Collagen copolymer posterior chamber phakic intraocular lens supported by the ciliary sulcus to treat myopia: One-year follow-up
Purpose To evaluate the predictability, stability, safety, and efficacy of Visian V4b Implantable Collamer Lens phakic intraocular lens (pIOL) implantation to treat varying degrees of myopia. Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Design Prospective nonrandomized clinical study. Methods The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, pIOL vault, and adverse effects were evaluated 12 months postoperatively. Results The study enrolled 121 eyes (68 patients). The mean spherical equivalent decreased from −8.61 diopters (D) ± 3.41 (SD) (range −18.75 to −2.25 D) preoperatively to −0.18 ± 0.29 D (range −1.25 to 0.50 D) 12 months postoper…

<p>Visual And Refractive Outcomes In Hyperopic Pseudophakic Patients Implanted With A Trifocal Intraocular Lens</p>
Purpose To assess visual and refractive results after bilateral implantation of a trifocal intraocular lens (IOL) in patients with hyperopia. Methods In a retrospective nonrandomized study, 196 eyes of 98 patients had bilateral implantation of a trifocal IOL. The Barrett Universal II formula was used for IOL power calculation. Eyes were divided into two groups for their analysis: low-moderate, with IOL power ranging from 22 to 26 D, and high, with IOL power ranging from 25 to 34 D. Refractive error was used to assess predictability, and corrected distance visual acuity (CDVA) and uncorrected distance visual acuity values were used to assess efficacy and safety of the surgery. Results Six mo…
