Abstract		Changes of retinal light sensitivity after YAG-laser capsulotomy: Purpose. The aim of this prospective study was to investigate the changes of retinal light sensitivity of central visual field in patients with posterior capsule opacification (PCO) after YAG-laser capsulotomy. Patients and methods: Our study includes 18 eyes (18 patients) with PCO after phacoemulsification and intraocular lens implantation. In all patients YAG-laser capsulotomy was performed. In all patients, a threshold visual field analysis was carried out with the 30-2 program of the automated Humprey Field Analyzer before and one month after the procedure. Results: In all patients a significant improvement of visual acuity was observed one month after capsulotomy (p=0,00004). One month after YAG-laser treatment, a significant improvement of retinal light sensitivity in the central visual fields was also observed. The average MD (mean deviation) before the procedure was -6,88 db (+/- 3,9, max. 11.7, min. 2.17) and after the procedure -4.58 db (+/- 4.37, max. -10.87, min. +0.51). The improvement in MD was statistically significant (p=0.00475). No correlation was established between the improvement of retinal light sensitivity and patient age or the size of capsulotomy. Discussion: Our study shows that the improvement of retinal light sensitivity is significant after YAG-laser capsulotomy and does not depend on patient age or capsulotomy size.
