Tomey OA-1000

The Tomey OA-1000 is an advanced A-Scan ultrasound biometer designed for fast, precise, and reproducible ocular measurements. Manufactured by Tomey Corporation (Japan) — a trusted global brand in ophthalmic instrumentation — this device provides dependable results for axial length, anterior chamber depth, lens thickness, and vitreous length measurements.

The Tomey OA-1000 A-Scan Optical Biometer is commonly used for:

  • Cataract surgery biometry and IOL power calculation
  • Pre- and post-operative refractive evaluation
  • Ocular growth monitoring in myopia and pediatric ophthalmology
  • Routine biometric screening in optical centers or hospitals

This unit allows accurate measurements even in dense cataracts or low visibility conditions where optical biometers like IOLMaster may fail — making it a practical and affordable choice for many eye-care professionals.
