Details
The Contact A-Scan Biometer uses high-frequency ultrasound to measure the axial length of the eye. It is particularly useful for patients with dense or mature cataracts, where optical biometry using laser technology cannot obtain accurate measurements due to poor light penetration.
Diagnose/Check
Calculates the appropriate intraocular lens (IOL) power prior to cataract surgery.
