Filter by:Patients who underwent presbyopic correction with bilateral bifocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require near vision acuity (NV), (ie. book reading). However, it is known that light intensity and temperature has a great impact on near vision capacity. Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and temperature) for ADLs that demand near vision acuity for a sample oa patients who underwent presbyopic correction with bilateral bifocal intraocular lenses implantation
Patients who underwent bilateral bifocal or trifocal lenses implantation for presbyopia correction with monofocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require: a) distant vision (DV), (ie. driving), b) intermediate vision (IV), (ie. computer word processing), c) near vision (NV), (ie. book reading). Primary objective of the study is the comparison in a series of ADLs of two cohorts of patients (group 1: subjects with bilateral bifocal lenses implantation, group 2: subjects with bilateral trifocal lenses implantation)
The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D with no more than 0.75 D of refractive cylinder. The Raindrop Near Vision Inlay will be implanted in the non-dominant eye.
Demand in near vision correction in the community exist in the Bangladesh with a thin presence of eye- care. This study aimed to test the skill of BRAC service-providers in identifying presbyopia-cases, to ensure frequent services, meeting the community need. This was non-inferiority equivalence randomized intervention trial, done during February-June 2015, in six randomly selected sub-districts, where 2059 camp-patients were screened. BRAC Health-cadres; program organizers (PO), upgraded shasthya- shebikas (USS) and shasthya- shebikas (SS), were assigned to three different arms consisting two sub-districts through permuted-block randomization.105 eye-camps were organized with minimum 500 sample per arm. Sensitivity and specificity was calculated to understand screening performance. Screening reports were matched with the gold standard by recruiting refractionists.
The purpose of this study is to evaluate CLEAR CARE® PLUS (CCP) compared to non-HYDRAGLYDE® multi-purpose contact lens solutions in presbyopes currently wearing soft contact lenses and experiencing symptoms of dryness.
The purpose of this study is to evaluate OPTI-FREE® PureMoist® (OFPM) compared to non-HYDRAGLYDE® multi-purpose contact lens solutions in presbyopes currently wearing soft contact lenses and experiencing symptoms of dryness.
A study to Establish Safety, Tolerability, and Efficacy of PresbiDrops (CSF-1) in Presbyopic Subjects.
This is an interventional, non-controlled, multicenter international trial with a prospective design on one cohort of patients.
A prospective study to evaluate the feasibility of a new treatment algorithm to increase depth of focus after wavefront-guided LASIK correction of myopic refractive errors with the iDesign Advanced Wavescan Studio™ System and Star S4 IR™ Excimer Laser System. The purpose of this study is to determine whether wavefront-guided LASIK correction of myopic refractive errors with CustomVue combined with iDesign 1.3-PRESBY (presbyT-LASIK) treatments mitigate the effects of presbyopia by increasing the depth of focus compared to iDesign CustomVue treatments.
This is a safety, efficacy and pharmacokinetics study of the fixed combination of AGN-199201 and AGN-190584 in participants with presbyopia (inability to focus on items close-up).
