Abstract:

Intraocular pressure (IOP)  significant varies during cataract phacoemulsification. At present, the studies of IOP in phacoemulsification  are mainly carried out using sensors connected with the animal or human eye anterior chamber or vitreous cavity, or implemented by sensors placed on the central cornea, so that the IOP and ocular blood flow can be measured in real-time fashion during operation. The results showed that intraoperative IOP was closely related to the height of the perfusion bottle and fluctuated strongly and constantly. Optic nerve and retina can be damaged on account of sharp increases and changes in intraoperative IOP. The surgeons should pay attention to the changes of intraoperative IOP, especially for patients with advanced glaucoma and ischemic optic neuropathy. In the case of maintaining the anterior chamber stability, reducing bottle height will decrease optic nerve and retinal damage and increase surgical safety.  (Int Rev Ophthalmol,  2017,  41:   106-109)
