Conditions
Brief summary
To cross-validate two new peripheral aberrometers: the EyeMapper and the Hartmann-Shack (HS) Scanner with dilated and undilated pupils.
Interventions
Participants will be required to attend one visit. For the EyeMapper instrument, the participant’s head will be positioned on a chin rest and look at an internal fixation target. No contact will be made with the eye at any time. Following alignment, measurement is taken. Five consecutive measurements will be performed per instrument. Overall duration of measurements will be 10 minutes

Exclusion criteria
Any pre-existing ocular irritation, injury or condition (including infection or disease) of the cornea, conjunctiva or eyelids that would preclude contact lens fitting and safe wearing of contact lenses. Any systemic disease that adversely affects ocular health e.g. diabetes, Graves disease, and auto immune diseases such as ankylosing spondylitis, multiple sclerosis, Sjogrens syndrome and systemic lupus erythematosus. 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 clinical trial. 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 clinical trial. NB: Systemic antihistamines are allowed on an “as needed basis”, provided they are not used prophylactically during the trial and at least 24 hours before the clinical trial product is used. Eye surgery within 12 weeks immediately prior to enrolment for this trial. Previous corneal refractive surgery. Rigid gas permeable or orthokeratology lens wear in the past month. Known allergy or intolerance to ingredients in any of the clinical trial products. Currently enrolled in another clinical trial.
