Dailies Total 1 Sphere Contact Lenses

Completed · Not applicable

Conditions studied: Dry Eye, Contact Lens Complication

In brief

CL discomfort is a complex phenomenon that has been defined by the Tear Film and Ocular Surface Society in their seminal report on contact lens (CL) discomfort as a condition that results in "episodic or persistent adverse ocular sensation related to lens wear, either with or without visual disturbance resulting from reduced compatibility between the CL and the environment, which can lead to decreased wearing time and discontinuation of CL wear." A recent review by Pucker and Tichenor found that CL discomfort was the top reason for established CL wears to cease wearing CLs. This same review alarmingly found that the frequency of CL dropout was about 20% across the many studies aimed at evaluating this condition, which is surprising given the introduction of better soft CL materials and daily disposable CLs over the past 20 plus years. Dailies Total1 (DT1), which is a relatively new daily disposable CL, is a commonly used trouble shooting CL for patients who have failed with other CLs because DT1 utilizes advanced material technology that is specifically aimed at improving CL comfort. While DT1 is commonly used in these struggling patients, the literature currently lacks a targeted study aimed at understanding the frequency of successfully refitting CL dropouts into this advanced CL. Thus, the purpose of this study is to determine the frequency that past CL wearers who failed because of dryness or CL discomfort who can comfortable wear DT1.
