Abstract

Abstract: : Purpose: To investigate and compare the accuracy of the scanning laser ophthalmoscope (SLO) with the potential acuity meter (PAM) in predicting the visual outcome after cataract surgery. Method: This prospective and double blind study included 35 patients with cataract, eight of whom had retinal disease. Results: SLO predicted within 2 lines of visual outcome in 21 of 35 (60%) patients while PAM was correct in 19 of 35 (55%). In patients with dense cataract and vision worse than 20/100, SLO predicted within 2 lines in 6 of 17 patients (35.3%) with cataract and in 2 of 3 with retinal disease and cataract. In contrast, PAM was correct only in 2 of 17 (11.8%) with cataract and in 0 of 3 with retinal disorder. Conclusion: PAM and SLO are comparable in predicting visual outcome after cataract surgery in the patients with mild and moderate cataracts, making PAM more practical due to its low cost. SLO may be a valuable alternative for the patients with dense cataract / retinal disease.
