Lasik and Glaucoma

Submitted by dave on Tue, 08/07/2007 - 11:26am

A new theory (still being researched and discussed) is that glaucoma causes a remodeling of the cornea that results in lower corneal hysteresis (CH). However, regardless of the causative mechanism, low  corneal hysteresis has been correlated with glaucoma progression in early research. I believe the research on that point is substantial enough to act on the information right now, even though more research is warranted. 

It is also known that Lasik causes low corneal hysteresis - that's why Lasik will give you a false intraocular pressure reading (unless your ophthalmologist uses a more modern tonometer such as the Pascal Dynamic Contour tonometer or the IOPcc reading from the Reichert Ocular Response Analyzer). The fact that Lasik causes low corneal hysteresis and that low CH is correlated with glaucoma progression should be enough reason for many gluacoma patients to avoid Lasik at this time.
