Comfort After Refitting Symptomatic Habitual Reusable Toric Lens Wearers with a New Daily Disposable Contact Lens for Astigmatism.

ABSTRACT:

Purpose

To subjectively evaluate comfort with a daily disposable (delefilcon A for astigmatism) contact lens compared to other common weekly/monthly soft toric contact lenses in symptomatic wearers.

Methods

This open-label, single arm study enrolled current reusable soft toric lens wearers with minimum score of 12 on the contact lens dry eye (CLDEQ-8) questionnaire. Subjects were also administered the CLDEQ-8 after 1 replacement schedule of their optimized habitual toric lenses (2 to 4 weeks), and after 2 weeks of wear with delefilcon A toric daily disposable lenses (Dailies Total1 for Astigmatism; Alcon Vision LLC, Fort Worth, Texas).

Results

A total of 85 subjects completed the study. Mean total CLDEQ-8 score was 16.8 ± 8.1 for subjects refit with their optimized habitual toric lenses and 12.4 ± 7.5 for subjects refit with delefilcon A toric lenses, a difference of 4.3 ± 10.4 (p < 0.001). With delefilcon A toric lenses, 78.9% of subjects reported little to no intensity of eye discomfort, compared to 51.7% for the habitual toric lenses (p = 0.005). In addition, 77.7% of subjects reported little to no intensity of dryness for delefilcon A toric lenses, compared to 50.6% for the habitual toric lenses (p = 0.001).

Conclusion

The subjective comfort in symptomatic habitual reusable toric contact lens wearers was improved by refitting with delefilcon A toric lenses.

Project description:ObjectiveThe purpose of this study was to evaluate the wear experience of satisfied wearers of a particular reusable toric soft contact lens when refit into a water surface technology daily disposable toric soft contact lens.Methods30 participants completed the study over three visits. At the first visit, subjects were refit into with their habitual reusable toric soft contact lens (comfilcon A) to maximize fit and vision. Subjects returned after one week and were then refit into the study daily disposable soft contact lenses (verofilcon A) and completed surveys of their initial impressions of comfort, vision, and satisfaction. Participants wore the study lenses for two weeks, and then returned for their final visit to complete a vision and ocular health check. At the final visit, subjects also completed surveys to rate their overall and end-of-day comfort, quality of vision, stability of vision, and dryness using a visual analog scale (VAS). Participants also answered questions about their wear experience with the lenses. Overall median and interquartile range (IQR) of all data and surveys was calculated.ResultsInitial impressions of the study lenses revealed a median (IQR) score of 85 (28) for vision, 91 (25) for comfort, and 87 (21) for satisfaction. Overall VAS scores after two weeks of wear found median scores of 93 (16) for quality of vision, 88 (28) for stability of vision, and 91 (20) for comfort. End-of-day median scores were 82(27) for quality of vision, 90 (35) for stability of vision, and 80 (38) for comfort. Overall dryness scores were 20(45) and end-of-day dryness was 39 (46). Median(IQR) binocular logMAR visual acuity with the study lenses was -0.16(0.1). Median rotation of the lenses was 0(4.3) degrees.ConclusionParticipants wearing the daily disposable study lenses for astigmatism gave high scores in vision and comfort both at initial fitting and after two weeks of lens wear. Results showed that satisfied wearers of comfilcon A reusable toric soft contact lenses can be successfully refit with verofilcon A daily disposable contact lenses.

Project description:PurposeTo investigate whether carrying out various interventions part way through the day influences comfort in symptomatic daily disposable (DD) contact lens wearers.MethodsA subject-masked, randomized, controlled clinical trial was conducted in thirty symptomatic soft lens wearers who wore their habitual DD contact lenses bilaterally for 12 h on two separate days. Five hours after lens application, one of the following three interventions or a control was performed on each eye: replacing the existing lens with a new lens; removing and reapplying the same lens; performing a 'scleral swish'; and no action (control). Comfort scores were recorded using SMS text messages every hour following lens application using a 0 (causes pain) to 100 (excellent comfort) scale. Comfort scores before lens application, at 6 mins post-application, and at 6 mins post-intervention were also recorded.ResultsThere was a significant reduction in comfort from pre-lens application to 6 mins post-application for all groups (all p<0.05). Comfort gradually decreased from 6 mins to 5 h after lens application for each group (p<0.0001) with no significant difference between groups over the 5-h period (p = 0.09). There was no significant difference in comfort 6 mins post-intervention for any group (all p>0.05). After the intervention, comfort continued to decline (p<0.0001) with slightly lower mean scores for the control group compared to the new lens group (p = 0.003). Change in comfort relative to pre-intervention (5 h) was similar for all groups (p = 0.81). There was no difference in comfort at 12 h between groups (p = 0.83).ConclusionThis work has confirmed that comfort shows a continual and significant decline over a 12-h wearing period in symptomatic DD contact lens wearers. None of the interventions investigated had any significant impact on end-of-day comfort. These data suggest discomfort in lens wearers is more heavily influenced by changes to the ocular environment rather than to the lens itself.Trial registrationControlled-Trials.com ISRCTN10419752 http://www.controlled-trials.com/ISRCTN10419752.

Project description:IntroductionSoft contact lens wearers are often prescribed the same lens material and modality for multiple years if patients express satisfaction and no significant problems with lens fit or ocular health are noted upon evaluation. Despite their satisfaction, it is possible that other lenses exist that could provide additional health or convenience benefits and still provide satisfied lens wear experience.MethodsIn this study, wearers of a specific monthly replacement lens brand (comfilcon A) were recruited for an open-label study. The habitual contact lens prescription was optimized for 2 weeks of wear and participants confirmed that they were satisfied with their habitual lenses before being refit with daily disposable lenses (verofilcon A). Participants responded to visual analog scale (VAS) survey about their initial impressions of the lenses. After 2 weeks of lens wear, participants completed a final study visit and completed surveys about lens wear experiences with the daily disposable study lenses.ResultsFifteen male and 15 female participants completed the study. Median (IQR) binocular LogMAR visual acuity was -0.20(0.12), which is equivalent to 10/12.5 Snellen acuity. Initial impression surveys revealed median (interquartile range) of 92.5(22.3) for quality of vision; 95.0(19.3) for comfort; and 91.5(19.3) for satisfaction. At the final visit, median scores for EOD quality of vision was 86.5(24.0); EOD comfort was 84.5(30.3), and EOD dryness 25.5(47.0). Median overall VAS scores were 92.5(16.0) for vision; 88.0(18.3) for comfort, and 17.5(25.8) for dryness. Median satisfaction with the study lenses was scored 9(2.8) on a 1-10 scale.ConclusionsIn this study, satisfied wearers of comfilcon A reusable lens were refit with Verofilcon A daily disposable lenses and showed high satisfaction scores with the new lenses, showing that refitting these patients can allow patients to have lenses with more frequent replacement and maintain satisfaction with daily lens wear.
