Clinical Performance of Verofilcon A Toric Contact Lenses

TOTAL30® Multifocal Toric contact lenses (CLs) are a 1-month, silicone hydrogel (lehfilcon A), studies have likewise found the lehfilcon A material to provides a comfortable wearing experience for the full life of the CL and for the full CL wear day.1 While initial TOTAL30 data are promising, the literature currently lacks data directly related to the Total30 MFT design and a targeted study aimed at evaluating how Total30 MFT performs with regards to overall comfort, vision, and satisfaction for those who are previous reusable toric CL wearers and are now presbyopic. This transition could be particularly important for patients who are presbyopic and astigmatic given that these two patients groups tend to struggle more with CLs than spherical CL wearers. Thus, the purpose of this work is to determine Total30 MFT overall comfort, vision, willingness to remain in CLs after the study, and satisfaction for those who currently wear reusable silicone hydrogel toric CLs and are now presbyopic. These data will provide valuable information to partitioners for patient educational purposes, and it will provide credence for refitting presbyopic patients who have astigmatism into Total30 MFT, especially after the onset of presbyopia.
