following cataract surgery in eyes with a history of keratorefractive surgery.
