KEY TAKE-AWAYS

OVDs are essential surgical aids that create and maintain space, coat surfaces, protect ocular tissues, and facilitate the surgical procedure^1,2

OVDs display various levels of viscosity, pseudoplasticity and cohesion^1,2

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 surgery¹

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^3,4
