Purpose

The study aimed to compare the Dysfunction Lens Index (DLI) before and after Nd:YAG capsulotomy in monofocal pseudophakic eyes with posterior capsule opacification (PCO).

Setting

Clínica Oftalmológica Dr. Horácio Correia

Methods

Thirty eyes of 25 patients with posterior capsular opacification after uneventful cataract surgery were included retrospectively.

The DLI (0 to 10 points) was calculated by the i-Trace (Tracey Technologies, Houston, Texas, USA) before and after the Nd:YAG laser posterior capsulotomy.

Results

Corrected-distance visual acuity (CDVA) and DLI significantly improved after Nd:YAG laser posterior capsulotomy (P < .01). Spherical equivalent variable did not present a significant change after the procedure (P = 0.65). Before and after the posterior capsulotomy, CDVA presented a significant correlation with the DLI parameter (r = -0.675, P < .01; rho = -0.689, P < .01, respectively).

Conclusions

There was a statistical improvement in the CDVA and DLI after the laser posterior capsulotomy. The DLI presented a strong correlation with CDVA before and after the procedure. The wavefront-derived parameter may optimize the indication for Nd:YAG laser posterior capsulotomy in pseudophakic eyes with PCO.
