'Keratometry corrected' refers to a cornea where the front surface data are provided and the respective back surface data are calculated based on data of a schematic model eye. The corneal back surface astigmatism is statistically corrected with an astigmatism vector superposition, which could correct the centroid in a large population but not the individual back surface astigmatism.
'Front/back surface' can be used if data for the corneal front surface curvature and the corneal back surface curvature are available, e.g. from an anterior segment tomographer. The corneal front and back surface could have crossed cylinders, the axes are not necessarily aligned.
'Total power' refers to a thin lens model of the cornea. This calculation option is used if composit data are available from any anterior segment tomographer which represents the cornea as a thick lens. This data should be independent from the keratometer index. For TK data from the IOLMaster 700 please use the option 'Keratometry' as the data are bound to a keratometer index.">

Terms & conditions for LPCM


PLEASE NOTE OUR TERMS AND CONDITIONS FOR USE OF THE LENS POWER CALCULATION
MODULE

Our online calculator, based on the Castrop formula, assists ophthalmic surgeons
in selecting the individual IOL power in cataract surgery. It is intended to be
used in conjunction with a comprehensive ophthalmic examination and the
appropriate diagnostic tests and measurements required for candidates for
cataract surgery. The results obtained with the calculator are not intended as
medical or surgical guidance and cannot be considered definitive, nor can the
results be guaranteed to be accurate in every case. Physicians using the
calculator must make their own independent decisions about the correct treatment
for their patients and are solely responsible for the outcome of the refraction.
Furthermore, the information about our Castrop formula IOL calculator, available
on this website, is provided without warranty of any kind, either explicit or
implicit. Our online calculator is subject to copyright and other intellectual
property rights under German and foreign laws and international conventions. It
may not be copied, imitated, or used, in whole or in part, without the prior
written permission of Prof. Dr. Achim Langenbucher and Dr. Peter Hoffmann.
