Purpose : To evaluate the clinical performance of nelfilcon A toric contact lenses.

Methods : The analyses included 94 subjects who wore the nelfilcon A daily disposable contact lens for 1 week. Subjects were asked to rate the study lenses on a scale of 1 to 10. The rating of ‘1’ represented the worst experience and the rating of ‘10’ represented the best experience. The investigator recorded the position of the scribe marks while at the slit-lamp biomicroscope. The degree of offset away from the horizontal meridian was analyzed for each eye. Lens centration and lens fit were also assessed by the investigators, while lens oscillation was observed by the investigator during blink.

Results : The average age of subjects was 35.8 years and 59.6% were female. The mean sphere was -2.82 D and 41.8% of the subjects had a cylinder greater than -1.5 D. Mean insertion comfort ratings at dispense were 9.0 ± 1.3 and mean overall comfort ratings were 8.1 ± 1.7 after 1 week of lens wear. Mean quality of vision ratings at dispense were 8.4 ± 1.5. The average amount of offset was clinically acceptable for the lens at both visits (range of average values: 5.2° to 6.8°). There were no lenses rated as decentered with corneal exposure or unacceptably decentered. At dispense, 98.4% of the lenses had ≤5° oscillation, while 98.9% had ≤5° oscillation after 1 week. At dispense, 100% of the lens fit was rated as optimal or acceptable, and 99.4% was rated optimal or acceptable after 1 week of lens wear.

Conclusions : Overall, subjects and investigators rated the nelfilcon A contact lens high with respect to comfort, quality of vision and lens fit, (including position, centration, oscillation and overall fit). This lens may be a good option for patients who require astigmatism correction and want the convenience of a daily disposable contact lens.
