“…Furthermore, it has been shown that the incidence of retinal detachment and cystoid macular oedema after Nd:YAG laser capsulotomy is uncommon in eyes that have previously undergone phacoemulsification and in-the-bag implantation of an IOL. [19][20][21][22] These findings suggest that the incidence of the adverse effects may not differ markedly between eyes with a small capsulotomy and those with a large capsulotomy.…”

Purpose The aim of this study was to examine the influence that the size of a neodymium:yttrium-aluminium-garnet (Nd:YAG) laser capsulotomy performed for posterior capsule opacification (PCO) has on visual acuity (VA), and on contrast VA and that in the presence of glare (glare VA). Methods A total of 41 consecutive eyes with PCO first underwent Nd:YAG laser capsulotomy of smaller than pupillary size, after which the capsulotomy was secondarily enlarged, 2 weeks later, to greater than pupillary size. Best-corrected VA, and contrast VA and glare VA under photopic and mesopic conditions were measured after the small and large capsulotomies were made. Results After enlargement, the mean capsulotomy area increased significantly from 4.8 to 15.3 mm 2 (Po0.0001). Best-corrected VA did not improve significantly after enlargement (P ¼ 0.1282). However, photopic contrast VA and glare VA at moderate to low contrast visual target before enlargement were significantly worse than those after enlargement (Pp0.0242); furthermore, mesopic contrast VA and glare VA improved significantly after enlargement (Pp0.0431). Conclusion Contrast VA and glare VA with a small capsulotomy were significantly worse than those with a large capsulotomy, which suggests that a capsulotomy larger than the pupillary size is necessary to restore contrast sensitivity and glare disability.

“…The numbers of laser pulses and energy delivered were not risk factors [10]. Lewis et al [30] studied 136 patients who underwent Nd:YAG laser capsulotomy for secondary opacification of the posterior capsule after extracapsular cataract extraction and they followed the patients for 6 months. Fluorescein angiography was repeated 4 to 8 weeks after the procedure.…”

Purpose. The aim of this study is to examine the influence of capsulotomy size on, spherical equivalent (SE), intraocular pressure (IOP), and macular thickness. Materials and Methods. Sixty-eight patients were examined preoperatively and 1, 4, and 12 weeks after Nd:YAG capsulotomy. Patients were divided into two groups based on the postoperative capsulotomy size. Changes in SE, IOP, and macular thickness were compared between two groups. Results. We found a higher hyperopic shift in large capsulotomy group. In both groups 1 and 2, IOP increased 1 week postoperatively. Intraocular pressure rise in group 2 was higher than in group 1. Both groups had increased macular thickness at 1 week postoperatively. The degree of macular thickening was similar in group 1 and group 2. Comment. Patients who underwent a larger capsulotomy have a higher hyperopic shift and IOP elevation. Rise in macular thickness was similar in large and small capsulotomy groups.

“…After-cataract is associated with decreased visual acuity, and may cause IOL decentration, intraocular inflammation, and secondary glaucoma (Apple et al, 1992). After-cataract is usually treated with laser capsulotomy procedures which can be associated with serious complications such as increased intraocular pressure, retinal detachment and macular edema (Channell and Beckman, 1984 ;Fastenberg, Schwartz and Din, 1984 ;Lewis et al, 1987 ;Ober et al, 1986).…”
