Description
Technical field
The present invention relates to medical instruments field, particularly a kind of intraocular pressure monitor and system for monitoring intraocular pressure.
Background technology
The cataractous sickness rate of China remains high, and cataract belongs to relatively blind.In recent years, usually utilize ultrasonic emulsification for cataract and intraocular lens implants to treat this disease, wherein the technical merit of surgical condition and doctor plays a part very important for the recovery of patient's Postoperative visual acuity.In this kind of surgical operation, due to the restriction of microscopy conditions or technical conditions, operating theater instruments need pass in and out anterior chamber of eyeball repeatedly, make in whole operation process, to maintain good, stable anterior chamber depth and Real-Time Monitoring intraocular pressure (IntraocularPressure, be called for short " IOP "), thus cause anterior chamber to shoal, disappear, corneal damage endothelium, iris, even cause posterior capsule rupture, bullous keratopathy and artificial intraocular lenses is caused to implant, operation safety and postoperative rate of recovering lost eyesight are reduced greatly, and then causes more serious consequence as blind.
In addition, some other intraocular surgery, stablizes to keep anterior chamber as vitrectomy, Secondary intraocular lens implantation, pupil moulding art etc. all need to maintain certain IOP value in art.In order to address this problem, operator often with its personal experience, by Intraocular tamponade viscoelastic agent in art or select the amount control IOP value of pumping liquid.But experienced doctor also cannot accurately know instant IOP value in art again, and keep normal intraocular pressure all significant for the prognosis of the smooth enforcement of performing the operation and intraocular surgery.
