Very professional. Good ’bedside’ manner. Explained clearly. Only issue was delay in letter to GP which caused me to run out of drops as GP didn’t have a request for a repeat prescription in time after the drops I’d obtained on a private prescription provided by the consultant ran out.

Siene was an extremely pleasant and thorough consultant at the spire hospital Cardiff . During every visit to her clinic she explained very descriptively how my glaucoma was being controlled and all her tests were thorough. Overall , we were very pleased with the experience and , following on , I am now being monitored every 6 weeks via the local NHS Many thanks for the attention you’ve given Mr. Bryan J

I have had cataract done in both eyes. The procedure was a very relaxed extremely professional process. I am cheaply with the results. I would recommend me siene ng to anyone I know that is looking to have the same procedure done. The staff were also amazing.

Everything fine. Doctor explained the results of the procedure and today's test. Great results and I would definitely recommend Nuffield Health Care to others.
