Wear Experience with a Silicone Hydrogel 1-Week Replacement Lens in Current Wearers of a 2-Week Replacement Lens

More frequent replacement of contact lenses may be beneficial for ocular health, but satisfied wearers often have prescriptions renewed in the same lens. This study sought to evaluate the wear experience of a newly released 1-week replacement lens among currently satisfied wearers of a 2-week replacement lens.

This open-label, non-comparative study of single vision lenses recruited satisfied wearers of senofilcon A and refit them in serafilcon A. Participants wore the study lenses for two weeks. Assessments included visual acuity and surveys regarding wear experience: the Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8); visual analog scale (VAS) ratings of vision quality and comfort; VAS ratings of vision and comfort during a variety of activities; and ratings of convenience, satisfaction and ease of use on a 0 to 10 Likert scale.

Sixty-two participants completed the study. Median (interquartile range) distance LogMAR acuity with the study lenses was -0.15 (0.12) OD, -0.16 (0.10) OS, and -0.22 (0.08) OU. The median (IQR) CLDEQ-8 score was 10 (10). Median (IQR) VAS responses were 91 (22) for overall quality of vision and 83 (30), for overall comfort. Median VAS responses regarding specific activities ranged from 87 to 91 for vision and 81 to 90 for comfort. Median (IQR) ratings were 8 (2) for convenience, 10 (1) for ease of use, and 9 (2) for satisfaction.

In this study, satisfied wearers of a commonly prescribed 2-week replacement soft contact lens reported median wear experience VAS scores in the upper quartile for all assessments of vision and comfort and a median CLDEQ-8 score below that associated with dryness. Findings suggest that these lenses are a viable option for practitioners interested in the weekly replacement modality of soft lenses.
