Digital Computerised Perimetry

Ultrasonography
A‑B scanning for ocular evaluation and disease diagnosis.
A‑scan: measures anterior‑chamber depth, lens and ocular‑coat thickness, and axial length; performs IOL power calculation according to international formulas.
B‑scan: two‑dimensional imaging for vitreous assessment, documentation of retinal and choroidal detachment extent, detection and localisation of ocular and retro‑bulbar tumours, and foreign bodies.
Equipment: Alcon Ultrascan/Ultrasonik (USA‑Switzerland); Compact Touch Quantel Medical (France) – A‑B ultrasound scanner and pachymeter.

A/B ultrasound scanner, pachymeter Compact Touch, Quantel Medical
Provides a wide measurement range and easy data import. Applications – pachymetry, biometric measurements, A/B scanning (sectoral ultrasound with 2D image creation).

Computerised Topography and Ultrasonic Pachymetry
Accurate measurements prior to refractive surgery.
SIRIUS CSO, Italy – Before undergoing vision correction surgery, all patients undergo an ultrasound-based corneal thickness measurement. This method makes it possible to calculate the maximum permissible depth of treatment, which—depending on whether the case involves myopia, astigmatism, or hyperopia—determines how fully and safely the correction can be performed. The ultrasound device measures corneal thickness at 17 distinct points with an accuracy of up to 1 micron.
Ultrasonic corneal‑thickness measurement at 17 points with 1 μm resolution.
Pachymeter programmable to the physician’s parameters: measurement sequence, speed of sound (1000–2000 m/s), offset factor shape and value.
Probe: 20 MHz; tip diameter 1.2 mm; 45° angle.
Results stored in device memory and printable.
Equipment: SIRIUS CSO (Italy).
