Personally, I would continue to attend the appointment. My husband had his Cateract eye operation last Monday which got cancelled from the week that Lockdown began. The care and levels of hygiene throughoout the proceedure were fantastic, and hes now safely back home and delighted with the result. We were both shielding throughout the lockdown period due to his age (80), and my medical problems, but it has now given me enough confidence to speak to my Gp next week regarding a much needed knee replacement operation in my left knee.
