Optimizing Toric Contact Lenses for Astigmatism

This study is looking for volunteers to help evaluate how well different toric contact lenses correct astigmatism (a common vision problem causing blurry vision). You would wear two types of contact lenses, stenfilcon A and comfilcon A, for 15 minutes each day. Researchers will compare your subjective experience (how well you feel you see) with objective measurements to see which lens provides the best correction. To join, you need to be at least 18 years old and have a specific range of nearsightedness, farsightedness, or astigmatism. The study aims to enroll 45 participants, but its current recruitment status is unclear.

Study design
This interventional study plans to enroll 45 participants. It compares two different contact lenses.
What's involved
You would wear each contact lens (stenfilcon A and comfilcon A) for 15 minutes daily. The study measures your vision at the end of this 15-minute period.
Compensation
Not stated in the trial record.
Follow-up
Your vision will be assessed at the end of the 15 minutes of daily wear for each lens.

  • Subjective assessment of optimization of Toric lensesAt the End of Baseline 15 minutes of daily wear

    Proportion of eyes in which the optimized toric lens cylinder axis determined by the subjective method agrees with that determined by the objective method within ±10 degrees (measured at a single time point).
