PURPOSE To present a novel technique for the implantation of phakic iris-claw intraocular lenses (IOL) in highly myopic cases. METHODS Twelve cases, under the age of 40, with high myopia were included in this retrospective study. The mean follow-up span was 14.4+/-5.8 months. Phakic iris-claw IOL implantation was performed, through a 5.5 or 6.5 mm self sealing scleral tunnel with Bursa techni...

Dear Sir: I would like to congratulate Drs Pareja-Esteban J et al for their article titled “Brown-McLean syndrome and refractive phakic anterior chamber intraocular lenses” (1). The purpose of this letter is to clarify the concept of the Brown-McLean syndrome or circumferential peripheral corneal edema which appears as idiopathic due to a number of cases with anterior chamber refractive intra-o...

PURPOSE To prospectively compare the scotopic pupil size between emmetropes and myopes using a Colvard pupillometer. METHODS The pupil diameters of 55 normal subjects and 55 healthy myopic subjects were measured with the Colvard pupillometer in a low-light situation that simulated the level of light encountered while driving at night. RESULTS The mean (+/- SD) age of the emmetropic subjects...

PURPOSE To evaluate the efficacy, safety, and predictability of sequential implantation of Keraring intrastromal corneal ring segments (ICRS) and an Implantable Collamer Lens phakic intraocular lens (pIOL) with corneal relaxing incisions for refractive correction of keratoconus. SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. DESIGN Cohort study. METHODS This study compr...

The uveal melanoma (UM) is the most common human intraocular tumour. Simian Virus 40 (SV-40) is a small DNA tumor virus detected in some malignancies, including the cutaneous melanoma. In this study an indirect ELISA using synthetic peptides that mimic SV-40 antigens, was employed to detect antibodies against SV-40 in serum samples from UM patients. Our report indicates a significant higher pre...

PURPOSE To evaluate a digital high-speed camera combined with digital morphometry software for dynamic measurements of phakic intraocular lens movements to observe kinetic influences, particularly in fast direction changes and at lateral end points. MATERIALS AND METHODS A high-speed camera taking 300 frames per second observed movements of eight iris-claw intraocular lenses and two angle-sup...

PURPOSE To compare the measurement of anterior chamber depth exclusive of corneal thickness using Orbscan IIz and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method. METHODS Three consecutive measurements of anterior chamber depth were prospectively performed using Orbscan IIz and Paradigm 50-MHz UBM in 40 eyes in 20 individuals. Mean values were compared using the p...

PURPOSE To compare the intraocular pressure- (IOP-) lowering efficacy of fixed combinations travoprost 0.004%/timolol 0.5% and dorzolamide 2%/timolol 0.5% in patients with ocular hypertension or open-angle glaucoma. METHODS In this prospective, multicenter, double-masked, randomized clinical trial, 319 qualifying patients received either travoprost/timolol once daily in the morning (n = 157) ...

PURPOSE To compare the effectiveness of toric foldable iris-fixated phakic intraocular lens (pIOL) implantation and non-toric foldable iris-fixated pIOL implantation with limbal relaxing incisions (LRIs) for correcting moderate-to-high astigmatism in myopic eyes. MATERIALS AND METHODS The medical records of 146 patients (195 eyes) with myopic astigmatism who underwent toric foldable iris-fixa...

PURPOSE To compare the visual outcomes and complications of three different types of phakic intraocular lenses (PIOLs), for correction of moderate to high myopia. METHODS We reviewed 112 myopic eyes undergoing PIOL implantation using Artisan (40 eyes), Artiflex (36 eyes), and implantable collamer lens (ICL, 36 eyes). Best corrected visual acuity (BCVA), intraocular pressure (IOP), pachymetry,...
