Design outcomes

Primary

Measure	Time frame
Binocular uncorrected and corrected visual acuity for far distance, measured using LogMAR scale at baseline, 1 and 3 months	—

Secondary

Measure	Time frame
1. Binocular uncorrected and corrected visual acuity of patients for intermediate and near distance (66 and 40 cm respectively) measured using LogMAR scale at baseline, 1 and 3 months 2. Manifest refraction with spherical equivalent (SE) measured using subjective refraction at baseline, 1 and 3 months 3. Intraocular pressure measured using tonometry (mmHg) at baseline, 1 and 3 months 4. Dysphotopsies evaluated using the McAlinden Quality of Vision (QoV) questionnaire at baseline and 3 months	—
