Evaluation of the Eyhance and Zoe Lenses

The goal of this observational study is to assess distance and near visual acuity of patients who have undergone cataract surgery with two intraocular lenses (IOLs). The main outcomes are: To assess distance and near visual acuity of patients who have undergone cataract surgery with two intraocular lenses (IOLs) To assess depth of focus of the IOLs To assess tilt and decentration of the IOLs The potential participants will be chosen from the list of patients in the Southend NHS database who have had routine cataract surgery using the Zoe or Eyhance lenses in the past 12 months and contacted by phone and letter. The member of the ophthalmological team carrying out the screening will use the research inclusion and exclusion criteria to identify 50 potential participants. Once identified, the potential participants will be asked if they would be willing to discuss inclusion into the study with a member of the clinical care team (Prof Myerscough or Dr Law). If they agree, they will be asked to attend one further clinical visit. They will be given a patient information sheet and consent form at this visit. All potential participants will be informed that participation in this research study will be entirely voluntary. At the clinical visit participants will have their vision assessed, have dilating drops instilled, and undergo two non-invasive scans of their eyes.
