Refitting Previous Presbyopic Contact Lens Dropouts with a Single Use Multifocal Contact Lens

Contact lens dropout is known to occur frequently in presbyopic patients. The purpose of this study was to assess the rate of patient-reported success, defined by willingness to continue lens wear after the study, when fitting previous presbyopic contact lens dropout patients with a single-use multifocal contact lens.

Presbyopes who had previously discontinued contact lens wear due to poor vision were recruited and fit with delefilcon A multifocal contact lenses. Participants were prescribed lenses following the fitting guide, wore lenses for 1 week to allow for adaptation, and returned for a follow-up visit. After confirmation of optimized lens powers, lenses were dispensed for one month of wear. A final visit was completed to assess vision and respond to survey questions, including 0-100 visual analog scale (VAS) surveys of lens wear experiences. Participants also scored their likelihood of continuing with study lenses upon study completion and whether the participant would recommend the study lenses to a friend. Success with fitting the study lenses was defined as those participants who selected "very likely" or "likely" to continue wearing the study lenses after the conclusion of the study.

Twenty-five participants completed all study visits. Median (Interquartile range) binocular LogMAR acuity with the study lenses was -0.10 (0.16) at distance (20/16 Snellen acuity equivalent) and 0.00 (0.12) at near (20/20 Snellen acuity equivalent). The median (IQR) satisfaction score was 84 (29.75) on a scale of 0-100. Eighty percent of the participants said they were very likely or likely to continue wearing the multifocal lenses after the conclusion of the study. All twenty-five of the participants said they would recommend the study lenses to a friend.

The objective and subjective findings of this study suggest that presbyopic contact lens dropouts can be refit with the study multifocal contact lens.
