Study Type: Interventional

Official Title:

Brief Summary: This study will evaluate the fitting characteristics and physiological response of two toric lenses manufactured by Vistakon.

Detailed Summary:
Sponsor: Johnson & Johnson Vision Care, Inc.

Current Primary Outcome:

  • Assessment of Conjunctival Hyperemia in Subjects That Are High Myopes (Have a High Degree of Nearsightedness) [ Time Frame: after 6 hours of wear ]
    Conjunctival hyperemia measures the redness across the white of the eye. The investigator used a grading scale of 0=none, 1=slight, 2=moderate, 3=severe.
  • Assessment of Conjunctival Hyperemia in Subjects That Are Hyperopes (Farsighted) [ Time Frame: after 6 hours of wear ]
    Conjunctival hyperemia measures the redness across the white of the eye. The investigator used a grading scale of 0=none, 1=slight, 2=moderate, 3=severe.
  • Assessment of Conjunctival Hyperemia in Subjects That Are Oblique Astigmats (Have an Abnormally Curved Cornea) [ Time Frame: after 6 hours of wear ]
    Conjunctival hyperemia measures the redness across the white of the eye. The investigator used a grading scale of 0=none, 1=slight, 2=moderate, 3=severe.
  • Assessment of Limbal Hyperemia in Subjects That Are High Myopes (Have a High Degree of Nearsightedness) [ Time Frame: after 6 hours of wear ]
    Limbal hyperemia measures the redness around the edge of the cornea. The investigator used a grading scale of 0=none, 1=slight, 2=moderate, 3=severe.
  • Assessment of Limbal Hyperemia in Subjects That Are Hyperopes (Farsighted) [ Time Frame: after 6 hours of wear ]
    Limbal hyperemia measures the redness around the edge of the cornea. The investigator used a grading scale of 0=none, 1=slight, 2=moderate, 3=severe.

    • Original Primary Outcome: Physical fit [ Time Frame: after 6 hours of wear ]

    Current Secondary Outcome:

    Original Secondary Outcome: Physiology. [ Time Frame: after 6 hours of wear ]
