Active clinical trials for "Presbyopia"

The G4 Multi multifocal contact lens is a soft contact lens intended to correct far, intermediate, and near vision for individuals with presbyopia. The lens covers the cornea and part of the sclera. The lenses can be used for daily wear for up to 1 year.

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.

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 clinical trial is to assess the clinical performance of LID# 223194 Multifocal (MF) contact lens and a commercially available Air Optix plus HydraGlyde (AOHG) MF contact lens. Eligible subjects will wear each study lens type in a cross-over fashion as randomized for approximately 2 days.

Subjects will evaluate each study lens in a random order. The lenses will be worn in both eyes for a short period.

This study is to evaluate the product performance of the investigational LD127025 MF mid add soft contact lens compared to CIBA Vision's Air Optix Aqua MF MED add soft contact lenses when used among currently adapted soft contact lens wearers.

The purpose of this study was to compare binocular high contrast, high illumination (HC/HI) visual acuity at near (40 centimeters) of new multifocal contact lenses against AIR OPTIX® AQUA MULTIFOCAL contact lenses when worn for 9 hours.

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 compare an alternative fitting guide to a current fitting guide for optimizing contact lens parameters and determining contact lens prescription.

The purpose of this observational, non-controlled, multicenter trial with a retrospective design is to evaluate the visual performance of one cohort of patients who received the EDOF MINI WELL® intraocular lenses following refractive lens exchange (RLE) or cataract surgery.
