摘要:
Described herein are devices and methods that dampen transient intraocular pressure including pressure spikes experienced by the eye. The illustrative embodiments attenuate pressure waves and, thus, reduce wall stresses in a non-compliant eye such that the optic nerve is protected from damage in an ocular hypertensive or glaucoma patient, or during traumatic ocular procedures, and the refractive disorders of myopia, hyperopia, and/or presbyopia are moderated or reversed. In one embodiment, a compressible attenuation device insertable within the chambers of the eye preferably has an expanded volume within the range of from about.01 cc to 7 cc. The attenuation device may include a valve for filling the attenuation device and a high vapor pressure media having a vapor pressure approximately equal to the intraocular pressure of the eye and a permeability of less than 1 ml/day at body temperature through an outer wall of the device.
