“…The VF-14 is a measure of perceived visual function based on 14 everyday activities that may be affected by cataracts. No questionnaire speci cally assessing visual disabilities for PCO has been published, but the VF-14 has been validated in patients with other ocular diseases [25,26]. Each participant completed the questionnaire under the guidance of the same ophthalmologist.…”

Background: A prospective cohort study was performed to evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. Methods: One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤ 0.1 group and logMAR CDVA > 0.1 group. CDVA， and the Visual Function 14 index (VF-14) score were estimated before and one month after capsulotomy. The objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. Results：In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤ 0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = -0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = -0.669). In the logMAR CDVA ≤ 0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). In logMAR CDVA > 0.1 group, the area under the curve of the ROC of the OSI was 0.996 (P = 0.000). In logMAR CDVA ≤ 0.1 group, the area under the curve of the ROC of the OSI was 0.943 (P = 0.000).Conclusions：The OSI was useful for evaluating of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and completely objective examination. Trial registration: The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).
