Refractive changes after yag laser capsulotomy in pseudophakic patients

الملخص EN

Background: The aim of our study was to evaluate the effect of Nd:YAG laser posterior capsulotomy on patient’s refractive status .

Methods: a retrospective study that involved 30 eyes (of 30 patient) treated with Nd:YAG laser capsulotomy due to posterior capsular opacification after uncomplicated phacoemulsification surgery and intraocular lens implantation.

Complete ocular examinations were done for all patients before and after YAG capsulotomy.

The best corrected visual acuity , sphere and cylinder were obtained before capsulotomy ,one week and one month after capsulotomy and changes were investigated.

Data was analyzed statistically.

Results: It was found that the mean refractive sphere shift towards myopic changing , The mean refractive cylinder changes towards hyperopic shift , there were no statistical significance of any change in axis of the cylinder .

Conclusion: Statistical significant improvement in BCVA after Nd:YAG laser capsulotomy, so Nd:YAG is an effective instrument used in non-invasive treatment of posterior capsular opacification
