Clinical Performance of Verofilcon A Toric Contact Lenses

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.

Impact of TRYPTYR on a Patient's Quality of Life and Ability to Perform Work

This 1-month, 3-visit study will be conducted at the Southern College of Optometry (Memphis, TN), Kannarr Eye Care, LLC (Pittsburg, KS) and Complete Eye Care of Medina (Minneapolis, MN). Adults ≥18 years of age who have been diagnosed with DED for at least 6 months and who are currently symptomatic (Eye Dryness VAS Score ≥40) will be recruited. Subjects will have an abnormal Schirmer test of \<10 mm/5 min. Subjects will also be required to score ≤70 on the IDEEL Quality of Life (QoL) Work domain to ensure that their DED symptoms are significantly impacting their ability to do work.9 Subjects will be required to have corrected distance visual acuity of 20/32 (0.2 logMAR) or better.

Switching From Restasis to TRYPTYR

Switching to acoltremon 0.003% will significantly improve the signs and symptoms of participants who were being treated with Restasis at 28 days post-treatment compared to baseline. Dry eye disease (DED) is a prevalent condition that commonly affects patients of working age in addition to the elderly. DED is a complex condition that results in ocular symptoms such as dryness and burning and signs such as decreased tear production (aqueous deficient DED) or increased tear evaporation (evaporative DED). Unfortunately, there is not a perfect correlation between DED signs and symptoms, which makes diagnosis and timely treatment challenging.
