Presbyopia Clinical Trial

Official title: Development and Validation of a Computer-based Digital Near-vision Optotype Based on the Greek Version of the Print MNREAD.

Status Completed

Clinical Trial Summary

Primary objective of our study is to develop and validate a computer-based digital near-vision optotype based on the Greek version of the print MNREAD.

Clinical Trial Description

Present study aims to develop and validate a computer-based digital near-vision optotype based on the Greek version of the print MNREAD.

Specifically, it aims to evaluate the level of agreement between the conventional printed greek MNREAD chart and the corresponding digital chart, as well as test-retest reliability of the digital optotype.

To address these aims, four reading parameters measured with the print and the digital version are compared. These parameters are the following:

1. Reading Acuity (RA)

2. Maximum Reading Speed (MRS)

3. Critical Print Size (CPS)

4. Accessibility Index (ACC)

All the comparisons take place in two groups: a) a Normal Vision Group (NVG), and b) a Low Vision Group (LVG) in order to estimate the reading capacity in a population with a wide range of vision. ;
