What is an emergency treatment for anterior lens luxation?

The correct answer is intracapsular lens extraction, which is the appropriate emergency treatment for anterior lens luxation in veterinary patients. Anterior lens luxation occurs when the lens dislocates from its normal position, which can lead to significant ocular complications such as glaucoma or retinal detachment.

Intracapsular lens extraction involves surgically removing the entire lens and its surrounding capsule, which is often necessary to prevent further damage to the eye and preserve the animal's vision. This intervention is crucial because once the lens is luxated, it can impair the normal function of adjacent ocular structures and pose a risk of secondary conditions that can threaten sight and overall eye health.

In contrast, therapies such as the immediate administration of corticosteroids or topical antibiotics may not address the underlying issue of lens luxation and its immediate consequences. Systemic pain relief might be necessary for comfort, but it does not correct the anatomical issue of the lens being misplaced. Therefore, prompt surgical intervention is the recognized approach to manage this ocular emergency effectively.
