Outcome Measures

Primary Outcomes (1)

  • Subjective Visual Acuity

EXPERIMENTAL

Participants will wear the Test Lenses in both eyes for one week and then cross over to the Control Lenses in both eyes for one week.

Device: Lens A (kalfilcon A)

Lens B then Lens A

EXPERIMENTAL

Participants will wear the Control Lenses in both eyes for one week and then cross over to the Test Lenses in both eyes for one week.

Device: Lens B (stenfilcon A)

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • They are at least 18 years of age.
  • They understand their rights as a research participant and are willing and able to sign a Statement of Informed Consent.
  • They habitually use soft contact lenses (multifocal soft contact lenses, sphere lenses for monovision, or sphere lenses for distance vision correction and spectacles for near vision correction,) and have worn lenses at least 3 days a week for at least the past six months.
  • They have a minimum reading add of +0.75DS (based on their spectacle refraction)
  • They have spherical equivalent refractive error between +6.00 to -10.00DS at the corneal plane and refractive astigmatism of no greater than -0.75DC in each eye.
  • They are able to achieve distance HCHL visual acuity of +0.10 logMAR or better in each eye.

You may not qualify if:

  • They have an ocular disorder which would normally contra-indicate contact lens wear.
  • They have a systemic disorder which would normally contra-indicate contact lens wear.
  • They are aphakic.
  • They have had corneal refractive surgery.
  • They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
