<P>PROBLEM TO BE SOLVED: To provide an improved method for controlling intraocular pressure during ophthalmic surgery. <P>SOLUTION: This method for controlling intraocular pressure with a microsurgical system includes steps of: providing an infusion chamber containing an irrigating fluid; selecting an intraocular pressure; pressurizing the infusion chamber with a pressurized gas to provide irrigating fluid to a surgical device; measuring a flow rate of the fluid within a fluid line fluidly coupled to the surgical device; providing a signal corresponding to the measured flow rate to a computer; calculating a predicted value of the intraocular pressure with the computer in response to the signal; and adjusting a level of the pressurized gas in response to a signal from the computer to maintain the predicted value proximate the selected intraocular pressure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
