Ophthalmological Diagnosis Ultrasonic A/B Scanner MDLOD21S
High-performance 10 MHz ultrasonic A/B scanner for comprehensive anterior and posterior segment imaging. Delivers exceptional axial resolution of ≤0.2 mm with dual-mode capability for biometric measurements and structural assessment. Ideal for cataract surgery planning, IOL calculations, and diagnostic evaluation of opaque media.
Clinical overview
The MDLOD21S is a precision ultrasonic imaging system engineered for comprehensive ophthalmic diagnostics and biometric assessment. Operating at 10 MHz, it delivers exceptional spatial resolution with axial accuracy of ≤0.2 mm and lateral resolution of ≤0.4 mm, enabling detailed visualization of anterior chamber structures, lens morphology, and posterior segment pathology. The dual A/B mode architecture supports both qualitative imaging and quantitative biometry, making it indispensable for cataract surgery planning, IOL power calculations, and evaluation of dense cataracts or corneal opacities where optical imaging is limited.
The mechanical sector scan method with 53° coverage and adjustable gain control (0–98 dB) ensures optimal image quality across diverse tissue densities and pathologies. Electronic calipers provide real-time distance measurement with ≤0.25 mm accuracy, while A Mode biometry achieves ≤0.06 mm precision for axial length and anterior chamber depth. Support for six IOL calculation formulas (SRK-1, SRK/T, SRK-II, BINK/2, HOLLADAY, HOFFER-Q) streamlines refractive planning workflows.
