Biomicroscopy provides visualization of both the anterior part of the eye and deeper structures by placing a special lens in front of the eye. To thoroughly examine the retina, the eye doctor will apply eye drops before the examination to dilate the pupil, causing blurry vision for 3-4 hours, particularly affecting near vision.
Therefore, you should not drive to the eye doctor and plan the visit so that the blurry vision does not interfere with the rest of your day. It is also worth noting that using eye makeup before the visit is not recommended, or you should be prepared to reapply it afterward.
Both services covered by the National Health Service (NHS) and insurance companies, as well as paid services, are available.
