In market taxonomy for Ophthalmic Ultrasound Equipment, the types segment is divided into A-scan and B-scan technologies. A-scan ultrasound, which measures anterior chamber depth and intraocular lens power, constitutes ~60% of the market, driven by its critical role in intraocular lens implantation. B-scan ultrasound, used for posterior segment imaging (e.g., retinal detachment, vitreous hemorrhage), holds ~40% market share, with demand fueled by its non-invasive imaging capabilities for complex ocular pathologies. The A-scan segment benefits from standardization in cataract management protocols, while B-scan devices see growth in trauma centers and retinal specialty clinics. Technological advancements in B-scan, such as 3D imaging and Doppler functionality, are narrowing the revenue gap, reflecting evolving clinical priorities toward comprehensive diagnostic solutions.
