Viscoelastic device are are biopolymers that play a critical role in modern cataract surgery.

• True

• False

Those are true about Cohesive OVDs except:

• create and maintain intraocularspaces

•  inflation of the capsular bag

• Higher molecular weight variants maintain intraocular space more effectively

• more difficult to remove from the eye

Those are true about dispersive Viscoelastic except:

• more difficult to remove from the eye

• tendency to retain air bubbles and lens fragments, compromising the surgical view.

• more adherent to surfaces

•  tend to promote iris prolapse in shallow

Those are ideal viscoelastic properties :

• Difficult removal

• Ease of infusion

• Endanger endothelium

• Obstruct aqueous outflow
