They received a call from Dora to conduct a follow-up assessment three weeks after their operation.Dr Kanmin Xue, honorary consultant ophthalmologist and co-principal investigator at Oxford University Hospitals NHS Trust, said: "The Dora system is able to call patients autonomously by telephone and conduct a conversation that gathers the key information needed to determine whether a patient is recovering well or requires further medical assessment. "It was successful in identifying and prioritising those individuals who needed additional clinical input."Cataract surgery remains the most frequently performed surgical procedure in the UK, with almost half a million operations performed every year, according to the Royal College of Ophthalmologists.The routine procedure to treat blurry vision involves replacing the eye’s natural lens with an artificial one.Dr Xue said the volume of patients requiring the treatment meant it was not always possible to provide a follow-up appointment with a clinician but that using Dora had significantly freed up staff's time.He said over the past year, Dora had made more than 12,000 calls to patients in the South, each lasting about eight minutes."If you think about it, it's like having two nurses calling all day and doing nothing else," he said."That is a substantial amount of time they can now invest in delivering face-to-face care in other clinical activities."Frimley Health NHS Trust introduced the Dora system in December 2022 and estimates it has freed up more than 530 hours of nursing time.The trust carries out 5,000 procedures a year and a backlog created by the covid pandemic meant patient call times had slipped from within two weeks to 10 weeks. A month after launching Dora, the surgery-to-call time had fallen from 10 to two weeks, with the backlog of calls cleared, it said.<figure><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=2nmK1p_0uopbBS400" alt="https://img.particlenews.com/image.php?url=2nmK1p_0uopbBS400" width="976" height="549" ><figcaption>Image caption, Ron Hart is having cataracts in both eyes removed</figcaption></figure>Ron Hart, 73, from Bicester, Oxfordshire, had the cataract in his right eye removed at Cherwell Hospital, in Banbury.

AI assistant eases NHS pressure in cataract care
