What is COS?

Abridged Referral Guide:

Please refer patients via ERS using the drop-down menu and choose “Moorfields SPA” and use the referral form found on DXS and also available here.

This referral form is for adults and children with non-urgent sight or life-threatening conditions.

Please make sure all sections are filled fully, with as much clinical detail as possible. Referrals without adequate information for safe triage may be rejected or cause delay in appointment booking for your patient.

Please attach any GOS18 or other supporting document with this form.

We will triage and contact the patient directly with an appointment/advice on alternative services.

Referrals will be triaged within one working day; appointment letters should be received by patients within a maximum of 4 weeks.

Important Notes for Urgent Referrals:
