• To evaluate the safety of up to 3 additional courses of oral QLT091001 administered once daily for 7 days in subjects with LCA or RP caused by RPE65 or LRAT gene mutations who have been treated previously with a single 7-day course of QLT091001 in…
The objective of this investigation is to describe visual outcomes and assess the safety at 12 months (330 - 420 days) post bilateral implantation of the AcrySof® IQ PanOptix* Presbyopia correcting IOL Model TFNT00.
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…
The primary statistical objective of this study is to describe mean differences in corneal staining (type and area), for OPTI-FREE EverMoist Multi-Purpose Disinfecting Solution compared to baseline.
The objectives of this study are to assess and compare bilateral uncorrected distance visual acuity and distance spectacle independence post bilateral implantation of AcrySof Toric IOLs and monofocal IOLs.
This study has two major goals. The first goal of this study is to evaluate whether the disabilitating effects of crowding can be reduced by the use of a magnifier early in life. The second goal is to investigate motor and visual development of…
The main objective of this study is to evaluate the ability of the PRECIZION Presbyopia IOL to provide near, intermediate and distance vision in patients undergoing cataract extraction and intraocular lens implantation. Study outcomes will be used…
What is the effect of image magnification on straylight values and is there a correlation between change in straylight values and change in visual acuity after pIOL (Artisan/Artiflex) implantation.
To prevent avoidable visual impairment, in our controlled study, we want to contribute to the evidence of good treatment effects on visual functions (visual acuity both distances near and at distance, accuracy of accommodation), prevention of…
The goal is to study the effectiveness of visual stimulation in children up till the age of 8 with ocular or cerebral visual impairment with or without intellectual disabilities.Since the commission explicitly stated that the intervention should…
To evaluate long term results of DSEK and to compare pre- and postoperative quality of vision in patients with Fuchs' endothelial dystrophy.
To determine straylight values in pseudophakic patients. This study will lead to objective documentation of loss of visual function among pseudophakic patients and will lead to more insight in the etiology of straylight among this group of patients…
Primary objectives:A. To determine the ability of the Toric ARTIFLEX PIOL to reduce astigmatism (performance); B. To establish the mechanical properties of the lens in the anterior chamber in terms of rotational stability of the lens, tilting of the…
The primary purpose of this study is to assess the efficacy of occlusion therapy (visual acuity of the amblyopic eye five weeks after cessation of occlusion therapy) in previously untreated patient with amblyopia between seven and forty years of age…
• To evaluate whether 7-day treatment with oral QLT091001 can improve visual function in subjects with LCA or RP caused by RPE65 or LRAT gene mutations.• To evaluate duration of visual function improvement (if observed) in subjects with LCA or RP…
Primary Objective: To determine when straylight stabilizes in eyes after cataract surgery, determine the amount of straylight in eyes implanted with a Clareon monofocal IOL and a Vivinex XY1 monofocal IOL, and compare these straylight values to…
To evaluate the efficacy and safety of brolucizumab used in a Treat-to-Control (TtC) regimen for the treatment of patients with neovascular age-related macular degeneration (nAMD) with the objective to evaluate the potential to reduce treatment…
The objectives of the study are to assess the safety and tolerability of ascending doses of SAR422459 in patients with Stargardt macular disease and to evaluate the possible biological activity of SAR422459.
To achieve a valid comparison of the effect of gaming and patching therapy on visual acuity, with compliance measured electronically.
The aim of this study is to validate a recently created online refraction method by comparing the outcomes of the online refraction method with the *golden standard* manifest refraction.
