Abstract: Purpose To refit contact lens (CL) dropouts who dropped out of CLs because of dryness or discomfort into TOTAL30® (lehfilcon A) monthly, spherical CLs to determine the frequency that they can be comfortably refit into CLs. Methods A 6-month, 4 visit, multi-center study was conducted. Adult, 18- to 40-year-old, past CL wearers who dropped out of CLs within the past 2 years because of discomfort or dryness were enrolled. Participants were required to have no dry eye symptoms (SPEED scores ≤ 3). All participants were then fit in TOTAL30® CLs. The participants were evaluated with the SPEED, a comfort visual analog scale (VAS; 0-100 scale), and a Likert questionnaire. Result This study enrolled 61 participants who had a median (interquartile) age of 28 (7) years (78.7% female). This study had a CL retention rate of 98.4% at 1 month and 65.6% at 6 months. The VAS yielded a median comfort score of 81 (40) at 6 months. The Likert questionnaire found that 80.7% of participants would recommend the CLs to a friend at 6 months. SPEED scores increased statistically post-resuming CL wear (p = 0.0001) at 1 month, yet this symptoms change was unlikely clinically meaningful. Conclusions This study found that previous CL wearers who had dropped out of CLs could be comfortably refit with lehfilcon A monthly silicone hydrogel CLs, with the majority of them continuing to wear the CLs at 6 months. The results suggest that the monthly soft CLs with water gradient technology can be a viable option for many CL dropout suffers.
