The impact of temperature on Ophthalmic Viscoelastic Devices and clinical implications - a pilot study: Temperature effect on Ophthalmic Viscoelastic Devices.

This pilot study confirms our clinical experience that OVD properties are affected by low temperatures, with increased viscosities at low shear rates and higher relaxation times.Cold OVD can cause greater resistance to initiation of IOL injection system forces (compared to warmer OVD). Excessively forced injection using cold OVD could contribute to inadvertent cannula detachment if incorrectly assembled, or uncontrolled IOL release leading to avoidable injury.
