IOP correction table used for adjusting intraocular pressure based on central corneal thickness (CCT). In order to adjust the IOP, just apply the correction factor on the right column to the intraocular pressure obtained by aplanation tonometry. Then you’ll adjust the IOP.
This table is also available at our android app: CataracTools.
