Overview
Brief Summary
This Randomized Control Trials Study , conducted in Lahore, Pakistan, investigates the comparative efficacy of two approaches-plus lens addition of +0.75 diopters (D) and vision therapy using the HART chart-for managing accommodative infacility. Accommodative infacility, a condition characterized by the eye's reduced ability to adjust focus between distant and near objects, impacts both visual comfort and performance, particularly during prolonged near work.
Detailed Description
The study sample comprises 38 participants, aged 15 to 35 years, divided into two groups: one group receiving plus lens addition of +0.75 D and the other undergoing structured vision therapy with the HART chart. Findings revealed that vision therapy was significantly more effective than plus lens addition, with results showing statistical significance at P \< 0.05.

Outcomes
Primary Outcomes
Monocular and Binocular Accommodative Facility (MAF/BAF)
Time Frame: 12 Months
Improvement in accommodative facility measured using Monocular and Binocular Accommodative Facility (MAF/BAF) tests with ±2.00 D flipper lenses. Measurement is recorded in cycles per minute (cpm).
subjective measures of visual comfort
Time Frame: 12 Months
Reduction in symptoms of accommodative infacility assessed using a customized performa. Measurement is based on a symptom severity score recorded pre- and post-intervention.
