A MS Excel file has been prepared with all data fields necessary for IOL constants optimization. This file is available in German or in English.
In this spreadsheet file, the data fields shown below
must be filled in for each IOL type in question and as many patients (n>50)
as possible with axial lengths out of a range as broad as possible
(e.g. 18 mm < axial length < 29 mm). Exclude cases with complications during
surgery, capsular ruptures etc, sulcus fixation, aphakic and pseudophakic
eyes, eyes with silicone oil tamponade, eyes after refractive surgery etc.
BCDVA should be 10/20 and/or better. Refraction should be stable
(3 months postop, refraction is considered to be stable).
For optimization of lens constants for the IOLMaster, it is necessary
that all fields contain reliable data.
The spreadsheet with clinical data should be handed over to a Carl Zeiss Meditec
representative or sent as attachment via e-mail
directly to
wh@ocucalc.de .
