The use of the pachymeter measures the entire thickness of the cornea, the thickness of the flap and then with an understanding of the amount of tissue removed during the treatment it is possible to calculate the amount of cornea left at the bottom. In general, it is best to leave about 300 microns of tissue...

Pachymetry is the measurement of corneal thickness
Pachymetry is the measurement of corneal thickness. Corneas that are too thin or thick due to pathology (disease) are not likely to be able to have laser vision correction. Visian (phakic intraocular lens implants) may be considered if corneas are too thin for laser treatments.

If a patients cornea is too thin for LASIK or PRK it does not mean their cornea is 'abnormal", however, it may mean they are a better candidate for a Phakic IOL procedure(also known as an implantable contact lens). The decision as to which is the...
