Outcome Measures

Primary Outcomes (2)

  • Lens Comfort

    \>0 = comfortable, \<0 = uncomfortable; a weighted combined score calculated from individual comfort-related questions was used to derive comfort outcomes.

Eligibility Criteria

Age18 Years - 39 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • The subject must be at least 18 and less than or equal to 39 years of age and have a need for vision correction in both eyes.
  • The subject must require a lens power between -1.00 to -6.00D and have no more than 1.00D of corneal cylinder.
  • The subject, based on his/her knowledge, must be in good general health.
  • The subject must be able and willing to adhere to the instructions set forth in this protocol and complete all specified evaluations.
  • Subject must be a current adapted daily wearer of soft contact lenses with at least 6 months of CL wear.
  • Subject must agree to wear their contact lenses in both eyes on a daily wear schedule for at least 8 hours per day every day during the study.
  • Subject must be willing and able to use only the care systems and lubricating drops provided for the study during the 4 week period.
  • The subject must read, indicate understanding of and sign the Informed Consent Form.

You may not qualify if:

  • The subject is a rigid gas permeable (RGP) or daily disposable lens wearer.
  • The presence of clinically significant (grade 3 or 4) anterior segment abnormalities; inflammations such as iritis; or any infection of the eye, lids or associated structures.
  • The presence of ocular or systemic disease or need for medication which might interfere with contact lens wear or which would cause the lenses to be removed more than twice a day. (i.e., Sjogren's syndrome, type II diabetes, etc.)
  • Slit lamp findings that would contraindicate contact lens wear such as:
  • pathological dry eye or associated findings
  • pterygium or corneal scars within the visual axis
  • neovascularization equal to or greater than 1mm in from the limbus
  • history of giant papillary conjunctivitis (GPC) worse than grade 2
  • anterior uveitis or iritis (past or present)
  • seborrhoeic eczema
  • seborrhoeic conjunctivitis
  • A history of recurrent erosions, corneal infiltrates, corneal ulcer or fungal infections.
  • A known history of corneal hypoesthesia (reduced corneal sensitivity).
  • Contact lens snellen visual acuities (VA) worse than 20/30.
  • Aphakia, keratoconus or a highly irregular cornea.
  • +2 more criteria
