CARL ZEISS IOL Master v3 A-Scan
The IOLMaster is to be used only for the measurement of axial length, corneal curvature, anterior chamber depth and optionally for "white-to-white" determinations of the human eye, as well as for the calculation of the required intraocular lens.
The IOLMaster is a combined biometry instrument which measures parameters of the human eye needed for intraocular lens calculation. It measures quickly and precisely the following eye parameters:
• Axial Length (distance between tear film and retina)
• Corneal curvature
• Anterior chamber depth
• "white-to-white" (optional)
All measurement are non-contact measurements providing excellent patient comfort.
The axial length measurement is based on a patented interference optical method known as Partial Coherence Interferometry (PCI). The displayed results of the axial length measurements are comparable to ultrasonic immersion measurements of axial length via the use of an internal, statistically verified calculation algorithm.
The corneal curvature is determined by measuring the distance between reflected light images as in conventional keratometry.
The anterior chamber depth is determined as the distance between the optical sections of the crystalline lens and the cornea produced by lateral slit illumination.
"white-to-white" is determined from the image of the iris.
Biometric eye measurements with the IOLMaster can be learned very quickly without time consuming training courses.
Extensive integrated safety features ensure both the patient and operator maximum safety when using the IOLMaster.
The software of the IOLMaster runs under Windows. The LCD display functions both in patient eye alignment as well as a results and calculating interface. The instrument is controlled via the joystick and computer keyboard with integrated touchpad (mouse).
The integrated computer calculates the optimal intraocular lens on the basis of the measured values and international calculation formulas. Five formulas are integrated as standard.
Prior to use the data of the desired lenses must be entered into the database.
On the basis of postoperative refraction results, the lens constants that are entered in the calculation formulas may be individually optimized (personalized) for every user. In doing this, the data records of patients who had refractive surgery of the cornea should be ruled out.
The computer of the IOLMaster operates on the Windows operating system. For safety reasons, the operating system is not accessible to the user.
The known operating conventions of Windows analogously apply to the user interface of the IOLMaster software. This refers to the use of mouse/touchpad, the operation of buttons, the work with dialog boxes and menus, confirmation by double-click, etc.
