OPHTHALMIC VISCOELASTIC DEVICES IN OCULAR SURGERY
OVDs display various levels of viscosity, pseudoplasticity and cohesion. The latest OVD classification established by Arshinoff and Jafari is based on the cohesion-dispersion index (CDI) and helps surgeons to predict its behavior during surgery. A combination of higher viscosity cohesive and lower viscosity dispersive OVD using the soft shell technique facilitates pressurization of the anterior chamber, ease of OVD removal and reduces IOP spikes following surgery.
