Performance of Daily Disposable Contact Lenses in Symptomatic Wearers
Bibliographic record
Abstract
PurposeTo evaluate the performance of delefilcon A water gradient and narafilcon A silicone hydrogel daily dispos-able contact lenses (CLs) in symptomatic soft CL wearers. MethodsThis multicenter, open-label, crossover study randomized 121 soft CL wearers with symptoms of CL dis-comfort to delefilcon A or narafilcon A for 2 weeks, followed by the alternate lens for 2 weeks. Subjects rated end-of-day (EOD) comfort, EOD dryness, and quality of vision, and investigators rated fit, surface deposits, and surface wettability. ResultsAfter 2 weeks, all subjective measures were better for delefilcon A than for narafilcon A, including EOD comfort (8.3 ± 1.9 vs. 6.6 ± 2.2), EOD dryness (8.0 ± 2.2 vs. 5.8 ± 2.6), and quality of vision (8.9 ± 1.4 vs. 7.9 ± 1.7), all p<.0001. Average daily wear time (DWT; 13.0 ± 2.8 vs. 12.3 ± 2.6 hr) and average comfort-able DWT (11.6 ± 3.9 vs. 9.3 ± 3.8 hr) were longer for delefilcon A lenses (p<.0001). The proportions of right and left lenses without front surface deposits were twofold higher for delefilcon A than for narafilcon A, and surface wettability was significantly higher for delefilcon A than for narafilcon A p<.0001). ConclusionIn this population of symptomatic CL wearers, delefilcon A lenses showed superior subjective ratings for comfort, dryness, quality of vision, DWT, and comfortable DWT and better investigator-rated lens sur-face attributes including fewer surface deposits and superior wettability than did narafilcon A lenses after 2 weeks of wear.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
