• The measured results of patients with asteroid hyalosis may not be
accurate (in particular the axial length measurement) and must
therefore be verified by the user in terms of their plausibility.
1.8 IOL calculation
The measurements taken with the Eyestar 900 may serve as the central element for
the calculation of intraocular lenses (IOL). A further important parameter in
calculating the lens to be implanted is the IOL constant. When using the Eyestar
900, only IOL constants optimised for optical biometers should be used. Please
contact your IOL manufacturer for information on optimised IOL constants for optical
biometry. An alternative source of information for IOL constants optimised for optical
biometry is the website of the 'User Group for Laser Interference Biometry' (ULIB)
(
http://ocusoft.de/ulib/c1.htm
). Downloadable IOL Constants files for the Eyestar
900, featuring the ULIB IOL-Constants for the formulas implemented in EyeSuite
IOL are available in the Key-User section of the Haag-Streit homepage.
To further improve the clinical result, Haag-Streit recommends that every surgeon
creates personally optimised IOL constants based on pre-operative measurement
data generated with the Eyestar 900 and reliable postoperative data (e.g., 3 months
after the operation).
