Assessment of Posterior Capsular Opacification of Korean Using Straylight and Glare Sensitivity Meter

ABSTRACT

PURPOSE: To evaluate posterior capsular opacity (PCO) using straylight and glare sensitivity meter and to compare availability of straylight and glare sensitivity with known methods for PCO evaluation. METHODS: Thirty-six pseudophakic eyes with PCO were selected for this study. Best-corrected visual acuity (BCVA), straylight (C-quant, Oculus GmbH, Wetzlar, Germany) and glare sensitivity (Binoptometer, Oculus GmbH, Wetzlar, Germany) were measured before mydriasis. After mydriasis, PCO images were captured with a slit-lamp and analyzed using the Evaluation of Posterior Capsular Opacification (EPCO) program (EPCO software, University of Heidelberg, Heidelberg, Germany). The same measurements were taken after capsulotomy and compared with pre-capsulotomy data. RESULTS: After capsulotomy, BCVA, EPCO score and straylight were improved with statistical significance (p < 0.05). Cases of PCO with mildly decreased visual acuity showed statistically significantly improved EPCO score and straylight (p < 0.05). Glare sensitivity did not show significant improvement but was statistically significantly correlated with straylight (p = 0.023, Rho = 0.732). CONCLUSIONS: Straylight is an available measurement for evaluation of PCO. Glare sensitivity meter which correlates with straylight can be used as a supportive measurement.
