Causes of Explantation of Phakic Intraocular Lenses We read with interest the article by Alió et al.1 on phakic intraocular lens (PIOL) explantation in the January issue. There is an ongoing debate about the long-term safety of PIOLs, especially angle-supported lenses.2 In late 2014, Alcon Laboratories, Inc. discontinued production of the AcrySof CACHET Phakic Lens (Alcon Laboratories, Inc., Fo...

PURPOSE To demonstrate the methodology described by the American National Standards Institute (ANSI) Standard Subcommittee on Astigmatism Analysis reporting a standardized method of presenting astigmatism data by laser systems that reshape the cornea also applies to toric phakic intraocular lens (IOL) data. METHODS The U.S. Food and Drug Administration trial of the Visian Toric Implantable Co...

PURPOSE To show the clinical use of the NIDEK OPD-Scan wavefront aberrometer and OPD-Station software in anterior segment surgery and pathology. METHODS Case examples are presented along with discussion about the relevant clinical data obtained from the OPD-Scan and OPD-Station software. RESULTS Six case examples including cataract surgery, secondary IOL implantation, phakic intraocular len...

PURPOSE To evaluate the functional and the anatomical outcomes after implantation of phakic posterior chamber intraocular lenses (IOLs) in highly myopic eyes. SETTING Service d'Ophtalmologie, Hôpital Purpan, Toulouse, France. METHODS Fifty-eight eyes of 46 patients that had implantation of phakic posterior chamber lenses for high myopia were evaluated. Predictability, efficiency, safety, an...

A male nematode was extracted from iris fibers of a man from the Brazilian Amazon region. This nematode belonged to the genus Pelecitus but was distinct from the 16 known species in this genus. Similarities with Pelecitus spp. from neotropical birds suggested an avian origin for this species.

A case of human intraocular dirofilariasis is reported from northern Brazil. The nematode was morphologically and phylogenetically related to Dirofilaria immitis but distinct from reference sequences, including those of D. immitis infesting dogs in the same area. A zoonotic Dirofilaria species infesting wild mammals in Brazil and its implications are discussed.

BACKGROUND The aim was to evaluate the safety, efficacy, stability and predictability of posterior chamber collagen copolymer phakic intraocular lens (pIOL) implantation to correct myopia and myopic astigmatism associated with keratoconus. METHODS The unaided vision and visual acuity, refraction and adverse events were measured in 22 keratoconic eyes of 14 patients after using an implantable ...
