1/2. Pupillary block glaucoma secondary to posterior chamber phakic intraocular lens implantation for high myopia.We describe a complication of posterior chamber phakic intraocular lens (PCP IOL) implantation for high myopia. Both eyes of a 44-year-old patient were treated prophylactically with a neodymium:YAG laser iridotomy before PCP IOL implantation. Bilateral PCP IOL implantation was performed uneventfully, although a peripheral iridotomy was required immediately after implantation in the right eye because of early pupillary block glaucoma. Two months later, the left eye developed pupillary block glaucoma despite apparently patent iridotomies. The PCP IOLs were subsequently removed.- - - - - - - - - - ranking = 1keywords = myopia (Clic here for more details about this article) |
2/2. Total pupillary capture with a foldable silicone intraocular lens.We report a case of total pupillary capture on the 1st postoperative day in a patient who had undergone phacoemulsification and placement of a silicone foldable posterior chamber intraocular lens. Anterior displacement of the lens optic resulted in 2.25 diopters of induced myopia. Dilation of the pupil corrected the lens capture and reversed the induced myopia, yielding a refraction of plano. Higher rates of pupillary capture have been associated with sulcus fixation and nonangulated flexible (polypropylene) haptics. Contraction of the capsular bag on the flexible polypropylene haptics of this silicone lens is thought to force the optic anteriorly, increasing the probability of lens capture by the iris.- - - - - - - - - - ranking = 0.4keywords = myopia (Clic here for more details about this article) |
