As you may be aware, Operose took the decision to cease providing all ophthalmology services locally and nationally in March 2023. All Operose patients have been transferred to the new provider, Buckinghamshire Healthcare NHS Trust (BHT).

NHS BOB ( Buckinghamshire, Oxfordshire, Berkshire West ) ICB have been working with BHT and colleagues from the LOC to support safe transfer of service. In the meantime, waiting times for routine community services may  increase but this will be a temporary position until the new service is in place and stabilised.

Please continue to refer as per your existing routes – EeRS/Rego for routine referrals &  NHSmail for EyeCasualty, WetAMD and Direct Cataract.

For more detailed local information on referral pathways in Mid & South Bucks, please download the March 2024 version of Eyecare Pathways Mid & South Bucks which should be displayed in every consulting room. Please also refer regularly to other information on this page, and look out for email updates.


Direct cataract referral scheme

Cataract referral for any patient with a GP in the Buckinghamshire ICS area should only be made on the Direct Cataract Referral Form (available in Word or pdf) by an optometrist accredited to do so. Optometrists not accredited should refer to an accredited colleague. For information on how to gain accreditation, download this document. Please refer also to the most recent cataract referrals threshold document, issued by Bucks CCG in October 2011, but reviewed and approved by BHT in 2019.

Waiting time for Stoke Mandeville (at Jan 2024) is currently 8-10 weeks from referral to surgery. Most cataract operations now take place in the standalone cataract theatre. Watch a virtual tour of the cataract theatre and the patient journey.  Toric IOLS and /or immediate sequential bilateral cataract surgery (ISBCS) is offered to those patients who are deemed as suitable.

Direct cataract referral forms may now be emailed to Stoke Mandeville Hospital: (only from an account).

Invoices for direct cataract referrals must be sent to NHS SBS via email to  A template invoice is available for download. NHS SBS requests that you adhere to good invoicing practice. Please note that invoices should not contain any information which could identify the patient (eg NHS number) but should include the GP practice code, which usually begins with the letter K (eg for Amersham Health Centre it is K82004). A list of CCG GP member practices with their practice codes is also available for download. Invoices should be sent on a monthly basis, and not saved up to be sent in batches. NHS SBS customer service centre may be contacted on 0303 123 1177.   Queries about invoices may be sent to Linda Page   -please attach a copy of the invoice.


Referring cataracts to other providers

By default, patients will have their surgery performed at Stoke Mandeville (although pre-op clinics are also held at Wycombe). Patients may exercise their right of choice, and be seen outside the area. The NHS website has a search tool which can provide current waiting times for local service providers.

Bucks CCG has confirmed (October 2020) that you may send the direct cataract referral (DCR) form to an alternative NHS provider and invoice Bucks CCG in the usual way. However, for the fee to be paid, the alternative provider must accept direct (one-stop) cataract referrals. Most NHS hospitals will do this, but some clinics do not, so no DCR fee will be paid in these circumstances. You are therefore advised to check this with the provider.


Cataract Post-op Portal 

As of June 2024, patients attending for cataract surgery at BHT will be given a printed letter to take their optometrist when attending the post-op refraction appointment. The letter will have their unique PIN code and a link to the secure Medisight Portal. This is to enable BHT to collect post-op visual acuity and refractive outcome data. A fee of £10 per return will be paid by the ICB. Invoices should be emailed to NHS SBS at ,following the same procedures as for the Direct Cataract referral invoices. An updated template invoice is available to download.

Please note: This portal is NOT for referring patients. It is purely for collection of cataract post-op data. All referrals should be sent using appropriate existing referral pathways.

For further details see the letter from Buckinghamshire NHS Trust here.



Following NICE guideline NG81 (November 2017) ophthalmologists working in Buckinghamshire Healthcare NHS Trust agreed that patients should now be referred to BHT on IOP >= 24 mm Hg (instead of the previous threshold of >21 mm Hg), in the absence of any other signs.

The Bucks IOP repeat readings scheme ceased in October 2020. The view of LOCSU is that optometrists working in areas where no repeat measures scheme is in place should not be criticised for false positive referrals which are the result of a lack of commissioning.


Urgent & Emergency Referrals

The hospitals have asked us to remind you not to quote to patients the timescale in which they will be seen. This decision needs to be made by the doctor who is triaging the case, and worried patients can often get quite upset if the appointment time given to them doesn’t match their expectations.

A new document on  Referral Information for Stoke Mandeville Eye Casualty was produced in March  2022. Urgent referrals should be sent via Rego, clearly marking it as Urgent by selecting the urgent option.  Emergency referrals should be referred by email to Please use the associated SMH eye casualty referral form.

Please note: Eye Casualty at Stoke Mandeville is NOT a walk-in service.

They are not staffed to provide a Walk-in Service and can only offer booked urgent appointments 7 days a week.


Wet AMD referrals

For suspect wet AMD referrals, please download the rapid access referral form and email it to   or send via Rego using the Wet AMD option. An acknowledgement  email will be sent to the referrer upon receipt of the referral.



Private ophthalmology at Stoke Mandeville Hospital

Buckinghamshire Healthcare NHS Trust now offers private ophthalmology care at its Mandeville Wing, running evening outpatient clinics on Monday evenings, and operations on Saturdays. Download an information leaflet here. For enquires, you can call the Private Patient’s Office number :01296 315131


The information on referral pathways is intended to be helpful rather than definitive, and there may be a delay in updating information when pathways change. For urgent or emergency referrals we recommend practitioners confirm the provider has received the referral and/or give clear advice to patients on what action to take if they have not been contacted within an appropriate time frame.
