  33-40

Abstract

 Purpose: To evaluate the power of two methods of POTENTIAL ACUITY PINHOLE (PAP) and ILLUMINATED NEAR CARD (INC) in prediction of final visual acuity after cataract surgery.Materials and Methods: This sequential double blind cross-over clinical trial was performed on 100 eyes of 100 patients. The patients were classified into 3 groups in terms of BEST CORRECTED VISUAL ACUITY (BCVA): I-BCVA ≥ 20/50, II-BCVA of 20/60-20/200, and III-BCVA of less than 20/200 to a minimum of 20/400. POTENTIAL VISUAL ACUITY with the two methods (PAP and INC) was predicted before surgery. Eight weeks after cataract surgery, far BCVA was evaluated and the two methods were compared.Results: Mean age of the patients was 65 years (range 30-90). Prediction power of PAP test in groups I, II, and III was 75%, 91.7%, and 73.6%, respectively. Prediction power of INC test in groups I, II, and III was 75%, 87.5%, and 80.6%, respectively. Linear relationship between PAP and post operative far BCVA (R) was 0.71 and far INC was 0.51 (regression analysis, P<0.0001). Linear relationship of PAP method and post operative far BCVA in INC method were: Far Log n = -0.12+0.52 PAP Log n and Far Log n = -0.267+0.44 INC Log n, respectively.Conclusion: Prediction powers for visual acuity in PAP test and INC test were nearly equal. Not considering the preoperative BCVA, both methods had the required power for prediction of visual acuity.
