The purpose of this study was to compare the clinical performance of two fitting approaches for multifocal contact lenses.
This was a prospective, cross-over, double-masked (participants and investigator), randomized order of testing study. It compared two fitting approaches for silicone hydrogel multifocal contact lenses to assess which method achieved greater vision satisfaction and performance.

Overall Vision Satisfaction
Overall vision satisfaction for each lens was measured on a 0-100 point Visual Analog Scale (VAS), where 0=Extremely Unsatisfied and 100=Extremely Satisfied
Time frame: One week
Overall Lens Preference
Participants selected their preferred lens fitting approach from options - 'Control', 'Test', or 'No Preference'
Time frame: Two weeks
Overall Binocular Visual Acuity Index
Mean binocular visual performance for each lens was measured by timed logMAR charts. Overall binocular logMAR visual acuity index was calculated by taking the mean of distance and near visual acuities
Time frame: One week
Number of Contact Lenses
This measured the ease of fitting each contact lens. It counted the number of contact lenses (pair), selected as per the fitting guide, used to determine the final contact lens to dispense.
Time frame: One week
