Visual performance of early presbyopes fitted with contact lenses

INTERVENTION: Up to 30 potential participants will attend the research clinic for the first visit (screening / enrolment / test familiarisation visit) to initially obtain their informed consent and screen them for their suitability to take part in the investigation. They will be asked to attend the clinic wearing their spectacles, the potential participants will not have worn their contact lenses prior to the visit the day of the visit. After informed consent has been given, the investigator will review the participant’s medical history, ocular history (including concomitant treatments), demographics and contact lens wear history. A series of routine optometric assessments and tests will be conducted to determine the participant’s prescription and evaluate the participant’s ocular health. Once it has been verified that the participants meet the inclusion/exclusion criteria they will be considered as enrolled, and they will be fitted with the control contact lenses and familiarize with the study tests. At the conclusion of the visit the participants will be scheduled to attend the study test visit. The participants will return for the second visit (test visit) wearing their spectacles and will not have worn their contact lenses prior to the visit the day of the visit. Their concomitant medications will once again be reviewed. The test or control contact lens (randomised) will be inserted and worn for 15 minutes. 15 minutes later a set of visual performance tests and vision quality questionnaires will be carried out. The order 1 study contact lens will be removed, and the second contact lens will be inserted, and the same routine will be repeated. At the end of the study contact lens order 2 will be removed and safety ocular integrity evaluation will be carried before discharge from the study.
