Primary Outcome Measures :
  1. Cost-analysis: Healthcare resource use attributable to managing patients in this study will be collected. [ Time Frame: up to 2 months ]
    These include (but not necessarily be limited to) the cost of surgery for both arms of the trial (including resource use and staffing levels required for the surgical protocols), resource use attributable to managing complications arising from surgery, all relevant diagnostic investigations, further surgery where necessary, hospital length of stay and ward type, outpatient attendances, procedures performed on an outpatient basis, Accident & Emergency attendances and prescribed drug medications. The quantity of resource use for each cost component will be measured from medical records. Site-specific unit costs will be taken in preference of standard published sources or national tariffs where possible.

  • Patients must have reduced visual acuity or visual symptoms attributed to the presence of cataract in one or both eyes by the examining ophthalmologist or else must require cataract surgery on clinical grounds other than visual symptoms.
  • Patients must be willing to attend for follow-up at 1 month after cataract surgery.
  • Patients must be sufficiently fluent in English for informed consent and self-completion of the patient reported outcome questionnaires.

Exclusion Criteria:
