Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Test group will be randomised to instil Moxifloxacin antibiotic drops twice a day into each eye on waking and prior to sleep (in the evening). Commercially available siliconhydrogel lenses are to be worn on a continuous wear basis (that is, during the day and night) for approximately I month
Intervention code [1] 257354 0
Prevention
Comparator / control treatment
Control group will instil unit dose saline (5mL, 0.9% sodium chloride)lubricant as treatment twice a day into each eye on waking and prior to sleep (in the evening). Lenses are to be worn on a continuous wear basis (that is, during the day and night) for approximately I month
Control group
Active

Outcomes
Primary outcome [1] 259366 0
Reduction of contact lens related inflammatory ocular adverse events compared to control group. Ocular redness (bulbar limbal and palpebral), palpebral roughness and corneal and conjunctival staining will be assessed and recorded using the Brien Holden Vision Institute Grading scales. History (including medical and general health) at baseline, and changes from baseline history that occur between visits, will be recorded in the source documentation at each visit.
Timepoint [1] 259366 0
Ocular examination using slit-lamp biomicroscopy will be carried out at baseline and all follow up visits (i.e. 1 night, 1 week (if a neophyte- new contact lens wearer) and 1 Month)

Undergone previous corneal refractive surgery,
Contraindications to contact lens wear,
Allergy or intolerance to moxifloxacin or other quinolones/fluoroquinolones,

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be pre-screened for suitability by way of a routine eye examination which includes refraction, visual acuity and general eye health. Informed consent will be obtained prior to any clinical trial procedures. Participants will be randomly allocated into either the lubricant or antibiotic drop instillation group. Concealed allocation will be by way of central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned to either the saline or antibiotic drop grou. A randomisation plan will be generated from http://www.randomization.com/. The randomisation list will be generated based on an independent group design
Masking / blinding
