An Ophthalmic Ultrasound Scanner with Pachymeter is a dual-function diagnostic device using sound waves to measure internal eye structures (A-scan for axial length, lens thickness for IOL calculation in cataract surgery) and corneal thickness (pachymetry for glaucoma/refractive surgery planning), providing crucial data for precise diagnosis and surgical planning in ophthalmology. It combines A-scan biometry with pachymetry, often featuring high-frequency probes and advanced algorithms for accurate, non-invasive assessments.
