BIOMICROSCOPY

A complete biomicroscopic examination is required prior to contact lens fitting.  One must rule out any ocular disease that might contra-indicate contact lens fitting,  detect any conditions indicating a certain type of lens, and record any abnormalities present prior to fitting so one knows if contact lens wear has caused changes.

The biomicroscopic examination should include an examination of:

- the lids and lid margins
- bulbar conjunctiva
- tear film
- inferior palpebral conjunctiva
- eversion of the upper lid to examine 
        superior palpebral conjunctiva
- limbal area
- cornea
- anterior chamber angle
- iris and crystalline lens

See the module on the biomicroscope  for a 
detailed prefitting biomicroscopy examination.
