Corneal hysteresis test
WebNov 5, 2024 · Measuring corneal hysteresis, or CH, is the next evolutionary step in the process of understanding this. CH is much more than a measure of thickness—it’s a measure of the shock-absorbing capacity of the cornea, and hence, the shock-absorbing capacity of the eye. (A high level of hysteresis means the cornea has a large capacity … WebMay 13, 2016 · Corneal hysteresis can’t be paid the same day as CPT code 99211 Technician code, or the two HCPCS codes for glaucoma screening G0117 and G0118. …
