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…
The objective of this trial is to assess the effects and costs of DMEK vs. DSAEK in order to determine whether the new technique is effective and cost-effective over the standard technique.
The primary objective is to show a difference in responder rates between the study product (T4020) and the vehicle : a reduction of 50% or more in keratitis/ulcer area from baseline (inclusion visit = V2 = Day 0) assessed at Day 28 (Visit 6).
To visualize the different components of RAP lesions with high resolution Doppler OCT, and to evaluate the change in intra- and transretinal flow after treatment.
To document mean and range of straylight values in patients with anterior segment disorders possibly under several visual angles
The main objective is to describe the interactions between physical sensory stimulations and high-level prior assumptions that give rise to visual perception. In two secondary objectives, we will advance novel model-based neuroimaging data-analysis…
The main objective is to determine whether the administration of allogeneic serum micro eye drops using the mu-Drop device is non-inferior to the conventional sized drops in terms of effectiveness and safety.
To monitor the effect of the free plate technique in Baerveldt implant surgery on the postoperative eye motility.
Primary: to compare the treatment effect of ranibizumab PRN (visual acuity loss and/or SD-OCT disease activity guided retreatment) versus aflibercept bimonthly regimen on central retinal thickness stability as measured by mean fluctuations between…
The objective of this study is to compare the efficacy and safety of the preservative-free fixed-dose combination of tafluprost 0.0015% and timolol 0.5% eye drops to those of tafluprost 0.0015% and timolol 0.5% eye drops given as individual…
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…
Primary objective:To demonstrate that the mean change from baseline in Best Corrected Visual Acuity (BCVA) over a 12 month treatment period obtained with either a 0.5 mg ranibizumab *Treat and Extend* (TE) dosing regimen with adjunctive laser, and/…
To determine the aberration pattern of the cornea from its shape.
The objective of this study is to develop and test a DSL-protocol which will focus on proper use of hearing-aids, and will also provide patients (and their significant others) with specific skills to improve the use of the senses and communication.…
The primary purpose is the efficacy of occlusion therapy initiated in patients with untreated amblyopia between twelve and forty years of age. The secondary purposes are rate of recurrence, refractive adaptation, and the social-economic and ethic…
To investigate the additional value of partial endothelial trepanation (PET) in a deep anterior lamellar keratoplasty (DALK) procedure in terms of efficacy and safety in patients with keratoconus.
To identify eyes that show worsening and disease progression (progressor phenotypes). Primary ObjectiveTo identify *progressors* in retinal vascular disease and central retinal edema in type 2 diabetic patients with early NPDR, based on retinal…
To evaluate whether straylight assessments [log(s)] can contribute to develop/refine the decision tree for the indications AC-PIOL, RLE or CE.
The purpose of this research study is to demonstrate that the fixed combination brinz/brim used twice daily has a similar effect (both in terms of reduction of the eye pressure and possible side effects) as brinzolamide and brimonidine used twice…
The objectives of this study are to assess and compare at 6 months 1) the percentage of subjects achieving bilateral uncorrected distance visual acuity and bilateral uncorrected near visual acuity <= 0.1 logMar; 2) spectacle independence at…
