Prediction of postoperative visual acuity in cataract patients using the Flying Corpuscle Viewer.
One hundred one cataract patients were tested preoperatively for macular function using the Flying Corpuscle Viewer, a portable blue field entoptic device which utilizes the slit lamp as a light source. Preoperative appreciation of the "Flying Leukocyte Corpuscles" (FLC) indicated a high probability of good postoperative visual acuity, while lack of appreciation of the blue field entoptic phenomenon preoperatively had no predictive value for postoperative visual acuity.
