This is a prospective randomised open-label study with the aim to compare the visual performance of the trifocal FineVision® IOL versus the extended range of vision Symfony® IOL after phaco-emulsification cataract surgery.
A high-performance smart eyeglasses system with integrated sensing, actuation, control and data collection is being developed at the University of Utah. These smart eyeglasses use tunable lenses and integrated sensor technologies to correct blurred vision caused due to a major age-related condition called presbyopia.The objective of this study is to test this smart system on patients suffering from presbyopia aged 45 and above. The researchers intend to study the effect of these smart eyeglasses by qualitatively investigating the patient's visual acuity with this smart system. The results of this study and subsequent research have the potential to lead to major lifestyle improvements and better treatment for millions of presbyopic patients that are constrained by the limitation of current corrective eyeglass technologies. There are two main sources of fairly well understood problems that lead to presbyopia and loss of the eye focusing function. The adaptive eyeglasses used in these tests do not fix any of the internal eye problems. They just compensate externally for the loss of the eye focusing function caused by presbyopia. As such, the investigators intend to evaluate our system's effectiveness in terms of the sharpness of the perceived images.
This is a 4-visit, multi-center, randomized, double-masked, parallel group study evaluating the safety and efficacy of CSF-1 in the treatment of presbyopia.
This clinical study will evaluate pilocarpine hydrogen chloride (HCl) ophthalmic solution (AGN-190584) in an expanded participant population to establish efficacy, safety, and tolerability versus the vehicle-control when administered, over a 30-day study intervention period, once daily bilaterally in participants with presbyopia.
Prospective, controlled, single-surgeon, single-center clinical study to compare visual acuity outcomes to data obtained in a similar study by the same principal investigator on the trifocal IOL POD F (study no. PHY1802, ClinicalTrials.gov ID: NCT03688425)
This is a prospective single-center study of implantations of the presbyopic version of phakic intraocular lens IPCL (EyeolUK, United Kingdom).
The current study aims to assess the use of pilocarpine and brimonidine to improve near visual acuity in patietns with monofocal intraocular lenses. Thirty-three subjects with be enrolled and baseline visual acuity with be measured at near and distance. This will be compared to visual acuity after drop administration over 6 hours. A quality of life questionnaire will also be evaluated.
The objective of this study is to obtain an additional 36 months of safety and effectiveness data from all subjects who were implanted with the VisAbility™ Micro Insert in the VIS-2014 clinical trial.
The purpose of this study was to assess the effect of topical UNR844-Cl (lipoic acid choline ester chloride) ophthalmic solution on near visual function in presbyopic subjects.
