Purpose To study the effect of neodymium-doped yttrium aluminum garnet (Nd : YAG) laser posterior capsulotomy on refraction and best-corrected visual acuity in pseudophakic eyes. Patients and methods This retrospective nonrandomized analytic study included 110 eyes (n=100 patients) with posterior capsular opacification following a phacoemulsification with foldable hydrophobic intraocular lens implantation surgery. Thorough ophthalmological examinations were performed for all subjects before and after YAG capsulotomy. The best-corrected visual acuity, refractive sphere, and refractive cylinder calculations before and one month after the capsulotomy were recorded. Results Patients’ mean±SD age at the time of surgery was 61.35±14.46 years. The mean±SD refractive sphere changed toward a myopic shift from 0.04±1.78 before capsulotomy to −0.40±1.43 after capsulotomy. The mean±SD refractive cylinder was −1.67±1.45 before capsulotomy and changed to −1.42±1.16 after capsulotomy, making a mild hyperopic shift. Changes in the axis of the cylinder were not statistically significant. A significant improvement was seen in the best-corrected visual acuity from 0.49±0.33 before capsulotomy to 0.23±0.22 after capsulotomy (P<0.001). Conclusion Visual acuity (best-corrected visual acuity) was significantly enhanced following the Nd : YAG laser capsulotomy, and therefore, it is suggested that Nd : YAG laser capsulotomy is a safe and effective alternative treatment for posterior capsular opacification. There are significant changes in the refractive sphere toward a myopic shift following the YAG laser capsulotomy and a significant change in the refractive cylinder toward a hyperopic shift, whereas there were no significant changes in the cylinder axis.

Purpose The aim of this study was to determine the effectiveness of a novel innovative monofocal intraocular lens (Tecnis Eyhance ICB00) compared with the standard monofocal lens (Tecnis-1-piece ZCB00) in terms of contrast sensitivity, postoperative refraction, intermediate visual acuity (VA), and uncorrected and best-corrected distance VA. Patients and methods This prospective comparative interventional clinical study was conducted from January 2021 to November 2021. It included 40 eyes of 20 patients who were divided into two groups, with 10 patients each. Candidates for bilateral cataract extraction by phacoemulsification were included in this study and underwent thorough preoperative examination and postoperative evaluation at 3 months after the second eye operation. The outcome measures included intermediate and distance VA, near add, contrast sensitivity, and incidence of photic phenomena, which was evaluated using a printed questionnaire. The binocular defocus curves were analyzed. Results The study included 20 patients (seven males and 13 females). Binocular and monocular uncorrected and corrected distance VAs were statistically similar in both groups. The Eyhance group demonstrated significantly higher binocular uncorrected and corrected intermediate VA compared with the TECNIS 1-piece group (P<0.001). Defocus and contrast sensitivity values were not significantly different between the two groups. Conclusion Patients who were bilaterally implanted with the new monofocal intraocular lenses achieved significantly higher intermediate VA outcomes without affection of distance VA, with similar mean contrast sensitivity values and low incidence of photic phenomena like halo and glare compared with the standard monofocal lens.
