PURPOSE To assess the predictability, stability, safety, and efficacy of a collagen copolymer toric phakic intraocular lens (pIOL) to correct moderate and high astigmatism. SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. DESIGN Case series. METHODS After implantation of the TV4b toric Implantable Collamer Lens pIOL, the uncorrected (UDVA) and corrected (CDVA) distance vi...

PURPOSE To evaluate the technique, efficacy, and safety of posterior iris fixation of iris-claw intraocular lens (IOLs) implantation through a scleral tunnel incision for aphakia correction. DESIGN Noncomparative, interventional case series. METHODS A secondary posterior iris fixation of the Artisan iris-claw IOL (Ophthec BV, Groningen, The Netherlands) was implanted for aphakia correction ...

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...

We report the correction of aphakia using an iris-claw, aphakic intraocular lens (IOL) fixated in a retropupillary location in a 17-year-old young man who suffered blunt trauma to his eye 5 months after penetrating keratoplasty (PKP). There were no intraoperative complications. At 21 months after implantation, the patient's uncorrected distance visual acuity was 20/28; his corrected distance vi...

arlo Lovisolo passed away on July 10th this summer after a prolonged battle with a glioblastoma. Born in Acqui Terme in October 1961, he was an outstanding physician and surgeon who enlightened his colleagues in ophthalmology with his surgical talent and meticulous observations, particularly in refractive surgery and most specifically in the field of phakic intraocular lens implantation. Carlo ...

INTRODUCTION Refractive ophthalmic surgery allows refractive errors to be corrected permanently in a safe, effective, and reliable way with few complications. METHODS Selective literature review with special reference to the guidelines of the German Commission for Refractive Surgery. RESULTS With a total of almost 18 million treatments performed to date, laser in-situ keratomileusis (LASIK)...

We present the first case of partial aniridia, traumatic cataract, and peripapillary subretinal hemorrhage after blunt trauma to an eye containing a foldable iris-fixated phakic intraocular lens (pIOL). Although the patient experienced visual loss because of considerable corneal astigmatism and a traumatic cataract, vision was recovered by a 2-stage primary corneal repair and cataract surgery w...
