Study of early refractive changes following Nd: YAG capsulotomy for posterior capsule opacification in pseudophakia

Abstract

Purpose To study the effect of capsulotomy size on refraction and best corrected visual acuity (BCVA). Methods Thirty five patients were examined pre procedure and 3 days after Nd: YAG capsulotomy. Patients were divided into 3 groups based on post procedure capsulotomy size. Changes in cylindrical error, spherical error & BCVA were compared in 3 groups. Results We found a higher hyperopic shift in patients belonging to larger capsulotomy group. In 3 groups the change in cylindrical error was found to be significant in the larger capsulotomy group. The change in BCVA pre & post procedure was also found to be significant among the 3 groups. Conclusion Patients who underwent a larger capsulotomy had a higher hyperopic shift and improvement in vision. The cylindrical correction changed significantly depending on the size of the opening created.
