Intraocular pressure and corneal thickness

Ophthalmologists should be aware that tonometry readings may substantially underestimate IOP in patients treated for the correction of myopia with corneal laser techniques. In such patients, a correction using CCT values can only give indications. A tonometer device that aims to correct for dynamic corneal properties may be optimal, and careful monitoring of visual field and/or OCT in such glaucoma patients or suspects is required even with apparently low IOP.
