service models
Service models
  • “Traditional” hospital optometry low vision clinic
  • “One stop shop” e.g. Birmingham Focus, RNIB Judd Street, Gateshead
  • Community model e.g. Welsh Low Vision Scheme
    • Main advantage is ease of access
    • More challenging cases difficult to manage
    • Initial set-up and accreditation
  • To date no reliable research to compare outcomes or cost-effectiveness with different models

  • Number of LVC appointments risen from 2500 to 5000 in last 10 years
