Abstract

To assess the effect of posterior capsular opacification (PCO) and Neodymium-doped:Yttrium Aluminium Garnet (Nd:YAG) laser capsulotomy on tilt and decentration of intraocular lens (IOL) at vertical and horizontal meridians. The study included 64 eyes of 64 patients. IOL decentration and tilt were measured using a Scheimpflug camera before and 1 month after Nd:YAG capsulotomy. Corrected distance visual acuity (CDVA) and manifest refraction were also determined. Between-group differences of IOL position change and the effect of Nd:YAG laser capsulotomy were analyzed. In the PCO group, before capsulotomy, CDVA was significantly lower than that after capsulotomy and of the control group values (p = 0.001 for both). No significant difference was observed in CDVA between the control group and the PCO group after capsulotomy (p = 0.854). Before capsulotomy, the angle of tilt and decentration at both meridians was significantly higher than that in the control group (tilt: p < 0.001; for both decentrations: p = 0.001, p = 0.003, respectively). A significant decrease was observed in the angle of tilt at both meridians (horizontal p = 0.001, vertical p = 0.001) from before to after capsulotomy in the PCO group. Although decentration was i...Continue Reading
