NCT ID: NCT04739085 Recruiting - Presbyopia Clinical Trials

Level of Agreement Between Clinical Defocus Curves and the Web-based Democritus Digital Acuity Reading Test wDDART

Start date: November 20, 2020
Phase:
Study type: Observational [Patient Registry]

The primary objective of this study is to compare the level of agreement between clinical defocus curves and the web Democritus Digital Acuity Reading Test (wDDART), which is a web-based digital near and intermediate vision reading test.

NCT ID: NCT04059289 Completed - Pseudophakia Clinical Trials

Intermediate Vision in a Driving Simulator Environment: Comparison of the J&J EYHANCE With a Conventional Monofoc. IOL

JJ-EYHANCE
Start date: January 7, 2020
Phase:
Study type: Observational

To compare (low contrast) visual acuity (VA) and contrast sensitivity (CS) - both at intermediate distances under nighttime driving conditions in a driving simulator between patients with bilateral EYHANCE IOLs OR bilateral conventional monofocal IOLs. Visual function testing in the driving simulator will be assessed without AND with (static) glare. Additionally: Assessment of individual response times, scanpath characteristics, evaluation of test retest reliability and self-evaluation of (intermediate) vision and visual impairment related to glare.

NCT ID: NCT03457441 Completed - Near Vision Clinical Trials

TIL-001
Start date: March 20, 2018
Phase: N/A
Study type: Interventional

This study evaluates the level of agreement between visual parameters tested using OdySight, a mobile application, and standards in office methods.
