PURPOSE To evaluate best corrected visual acuity (BCVA) and photopic and mesopic contrast sensitivity in pseudophakic patients implanted either with the aspheric intraocular lens (IOL) designed to correct for corneal spherical aberration or with a conventional IOL. SETTING Three surgical centers participated this prospective randomized masked comparative(More)
Weekly subconjunctival injections of 4mg repository betamethasone, repeated over three weeks, produced a sustained increase of intraocular pressure (IOP) in 96 % of the treated rabbits. Treatment was generally well tolerated and important systemic toxic effects were present only in a few animals. The ocular hypertension so obtained was constant, well(More)
PURPOSE We compared corneal and total higher order wavefront aberrations in 25 pseudophakic eyes implanted with five different types of intraocular lenses to obtain an objective evaluation of the optical quality of these pseudophakic eyes. Five IOLs per type were studied. METHODS Implanted lenses were the Pharmacia Tecnis Z9000 with negative spherical(More)
PURPOSE To investigate the safety and effectiveness of the AcrySof phakic angle-supported intraocular lens (IOL) (Alcon Laboratories, Inc., Fort Worth, TX) for correction of moderate-to-high myopia in adults. DESIGN One-year interim analysis of a phase 3, nonrandomized, open-label, prospective, multicenter European clinical study. PARTICIPANTS A total(More)
A modified reverse dissection of scleral flaps for glaucoma surgery is described. A conventional square or rectangular flap is designed with deep scleral incisions, the two radial incisions crossing the limbus. A horizontal tunnel is created parallel to the limbus within the peripheral cornea, joining the two radial incisions. This tunnel is then enlarged(More)
BACKGROUND AND OBJECTIVE Patients affected by glaucoma refractory to medical or surgical treatment are difficult to treat. The aim of this study was to evaluate the long-term effect of contact transscleral diode laser cyclophotocoagulation (DLPC) on intraocular pressure (IOP) and on visual acuity of these patients. PATIENTS AND METHODS One hundred and(More)
This study aims to examine evolving indications and changing trends for corneal transplantation in Italy. Corneal transplantations performed with donor tissues distributed by the Veneto Eye Bank Foundation between 2002 and 2008 were prospectively evaluated. Of the 13,173 keratoplasties performed on 11,337 patients, 10,742 (81.5%) were penetrating (PK), 1644(More)
PURPOSE To evaluate the intraocular penetration of lidocaine 4% topically applied before phacoemulsification. SETTINGS Institute of Ophthalmology, University of Verona, and Department of Medical Pharmacology, University of Padua, Italy. METHODS Thirty eyes having phacoemulsification for senile cataract were anesthetized by topical application of(More)
PURPOSE To evaluate clinical outcomes and optical performance of the AT Lisa 909M diffractive multifocal toric intraocular lens (IOL). SETTING Multicenter study. DESIGN Cohort study. METHODS The measured outcomes included refractive error; distance, near (40 cm), and intermediate (60 cm and 80 cm) visual acuities; defocus curve; rotational stability;(More)
