Abstract

Corneal Hysteresis is emerging as an important tool in management of many ocular conditions like corneal ectasia, refractive surgery screening but the data available till now is lacking to provide a conclusive guideline regarding the normative database. This review suggests that corneal hysteresis can be utilized as a marker of many ocular pathologies and its diagnostic and prognostic capacity needs to be explored further. The application of corneal hysteresis in glaucoma is just the tip of iceberg of its clinical utilities. The most significant application of corneal hysteresis in recent years is in the field of refractive surgery and corneal ectasia. In the latest software version of Ocular Response Analyzer (ORA) multiple specific parameters for keratoconus have been included – The keratoconus match probability (KMP) index - (KMP-KC normal, suspect, mild, moderate and severe) and keratoconus match index. The recent literatures have proven its efficacy in management of not only glaucoma but other pathologies also, but the normative values and dedicated markers are needed to be invented for different clinical conditions.
