Since 1 August 2008 the provision of General Ophthalmic Services in England has been subject to contracts between Primary Care Trusts and those providers (whether professionally qualified or lay) who have met certain criteria regarding premises, equipment, good character and so on (as under the old Terms of Service as amended). (GOS sight tests are performed by optometrists and OMPs, who must be listed as performers by PCTs.) Contracts can be for ‘mandatory services’ (ie. testing in a practice) or for ‘additional services’ (domiciliary testing). Model contracts are available below as PDFs. They are also obtainable from the NHS Primary Care Contracting website. Click here to view the NHS PCC website.
