PURPOSE To review the peer-reviewed literature reporting postoperative complications of the most recent models of Visian Implantable Collamer posterior chamber intraocular lenses (ICL, STAAR Surgical Co). METHODS A literature search of the PubMed database was performed to identify all articles related to ICL complications. Articles were obtained and(More)
PURPOSE To evaluate the changes in corneal transparency and thickness measured objectively using Pentacam Scheimpflug (Oculus Optikgeräte GmbH) corneal tomography (densitometry) after corneal cross-linking (CXL). METHODS Twenty-two eyes from 15 patients with keratoconus underwent CXL. Corneal thickness and curvature as well as lens and corneal(More)
PURPOSE The purpose of the present study was to measure equilibrium water content (EWC) and refractive index of conventional and silicone hydrogel soft contact lenses (SCL) using a hand refractometer and an automated refractometer. METHODS Sixteen SCL were used in this study including 12 conventional SCL not containing siloxane moieties (equilibrium water(More)
PURPOSE To evaluate the effect of wear on dynamic in vitro dehydration of silicone hydrogel (Si-Hi) contact lens (CL) using a previously described gravimetric procedure. METHODS Five different silicone hydrogel (Si-Hi) contact lenses (CL) were evaluated after being worn by patients under daily wear conditions for 15 days to 1 month. Lenses were(More)
PURPOSE To evaluate the long-term safety and efficacy of posterior chamber collagen copolymer phakic intraocular lens (pIOL) implantation to correct myopia. SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. DESIGN Cohort study. METHODS Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, pIOL vault, endothelial(More)
PURPOSE To determine objectively the changes in the optical quality of the air-tear film interface by measuring the modulation transfer function (MTF) of the anterior surface of the film. METHODS Air-tear film interface MTF was determined from the wavefront aberration obtained from corneal elevation maps and custom software. MTF and Strehl ratio were(More)
PURPOSE To compare the intraocular pressure (IOP) values during a 3-month period after implantation of the new Visian Implantable Collamer Lens (ICL; STAAR Surgical Company, Nidau, Switzerland) V4c design with CentraFLOW technology without iridotomy using a standard procedure followed by implantation of the conventional ICL V4b model. DESIGN Retrospective(More)
PURPOSE To evaluate the performance of two experimental contact lenses (CL) designed to induce relative peripheral myopic defocus in myopic eyes. METHODS Ten right eyes of 10 subjects were fitted with three different CL: a soft experimental lens (ExpSCL), a rigid gas permeable experimental lens (ExpRGP) and a standard RGP lens made of the same material(More)
PURPOSE To compare thickness measurements of the central 6.0 mm of the cornea obtained with the Orbscan(R) II topography system and topographical ultrasound pachymetry. SETTING School of Optometry, University of Santiago de Compostela, Galicia, Spain. METHODS In 24 right eyes, pachymetric measurements were taken at the center and 1.2 mm and 3.0 mm on(More)
PURPOSE To investigate the biomechanical properties of the normal cornea, and correlate them with central and peripheral corneal thickness and age. METHODS Seventy-six right eyes of volunteers were measured with Ocular Response Analyzer (ORA), ICare rebound tonometry and an ultrasound pachymeter at corneal center and at 4 mm from corneal center in the(More)
