T30 for Astigmatism in Digital Device Users

Status Active, not recruiting

Clinical Trial Summary

This study aims to determine if Total30 lenses for astigmatism can be successfully fit in participants who are heavy digital device users.

Clinical Trial Description

Extensive computer use is no longer an employment-specific challenge. Use of digital devices in work, home, and leisure settings is now the norm, and it is now socially expected. While the introduction of high-powered computers and digital devices have greatly improved many aspects of modern life, the pervasive use of digital devices has caused some patients to develop a condition known as Digital Eye Strain (DES). DES has been reported to be as high as 93% the population depending upon how the condition is defined, and its severity has been found to increase with increased digital device time. DES is a condition where patients experience symptoms such as glare, accommodative dysfunction, defocus, fatigue, discomfort, and dryness from digital device use, and these dry eye symptoms may also result in decreased quality of life. While dryness symptoms in DES are likely multifactorial (e.g., contact lens use, systemic disease status), much of the dryness symptoms in DES are probably due to tear film evaporation secondary to having a reduced number of blinks per minute while using digital devices. Contact lens (CL) discomfort affects most CL wearers with discomfort consistently topping the reasons why established CL wearers drop out of CLs. In fact, studies have consistently found that the frequency of CL dropout is around 20% with this dropout frequency staying relatively stable over the past 20 plus years. This static frequency of CL dropout is surprising since there have been a number of dramatic soft CL innovations during this time frame (e.g., widely available daily disposable CLs, silicone hydrogel CL materials with high oxygen transmissibility, new CL surface coatings). CL discomfort and dropout could be affected by significant time spent on digital devices and DES. Maintaining ocular comfort with satisfactory CL performance (comfort, lack of dryness, and overall good vision) is key to overall success. This could be especially important in patients who wear astigmatic CLs, yet the community currently lacks data on this topic. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
