IOLA 4C

Easily Measure Any Refractive Lens

Introducing the IOLA 4C lens analyzer (Replacing the IOLA Plus)

The Rotlex IntraOcular Lens Analyzer - IOLA 4C – is a powerful wave front analyzer designed for comprehensive inspection and analysis of intraocular lenses. It measures within 4 seconds all types of refractive IOLs whether dry or immersed in saline (or water).

The system utilizes our well known Moire Deflectometry, a unique technology, which enables objective, accurate and repeatable full aperture power mapping of IOLs and other lenses.

Measured type of lenses:

Spheric, toric, aspheric, (refractive) multifocal, toric, annular, non symmetric segmented, and more.

Measured quantities:

Power, cylinder, axis, addition (in MF and BF designs), MTF, quality, aberrations.

Output:

Power and Cyl maps in bmp, jpg, ASCII, and binary formats, radial profiles, cross-sections, power histograms, meridian power maps (for toric lenses), customized user-defined reports.

All these can be reproduced at any later time from lens files.

Interface:

  • The IOLA 4C is completely computerized
  • Data recording and sending through multi-option flexible communication mechanism. Objective acceptance/rejection criteria
  • Detailed customized measurement reports
  • Lens files which enable presenting data in all formats, for later reference.
  • Dual operation – Operator with a reduced set of operations, and Supervisor with full access to all functions.

Mechanics and power:

  • Dimensions: 28cmX17cmX50cm
  • No precision moving parts – means stable calibration and no maintenance
  • Long lifetime light source
  • 12VDC power supply
  • Runs on an external Windows PC
