How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Use of Corrective Visual Aids (i.e., Spectacles, Contact Lenses) Post Intraocular Lens (IOL) Surgery (time frame: Baseline and 1 week). It is what the study was designed to measure, not a finding.
