Purpose

The primary objective of this study is to develop and validate an experimental lighting facility that allows the evaluation of near and intermediate vision in different user-defined illuminance levels.

Setting

Department of Ophthalmology, University Hospital of Alexandroupolis, Alexandroupolis, Greece

Methods

This is a prospective, randomized, controlled study. Normophakic patients populated three validation groups (VGs) according to their binocular uncorrected near visual acuity (UNVA):  a) VG1: 0.0 to 0.1 logMAR, b) VG2: 0.4 logMAR, and, c) VG3: 0.7 logMAR. All participants addressed 10 near and intermediate activities of daily life (ADLs) in the three following lighting settings: 1) 25fc/3000K, 2) 50fc/4000K, 3) 75fc/6000K

Results

Thirty patients in each group performed all ADLs in the three lighting settings. VG1 demonstrated the best ADL scores in all ADLs and lighting settings, followed by the VG2. VG3 presented the worst scores. ADLs using printed material showed significant differences among the three lighting settings for all study groups, while ADLs using screens or needing manual dexterity demonstrated no significant differences except for ST in VG1. All ADL scores demonstrated high correlation with UNVA in all lighting settings (p < 0.001).

Conclusions

This is the first study that validates a lighting facility for comparative studies in patients with different near vision capacity performing a series of ADLs. This facility could be used in future studies for the evaluation of near and intermediate vision, in different illuminance levels, of presbyopic patients and of patients following lens extraction surgery with implantation of premium intraocular lenses.
