Purpose: To determine whether postoperative outcome after a cataract surgery in patients with retinal pathology can be better predicted with SLAP than preoperative refraction Methods: A prospective study of 11 eyes in 11 patients (six males and five females) with retinal pathology and cataracts. Retinal pathology included prior retinal detachment, age–related macular degeneration (ARMD), diabetic retinopathy, prior ruptured globe repair, and ischemic optic neuropathy, with preoperative visual acuities ranging form 20/70–4/400. SLAP and microperimetry were performed with a confocal SLO (SLO, Rodenstock, Danbury, CT, USA) and compared to standard refraction using a Snellen visual acuity chart to determine the benefit of cataract extraction. All patients underwent the preoperative assessment, cataract extraction surgery and postoperative follow up by a single ophthalmologist. Assessment of vision was documented as lines of improvement in visual acuity. Results: The visual improvement predicted by SLAP was more accurate than preoperative refraction in all of the patients in this series. Visual outcomes following cataract extraction surgery correlated well with those predicted by SLAP (p < 0.05). Conclusions: SLAP is superior to standard refraction in assessment of potential visual outcome in patients with retinal pathology and cataracts
