The effect of Nd : YAG laser posterior capsulotomy size on refraction, intraocular pressure, and central macular thickness

Background Regarding the Nd : YAG laser capsulotomy, various complications were reported, such as intraocular lens dislocation, cystoid macular edema, and rise in the intraocular pressure (IOP). The influence of capsulotomy size on the spherical equivalent (S/E), IOP, and the central macular thickness (CMT) after the procedure is controversial. Therefore, carrying out a capsulotomy opening with optimum size and site is slightly challenging. Aim The study aimed to evaluate the influence of the Nd : YAG laser posterior capsulotomy size on S/E, IOP, and CMT. Patients and methods A total of 40 pseudophakic eyes of 40 patients treated with Nd : YAG laser capsulotomy for posterior capsular opacification were evaluated preoperatively and 1, 4, and 12 weeks after the procedure. The patients were divided into two groups based on the postprocedural size of the capsulotomy opening. The two groups were studied based on the changes in the S/E, best-corrected visual acuity, IOP, and CMT after the capsulotomy. Results There was a statistically significant and stable improvement in the best-corrected visual acuity after the procedure in the two groups over the whole period of follow-up (P
