Recent recalls

• 2015-12-01TerminatedSoftware design

  IOL Master 5.5: Software versions 7.5 and 7.7; Ophthalmic: used to obtain ocular measurements and perform calculations to allow physicians to determine appropriate IOL power and type for implantation.

  IOL Master software versions 7.5 and 7.7 calculation printouts and exported reports can contain the wrong IOL power data.

• 2015-12-01TerminatedSoftware design

  IOL Master 500: Software versions 7.5 and 7.7; Ophthalmic: IOL Master 500 is intended for biometric determination of ocular measurements of axial length, anterior chamber depth, corneal radius, white-to white (WTW), and for the measurement of pupil size and deviation of the visual axis from the center of the pupil.

  IOL Master software versions 7.5 and 7.7 calculation printouts and exported reports can contain the wrong IOL power data.

• 2013-11-15TerminatedSoftware in the Use Environment

  Zeiss brand IOLMaster, Version 1-5, Biomicroscope, Slit-Lamp, AC-Powered, Product is manufactured by Carl Zeiss Meditec AG (Jena), Carl Zeiss Promenade 10, Jena, Germany 07745; and distributed by Carl Zeiss Meditec, Inc., Dublin, CA This device is intended for use primarily by physicians and health care workers and may be only used under the supervision of a physician. This device will not be sold to the general public. The IOLMaster is intended for the biometric determination of ocular measurements of axial length, anterior chamber depth, corneal radius, white-to white (WTW), and for the measurement of pupil size and deviation of the visual axis from the center of the pupil. For patients who are candidates for intraocular lens (IOL) implantation, the device also performs calculations to assist physicians in determining the appropriate IOL power and type for implantation

  The user database delivered for download contained an erroneous value. Specifically the "aO" constant of the lens AMO Sensar AR40E is listed as "0.0" in the internal lens database of the IOLMaster. The correct value is -2.420. This could lead to the implantation of lens with a wrong diopter value.

• TerminatedEmployee error

  Carl Zeiss Meditec AG, Goeschwitzer Strasse 51-52 07745 Jena, Germany, IOLMaster 700, REF 1932-169 SN 1185393 2017-09-01

  Calibration setting was incorrectly entered during manufacturing causing the optical coherence tomography (OCT) to obtain the incorrect two-dimensional images of ocular structures of the anterior and posterior segments of the eye.

• TerminatedSoftware in the Use Environment

  OPTICAL BIOMETER AL-Scan: Software Version: 1.09 and earlier. Ophthalmic: The OPTICAL BIOMETER AL-Scan is a measuring device that can measure as a single unit the values necessary to calculate the power of an IOL for cataract surgery such as axial length, corneal curvature radius, and anterior chamber depth. It measures these necessary values successively through a non-contact optical measurement method.

  Nidek Inc. received information from our manufacturer NIDEK CO. Japan that the shown axial lengths were much shorter at AL-Scan measurement.
