Purpose
To evaluate and report the visual habits and working distance requirements of a sample of Cataract refractive candidates using an advanced sensor.
Setting
Hospital da Luz, Lisboa, Portugal
Methods
Transversal study collecting clinical data from 40 patients with mean age of 61.0 years (43-80 years). A complete ophthalmological examination was performed in all patients including visual, refractive, an ocular biometric analysis. Furthermore, patients were instructed about the use of the Vivior Monitor system (Vivior AG, Zürich, Switzerland), This device was worn for a period of at least 36 hours or more. The data collected was transferred to a database and analyzed.
Results
Mean percentages of time dedicated to distance, intermediate and near vision were 27.25±11.93% (5-65%), 30.23±9.36% (12-50%), and 42.53±14.96% (13-78%), respectively. Mean percentages of time performing activities under photopic, mesopic and scotopic conditions were 37.08±23.20% (5-87%), 33.65±13.84% (6-67%), and 29.28±17.03% (4- 65%). Likewise, the percentage of time using mesopic conditions was correlated with the time associated to distance (r=0.384, p=0.015) and near vision (r=-0.339, p=0.032).
Conclusions
Distance and illumination conditions used to perform different daily life visual activities vary significantly among presbyopes, with a trend to the dedication of more time to intermediate and near visual activities performed under photopic and mesopic conditions.
