OBJECTIVE:To investigate whether initial assessment of contact lenses prescribed for myopia control (MC) predicts short-term visual performance.
METHOD:Retrospective analysis of 43 participants in a double-masked, randomized, cross-over trial wearing at least one lenssingle-vision (SV) lens (1-DAY ACUVUE MOIST) or MC lenses (MiSight or Proclear Multifocal-Distance +2.00D). Participants completed questionnaires at the fitting visit, a take-home questionnaire (THQ) 3 days after fitting and finally at the assessment visit (≥5 days after fitting). Questions comprised vision clarity and lack of ghosting (distance, intermediate, near at day/night time); vision stability; driving vision; overall vision satisfaction and comfort (1–10 scale, 1-point steps); and willingness to purchase based on vision and MC benefit of lens (yes/no response). Visual acuity was measured at fitting and assessment visits.
RESULTS:Vision clarity (intermediate and near) was significantly worse at assessment compared with fitting while wearing MC lenses (P<0.001), as was overall vision satisfaction (P<0.001), comfort (P<0.001), and vision stability (P=0.001) while wearing either SV or MC lenses. Participants willing to purchase at assessment visit was 84% with SV and 36% with MC lenses, increasing to 88% (SV, P=1.00) and 61% (MC, P<0.001) if the lenses slowed myopia progression. Visual acuity was no different with either MC or SV lenses at fitting or assessment (P≥0.251).
CONCLUSION:Initial performance at fitting did not predict short-term performance for SV or MC lenses. A significant increase in willingness to purchase if lenses slowed myopia progression was observed while wearing MC lenses. Educating patients on the benefits might increase acceptability of MC lenses.
