WebAug 1, 2024 · Corneal hysteresis (CH) is a measure of the viscoelastic dampening property of the cornea and is postulated to be a surrogate for the viscoelastic dampening properties of the posterior sclera and lamina cribrosa through which the retinal ganglion cell axons pass as they exit the eye. おからの別名
Cataract surgery causes biomechanical alterations to the eye
WebCorneal biomechanical properties are crucial in refractive surgery to discover any corneal anomaly and to maintain good postoperative quality of vision. 6 Some aspects of the corneal biomechanical properties are investigated using the ocular response analyzer (ORA), which measures corneal hysteresis (CH) and corneal resistance factor (CRF). WebApr 6, 2024 · Purpose To investigate potential impact factors associated with corneal biomechanical properties in Chinese myopia and further to investigate quantifying corneal biomechanics in clinical work.
