Controlling blepharospasm effect during applanation tonometry using the Volk SuperField Lid Lens Adapter.
OBJECTIVE
To describe a practical clinical technique that can be used to control the effect of blepharospasm during applanation tonometry.


METHODS
The Volk Superfield NC Lid Lens Adapter is used to keep the eye open and prevent the squeezing effect of orbicularis oculi in blepharospasm.


RESULTS
This helpful tool can be used when blepharospasm becomes a problem that interferes with accurate intraocular pressure measurement.


CONCLUSIONS
The technique is potentially useful and relatively easy to perform.
