Analysis of Daily Visual Habits in a Presbyopic Population

Area of Science:

• Ophthalmology
• Vision Science
• Biomedical Engineering

Background:

• Presbyopia, an age-related condition, affects near vision and impacts daily activities.
• Understanding visual habits is crucial for effective presbyopia correction strategies.
• Intraocular lens (IOL) implantation is a common surgical option for presbyopia.

Purpose of the Study:

• To evaluate and report the visual habits and requirements of presbyopic patients.
• To assess visual behavior using an advanced sensor system.
• To gather data for optimizing presbyopia-correcting IOL outcomes.

Main Methods:

• A transversal study involving 40 presbyopic patients candidates for IOL surgery.
• Comprehensive ophthalmological examinations including visual, refractive, and biometric analyses.
• Utilized the Vivior Monitor system for over 36 hours to capture visual behavior data.

Main Results:

• Patients dedicated mean percentages of time to distance (27.25%), intermediate (30.23%), and near vision (42.53%).
• Visual activities were performed under photopic (37.08%), mesopic (33.65%), and scotopic (29.28%) conditions.
• Digital screen time ranged from 2% to 48%; age correlated with distance vision and photopic activity duration.

Conclusions:

• Presbyopic visual habits vary significantly in terms of distance, illumination, and activity type.
• A trend towards increased time spent on intermediate and near vision under photopic/mesopic conditions was observed.
• Careful interpretation of sensor data is advised pending further device validation.
