| Aimof the study The aim of this study is to evaluate the changes of wavefront aberrations after performing neodymium : yttrium aluminum garnet (Nd : YAG) laser posterior capsulotomy for the management of posterior capsular opacifications. Patients and methods This study is a prospective study that was performed on 100 eyes of 87 patients with posterior capsule opacification following phacoemulsification, in the period from March 2017 to October 2017. A complete ophthalmic examination and optical wavefront imaging were performed to every patient. Patients underwent posterior capsulotomy using Nd : YAG laser with a follow-up period of 6 months. Results There were no significant changes in postoperative refraction at value more than 0.05 still the best-corrected visual acuity showed a clinically significant at value less than 0.05. The intraocular pressure was statistically significantly increased on the first postoperative day (<0.05) but not in other postoperative visits. Regarding higher order aberrations there was a statistically significant improvement in total third-order aberrations (<0.05), coma aberration (<0.05), total fourth-order aberrations (<0.05), spherical aberration (<0.05), and total higher order aberrations (<0.05) while quadrafoil and fifth-order aberrations showed no statistically significant changes. Conclusion Nd : YAG laser posterior capsulotomy causes a significantly decrease in wavefront aberrations in patients with posterior capsule opacification. | ||||
