Considerations of Visual Quality in Ocular Surgery as Presented at Dry Eye University

Main Article Content

Frank Bowden


Visual quality may be described as the visual experience which reflects the optimal optical efficiency of the eye. Patients undergoing ocular surgery expect improvement in visual acuity. Ocular surgeons typically aim to improve best-corrected visual acuity. Refractive surgeons, on the other hand, strive to improve uncorrected visual acuity. It is not uncommon that patients with excellent corrected visual acuity following surgery may be dissatisfied with visual quality which is less than anticipated due to unexpected visual disturbances. These visual phenomena may include ghosting, glare, halos, reduced contrast sensitivity, and visual fluctuation.
