A phase 2b randomized, double-masked, controlled trial to establish the safety and efficacy of intravitreous administration of Fovista® (Anti-PDGFBB pegylated aptamer) administered in combination with Avastin® compared to Avastin® monotherapy in subjects with subfoveal neovascular age-related macular degeneration.

The objective of this trial is to evaluate the safety and efficacy of the combination of Fovista® intravitreous administration with Avastin® compared to Avastin® monotherapy.

Clinical Investigation of Visual Function After Bilateral Implantation of Two Presbyopia-Correcting Trifocal IOLs.

Primary Objective:To demonstrate noninferiority of ACRYSOF IQ PanOptix presbyopia-correcting IOL Model TFNT00 to the AT LISA tri IOL Model 839MP in mean photopic binocular uncorrected intermediate (60 cm) visual acuity at Visit 4A.Secondary…

Efficacy and cost-effectiveness of toric intraocular lenses in correcting astigmatism in cataract surgery: A Randomised Clinical Trial

The primary objective of this study is to compare the quality of vision following toric IOL implantation and monofocal IOL implantation. The secondary objectives are to compare uncorrected distance vision, spectacle dependence, residual refractive…

Effect of improved intraocular lenses on contrast sensitivity tests

The aim of this study is to measure the results of refractive surgery with aspherical intra-ocular lenses quickly and reliably.

A double blind randomized study on the effectiveness of cyclopentolate 1% and cyclopentolate 1% with tropicamide 1% in dark irided hypermetropic children

To compare the effectiveness of 1) double dose of cyclopentolate and 2) one dose of cyclopentolate and one dose of tropicamide with 3 days, total 5 doses atropine.To investigate whether one dose of tropicamide combined with cyclopentolate is as…

A randomized controlled trial on the visual function after bilateral implantation of two novel Extended Depth-of-Focus intraocular lenses.

The primary objective of this study is to compare the binocular uncorrected intermediate visual acuity (UIVA) at 66 cm under photopic conditions 3 months postoperatively, in a series of patients bilaterally implanted with the Acunex® Vario IOL…

Implantation of a non-diffractive extended depth-of-focus IOL and a monofocal IOL after myopic corneal laser refractive surgery: a randomized controlled trial.

The primary objective of this study is to compare the mean binocular DCIVA at 66 cm under photopic conditions 3 months after cataract surgery, in a series of patients, who previously underwent myopic laser surgery, bilaterally implanted with the non…
