We evaluated the prognostic value of laser interference fringe visual acuity (LVA) before surgery for cataract in 130 eyes of 107 diabetic patients. The findings were compared with the maximum visual acuity after phacoemulsification-aspiration or extracapsular cataract extraction with intraocular lens implantation. Actual determination of LVA was possible in 120 eyes. Its value was within one line of the postoperative visual acuity in 58 eyes, 48%, was better by 2 lines or more in 39 eyes, 33%, and was worse by 2 lines or more in 23 eyes, 19%. The LVA value tended to be better than the final visual acuity in posterior capsular cataract and to be worse in diabetic maculopathy. The LVA value was consistently better than the actual visual acuity in another series of 30 eyes of diabetic maculopathy with clear media (p < 0.01). These characteristics of LVA have to be borne in mind before obtaining an informed consent before cataract surgery in diabetic patients.
