Understanding this equipment family

Optical biometry is the shared function of the references in this selection. When preparing a measurement station, distinguish biometric measurements from keratometry or topography where these are documented for a model: these measurement sets are not interchangeable.

Questions to clarify before choosing

  • Which measurements are documented for your protocol and selected model?
  • Does the compared figure describe a range, resolution or repeatability under defined conditions?
  • Which modules, software and accessories are explicitly listed in the proposed configuration?

Configuration and documentary limits

Repeatability measured in a manufacturer study does not guarantee individual accuracy. Options and software versions must be checked against the instructions for the relevant configuration.

Documented differences between models

All three references document optical biometry and keratometry; corneal topography also appears in the HBM-1 record. This difference in recorded evidence does not establish that another model lacks a function. For Lenstar 900, T-Cone is optional and Cornea map depends on software.

The functions below are attached to a specific model and source. A function absent from this record is not declared unavailable: it remains unconfirmed here. Options and qualifications in the product records retain their meaning.

  • Brochure 1511.7220032.02120, 13th edition 2025-02, table on page 11; instructions 1500.7220055-04150, 2022-09, pages 16–18. The measurement ranges in the instructions are based on Phakic mode. In vivo repeatability is stated at 1 sigma according to the manufacturer’s study; resolution must not be confused with guaranteed individual accuracy. Standard weight 6.2 kg is distinct from APS 6.6 kg; the secondary power supplies also differ. T-Cone is optional; Cornea map depends on the software version. Native official photograph, 1270 × 1270, with an illustrative monitor not stated to be included. Identity, historical images and VERSUS profile preserved.
