An interventional study of Total 30 multi foric contact lenses in Contact Lenses and Presbyopia, sponsored by Southern College of Optometry. Recruiting at 1 site in United States. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-05-14.

The goal of this clinical trial is to [primary purpose: is to determine if Total30 Multi focal toric conntact lensesare comfortable and the willigness for those who have previously worn reusable toric contact lenses are willing to stay in Total30 MFT after 1 month of wear during the duration of the study. Healthy previous reusable toric contact lens weareres will be refit into total30 MFT contact lenses and will be asked to gauge their comfort while wearing the lenses. Healthy adult participants who are presybyopic between the ages of 18-40 can participant, sex and gender are not disqualifiers unless the participant is pregnant or breast feeding. The main question[s] it aims to answer [is/are]
[primary hypothesis or outcome measure 1Proportions of toric CL wearers who have positive visual acuity scores in comfort and vision after one month of wear.
[primary hypothesis or outcome measure 2]? Contact lens dry eye-8 scores will be less than 12 indicating high levels of comfort after one month of wear.
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.
