PURPOSE: 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.
