What causes Post op cataract vitreous humor leak?

A post-operative cataract vitreous humor leak can occur due to several factors, primarily related to surgical trauma or complications. During cataract surgery, manipulation of the eye may lead to a disruption in the vitreous gel, particularly if there is an inadvertent breach in the vitreous cavity. Additionally, inadequate sealing of the incision or excessive intraocular pressure can contribute to this leakage. Post-operative inflammation or complications such as retinal detachment may also increase the risk of vitreous fluid leakage.
