  12. Any Grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) which may contraindicate contact lens wear.
  13. Any ocular infection or inflammation.
  14. Any corneal distortion or irregular cornea.

Åtgärdsbeskrivning
Tidsram
Overall Quality of Vision Using the Contact Lens User Experience (CLUE) TM Questionnaire
Tidsram: 8 -12 days post wear
CLUE Overall Quality of Vision is assessed using the Contact Lens User Experience (CLUE)TM questionnaire. CLUE is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response. 97% of the scores fall within 0 and 120 (mean +/-3XSD).
8 -12 days post wear
Distance Binocular Visual Acuity (LogMAR)
Tidsram: 8- 12 Days post wear
Distance time controlled LogMAR Visual Acuity was carried out binocularly with high luminance and high contrast.
8- 12 Days post wear
Intermediate Binocular Visual Acuity (LogMAR)
Tidsram: 8-12 days post wear
Intermediate time controlled LogMAR Visual Acuity was carried out binocularly using High lumiance and High Contrast.
8-12 days post wear
Near Binocular Visual Acuity (LogMAR)
Tidsram: 8-12 days post wear
Near time controlled LogMAR Visual Acuity was carried out binocularly using High lumiance and High Contrast.
8-12 days post wear
Corneal Staining
Tidsram: 8 - 12 Days post wear
Corneal staining is evaluated using Sodium Fluorescein strips. The Fluorescien strip was lightly placed on the subject's inferior palpebral conjunctiva. The corneal Staining was graded using the scale Grade 0: No Staining, Grade 1: Trace(Minimal superficial staining or stippling), Grade 2: Mild (Regional or diffuse punctate staining), Grade 3:Moderate(Significant dense coalesced staining, corneal abrasion or foreign body tracks.), Grade 4 Severe(Severe abrasions greater than 2 mm in diameter, ulcerations, epithelial loss, or full thickness abrasion.). The data was dichotomized into two group subjects with grade 3 or higher staining, and those subjects with less than Grade 3. Below the percentage of subject eyes with grade 3 or higher is reported for each lens.
8 - 12 Days post wear
Bulbar Conjunctival Injection
Tidsram: 8- 12 Days post wear
The bulbar is the scelra. Bulbar Conjunctival Injection was assessed using an Efron Grading scale by 1 unit increments. Grade 0: Normal, Grade 1: Trace, Grade 2: Mild, Grade 3: Moderate, Grade 4:Severe. The data was dichotomized into two group subjects with grade 3 or higher Conjunctival injection, and those subjects with less than Grade 3. Below the percentage of subject eyes with grade 3 or higher is reported for each lens.
8- 12 Days post wear
Limbal Conjunctival Injection
Tidsram: 8- 12 Days post wear
The Limbus is the 1 to 2mm wide zone of conjunctiva and underlying tissue adjacent to where the cornea joins the sclera. Limbal Conjunctival Injection was assesed using the Efron grading scale in 1 unit increments. Grade 0: Normal, Grade 1: Trace, Grade 2: Mild, Grade 3: Moderate, Grade 4:Severe. The data was dichotomized into two group subjects with grade 3 or higher Conjunctival injection, and those subjects with less than Grade 3. Below the percentage of subject eyes with grade 3 or higher is reported for each lens.
8- 12 Days post wear
Contact Lens Fitting
Tidsram: 8- 12 Days post wear
Contact Lens fitting is reported as a binary response. Yes- acceptable lens fit, No- unacceptable lens fit. The percentage of subject eyes with acceptable fit is reported.
8- 12 Days post wear
