Diagnostic Tests

All diagnostic tests are performed by dedicated ophthalmic technicians.

The results are normally available for collection shortly after the test has been carried out.

Alternatively, we can send the results by email or post to the referring specialist. All imaging results are printed on photographic quality gloss paper.
