Trial Summary

What is the purpose of this trial?The purpose of the study is to evaluate the lens fit characteristics of delefilcon A contact lenses with different base curves and diameters.

Eligibility Criteria

This trial is for individuals with refractive errors, such as near-sightedness. Specific eligibility criteria are not provided, but typically participants would need to have a stable prescription and no eye diseases.

Inclusion Criteria

Able to wear contact lenses within a range of sphere powers from -2.00 and -4.00 diopters (D)

Successful wearer of spherical soft contact lenses in both eyes for a minimum of 5 days per week and a minimum of 6 hours per day during the past 3 months

Best Corrected Visual Acuity (BCVA) (with manifest refraction) better than or equal to 0.10 logarithm Minimum Angle of Resolution (logMAR) in each eye

Exclusion Criteria

I don't have eye infections or conditions that prevent wearing contact lenses.

I have had or plan to have eye surgery to correct my vision, or I have an irregular cornea.

My eye exam showed moderate to severe surface eye changes or some blood vessel growth.

Participant Groups

The study is testing Delefilcon A contact lenses. It compares lenses with various base curves and diameters to standard ones, assessing how well they fit.

2Treatment groups

Experimental Treatment

Group I: LID023681, then LID006961Experimental Treatment2 Interventions

Delefilcon A contact lenses with different base curves and diameters worn in Period 1, followed by delefilcon A contact lenses with standard base curves and diameters worn in Period 2. During each period, the contact lenses will be worn bilaterally (in both eyes) for 6 (+2) hours. A one-to-two day washout will separate the wear periods.

Group II: LID006961, then LID023681Experimental Treatment2 Interventions

Delefilcon A contact lenses with standard base curves and diameters worn in Period 1, followed by delefilcon A contact lenses with different base curves and diameters worn in Period 2. During each period, the contact lenses will be worn bilaterally (in both eyes) for 6 (+2) hours. A one-to-two day washout will separate the wear periods.
