Description of intervention(s) / exposure
This is a prospective, single group, daily wear (DW) study where 90 participants will wear NIGHT & DAY [Registered trade mark] lenses bilaterally on a daily wear (DW) basis in conjunction with OPT-FREE [Trade mark] RepleniSH [Trade mark] solution for 4 months. There will be a minimum of 5 scheduled visits: baseline, 1 month visit, 2 month visit, 3 month visit and 4 month visit. These visits will involve assessment of visual acuity and examination with a slit-lamp biomicroscope (a specialised microscope for viewing the eye). Lenses will be worn a minimum of 5 days per week, and 6 hours on the day lenses are worn.

Conditions such as systemic hypertension and arthritis do not automatically exclude prospective participants;
-Use of or a need for concurrent category S3 and above ocular medication at enrolment and/or during the study;
-Use of or a need for any systemic medication or topical medications which may alter normal ocular findings/are known to affect a participant’s ocular health/physiology or contact lens performance either in an adverse or beneficial manner at enrolment and/or during the study;
N.B.: Systemic antihistamines are allowed on an ‘as needed basis’, provided they are not used prophylactically during the trial and at least 24 hours before study product is used;
-Eye surgery within 12 weeks immediately prior to enrolment for this trial;
-Previous corneal refractive surgery;
-Contraindications to contact lens wear;
-Known allergy or intolerance to ingredients in any of the study products;
-Currently enrolled in another clinical trial.
-Pregnancy: Formal testing of pregnancy is not required. A participant’s verbal report is sufficient

-The Investigator may, at his/her discretion, exclude anyone who they believe may not be able to fulfil the study requirements, or if it is believed to be in the participant’s best interests.

Summary
Brief summary
This study will examine whether a correlation exists between contamination of contact lens cases with Stenotrophomonas maltophilia and CIEs, when contact lenses and worn on a daily wear basis. The hypothesis is case contamination with Stenotrophomonas maltophilia does not correlate with CIEs.
