Diabetes eye testing

For the last few years I have had my regular diabetes. I check at the mobile unit parked outside from Fieldhouse surgery. This is extremely convenient to me particularly as they can be a difficulty in returning to clear vision after the drops have been put in. The last invitation for a test told me to go to Wycombe market and part of the text said that my eyes might not return to normal vision for up to 6 hours. Does this mean that I have to stay in this small town for that period of time or ask someone to take me and bring me back. That assumes that there is such a person I can:. I can call on. Can you please explain why the mobile facility has been dropped. This is certainly a community service which has worked well for me in the past.
