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 meas-ured 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).
