PurposeThis was a prospective descriptive study to determine the changes in intraocular lens (IOL) position after neodymium-doped yttrium–aluminum–garnet (Nd:YAG) laser posterior capsulotomy by measuring anterior chamber depth (ACD) and refraction, including the spherical equivalent (SE) and cylinder.Materials and methodsForty-seven pseudophakic eyes with posterior capsule opacification of 29 patients were included. Nd:YAG laser posterior capsulotomy was performed. Patients’ ACD and refraction were measured before the treatment, as well as after the treatment at 1 week and 3 months. IOLMaster® and an automated refractometer were used at the Department of Ophthalmology, King Chulalongkorn Memorial Hospital, Bangkok, Thailand.ResultsThere were no statistically significant differences in ACD and SE before and after laser treatment at 1 week and 3 months (repeated analysis of variance, P=0.582 and P=0.269, respectively). Both backward IOL movement (number [n]=29) and forward IOL movement (n=18) were found. Some changes in cylindrical refraction were found at 1 week, but decreased at 3 months after capsulotomy (baseline cylinder: −1.16; cylinder at 1 week and 3 months: −1.00 and −1.14, respectively; P=0.012). These changes were the same with one-piece and three-piece IOLs.ConclusionNd:YAG laser posterior capsulotomy did not significantly change ACD and SE. It led to cylinder change at 1 week after laser, but the effect decreased at 3 months. This effect was small and may not be clinically significant.

It was feasible for a trained non-ophthalmologist health care worker to obtain retinal images of infants using the Pictor that were of sufficient quality to identify infants with type 1 ROP. [J Pediatr Ophthalmol Strabismus. 2018;55(4):245-253.].
