Fix IOP according to corneal thickness

Here you have the IOP correction table used for adjusting intraocular pressure based on central corneal thickness (CCT). In order to fix IOP, just apply the correction factor on the right column to the intraocular pressure obtained by aplanation tonometry. Then you’ll have the adjusted IOP.

This pachymetry conversion chart is also available in our android app: CataracTools

Adjust intraocular pressure by corneal pachymetry

Several pachymetry measuring methods are available, just remember to use the complete value, including the epitelium and endotelium. In case of imprecise measurements, repeat 3 times and use the average value.
