On completing his specialist training and after graduating with first class honours, he travelled to the UK for sub-specialist training in Cornea and Anterior Segment at the world-renowned Moorfields Eye Hospital - NHS Trust between 2004 and 2006. This enriching experience led him to continue clinical assessments and research work in the UK, by continued sub specialist training in Medical Retina and Uveitis at Moorfields for further two years. In his additional two years at Moorfields, he published seminal articles in peer reviewed journals, including the MUST trial for Uveitis and - often-cited - clinical trial for the use of methotrexate in inflammatory eye disease. Dr Pacheco was offered a post at Moorfields as a Specialist Doctor in Ophthalmology, where he continued to practice until 2012. During this time, he was a pioneer in the use of anti-VEGF therapy for treating wet AMD, running the very first intravitreal suit clinics, and he worked tirelessly at the A&E department, serving the community. Highly trained and regarded by his patients and colleagues, Dr Pacheco continues to practice ophthalmology at a primary care level, serving local populations at NHS community services as part of Operose Health until present days.
