![]() Advances in cataract surgery and intraocular lenses have improved surgical outcomes, promoted early visual rehabilitation, and reduced complications. The timing of surgery depends on weighing the benefits of surgery against the risks. Although age-related cataracts progress slowly, cataract surgery is ultimately required. The OSI appears to be the most effective parameter for this purpose.Ĭataracts are a common cause of vision impairment in the older population, affecting the quality of vision and visual acuity and negatively impacting daily activities. The MTF, OSI, Strehl ratio, PVA 100%, PVA 20% and PVA 10% may be useful parameters for preoperative decision-making in cataract surgery. ROC analysis showed that the OSI had the largest area under the curve and that the sensitivity and specificity of the OSI were 83.9 and 84.6%, respectively, at the optimal cut-off point of 2.35. The BCVA, OSI, PVA 100%, PVA 20%, and PVA 10% were higher in the cataract group compared to those in the control group, while the MTF and Strehl ratios were lower ( p < 0.001 for all). The main parameters measured were sensitivity and specificity. ![]() The sensitivity and specificity of the different parameters were analyzed using the receiver operating characteristic (ROC) curve. The objective scatter index (OSI), modulation transfer function (MTF), Strehl ratio, predicted visual acuity (PVA) 100%, PVA 20%, and PVA 10% were measured using the OQAS. The best corrected visual acuity (BCVA) was measured. Sixty-seven eyes from 67 patients undergoing cataract surgery and 109 eyes from 109 control subjects were compared. We investigated the clinical utility of the OQAS for decision-making in cataract surgery. This study shows the role of the optical quality evaluation system for decision-making in cataract surgery. The Optical Quality Analysis System (OQAS, Visiometrics SL, Terrassa, Spain) assesses the optical quality of the eye in cataract patients. A cataract is a common cause of vision impairment that requires surgery in older subjects.
