PURPOSE To compare visual acuity outcomes and ocular and intraocular optical quality in patients with a monofocal intraocular lens (IOL) or a multifocal IOL with rotational asymmetry. SETTING Vissum Corporation, Alicante, Spain. DESIGN Comparative case series. METHODS Consecutive eyes of cataract patients were divided into 2 groups. One group received(More)
PURPOSE To evaluate the corneal volume, pachymetry, and correlation of anterior and posterior corneal shape in subclinical and clinical keratoconus. SETTING Vissum Corporation, Alicante, Spain. METHODS Eyes were placed into 1 of 4 groups as follows: keratoconus 2 (grade II), keratoconus 1 (grade I), subclinical (subclinical keratoconus), and control(More)
AIM To evaluate the use of preoperative optical coherence tomography (OCT) findings as predictive factors for macular hole (MH) surgery outcomes. METHODS 46 eyes from 46 patients with a diagnosis of MH were included in this study. In all cases, a pars plana 25-gauge vitrectomy with peeling of the internal limiting membrane was performed. Before and after(More)
PURPOSE To evaluate the reading performance, changes in quality of life, and optical performance after cataract surgery with multifocal diffractive intraocular lens (IOL) implantation. SETTING Vissum Corporation, Alicante, Spain. DESIGN Prospective case series. METHODS Patients with bilateral cataract had implantation of Acri.LISA 366D multifocal(More)
The agricultural biotechnology industry applies polymerase chain reaction (PCR) technology at numerous points in product development. Commodity and food companies as well as third-party diagnostic testing companies also rely on PCR technology for a number of purposes. The primary use of the technology is to verify the presence or absence of genetically(More)
PURPOSE To compare bilateral reading performance within the first 6 months after implantation of 4 intraocular lens (IOL) models. SETTING Vissum-Instituto de Oftalmológico de Alicante, Alicante, Spain, and University Eye Clinic, Paracelsus Medical University, Salzburg, Austria. DESIGN Comparative case series. METHODS Patients had bilateral(More)
PURPOSE To determine the interchangeability of 2 anterior segment imaging systems: a very-high-frequency (VHF) ultrasound scanning system (Artemis 2, Ultralink LLC) and an optical coherence tomography (OCT) system (Visante, Zeiss). SETTING Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. METHODS This study comprised 20 eyes without pathology(More)
PURPOSE To evaluate the intraobserver repeatability of pachymetric measurements obtained with a new Scheimpflug photography-based system and the agreement of the measurements with those obtained by optical coherence tomography (OCT). SETTING Vissum Corporation, Alicante, Spain. DESIGN Evaluation of diagnostic technology. METHODS Corneal thickness was(More)
PURPOSE To compare the visual acuity outcomes and ocular optical performance of eyes implanted with a multifocal refractive intraocular lens (IOL) with an inferior segmental near add or a diffractive multifocal IOL. DESIGN Prospective, comparative, nonrandomized, consecutive case series. PARTICIPANTS Eighty-three consecutive eyes of 45 patients (age(More)
PURPOSE To evaluate the clinical outcomes after implantation of the MyoRing (DIOPTEX GmBH, Linz, Austria) by means of femtosecond laser technology in eyes with corneal ectasia. DESIGN Retrospective, consecutive, nonrandomized, case series. PARTICIPANTS A total of 12 eyes of 11 patients with ages ranging from 17 to 50 years were included. All cases were(More)
