Prospective study to evaluate the clinical performance of fanfilcon A toric contact lens and senofilcon A toric contact lens after two weeks of wear.

The aim of this prospective study is to evaluate the clinical performance of Avaira Vitality toric and ACUVUE OASYS® for ASTIGMATISM contact lenses after 2-weeks of wear in each pair.

Inclusion Criteria:

• Is between 18 and 40 years of age (inclusive)
• Has had a self-reported visual exam in the last two years
• Is an adapted soft contact lens wearer
• Has a contact lens spherical prescription between +6.00 to - 9.00 (inclusive)
• Have no less than -0.75D of astigmatism and no more than -2.25 D in both eyes.
• Can achieve best corrected spectacle distance visual acuity of 20/25 (0.10 logMAR) or better in each eye.
• Can achieve a distance visual acuity of 20/30 (0.18 logMAR) or better in each eye with the study contact lenses.
• Has clear corneas and no active ocular disease
• Has read, understood and signed the information consent letter.
• Patient contact lens refraction should fit within the available parameters of the study lenses.
• Is willing to comply with the wear schedule (at least 5 days per week, > 8 hours/day assuming there are no contraindications for doing so).
• Is willing to comply with the visit schedule

Exclusion Criteria:

• Has a CL prescription outside the range of the available parameters of the study lenses.
• Has a spectacle cylinder less than -0.75D or more than -2.50 D of cylinder in either eye.
• Has a history of not achieving comfortable CL wear (5 days per week; > 8 hours/day)
• Has contact lens best corrected distance vision worse than 20/25 (0.10 logMAR) in either eye.
• Presence of clinically significant (grade 2-4) anterior segment abnormalities
• Presence of ocular or systemic disease or need of medications which might interfere with contact lens wear.
• Slit lamp findings that would contraindicate contact lens wear such as:
• Pathological dry eye or associated findings
• Pterygium, pinguecula, or corneal scars within the visual axis
• Neovascularization > 0.75 mm in from of the limbus
• Giant papillary conjunctivitis (GCP) worse than grade 1
• Anterior uveitis or iritis (past or present)
• Seborrheic eczema, Seborrheic conjunctivitis
• History of corneal ulcers or fungal infections
• Poor personal hygiene
• Has a known history of corneal hypoesthesia (reduced corneal sensitivity)
• Has aphakia, keratoconus or a highly irregular cornea.
• Has Presbyopia or has dependence on spectacles for near work over the contact lenses.
• Has undergone corneal refractive surgery.
• Is participating in any other type of eye related clinical or research study.

A total of 45 subjects were enrolled. One participant was ineligible for the study due to an unacceptable lens fit at the first visit. A total of 44 subjects were dispensed and completed all study visits.
