Which contact lens fits better? small study compares two toric lenses
NCT ID NCT06431061
First seen Jun 26, 2026 ยท Last updated Jun 26, 2026
Summary
This study compared how well two types of toric contact lenses (Proclear Toric and Biofinity Toric) fit in people with astigmatism. Thirty-seven adults who already wear toric lenses tried each lens for 15 minutes. The goal was to see which lens had a better fit. The study is complete and provides information on short-term lens performance.

Inclusion Criteria: 1. Are at least 17 years of age and has full legal capacity to volunteer. 2. Have understood and signed an information consent letter. 3. Are willing and able to follow instructions and maintain the appointment schedule. 4. Are an adapted soft toric contact lens wearer. 5. Do not habitually wear either of the two study lens types. 6. Have a vertex-corrected contact lens prescription with a spherical component of +4.00D to -9.00D in combination with astigmatism of no less than -0.75D and no more than -2.25D in each eye. 7. Can achieve best corrected distance visual acuity of +0.10 logMAR (subjective refraction) or better in each eye. 8. Can be fitted with and achieve a distance visual acuity of +0.18 logMAR or better in each eye with the study contact lenses. Exclusion Criteria: 1. Are participating in any concurrent clinical or research study. 2. Have any known active ocular disease and/or infection or slit lamp findings that would contraindicate contact lens use. 3. Have a systemic condition that in the opinion of the investigator may affect a study outcome variable. 4. Are using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable. 5. Have known sensitivity to the diagnostic pharmaceuticals to be used in the study. 6. Have a history of not achieving comfortable CL use (5 days per week; \> 8 hours/day) 7.
