Lens luxation in cats can occur secondary to anterior uveitis (inflammation of the inside of the eye).

Uveitis (inflammation of the eye) causes the pupil to constrict (miosis) and trap the lens in the anterior chamber, leading to an obstruction of outflow of aqueous humour and subsequent increase in ocular pressure (glaucoma).

[1] Better prognosis is valued in lens replacement surgery (retained vision and normal intraocular pressure) when it is performed before the onset of secondary glaucoma.

This type causes fewer problems than anterior lens luxation, although glaucoma or ocular inflammation may occur.

[6] A nonsurgical alternative treatment involves the use of a miotic to constrict the pupil and prevent the lens from luxating into the anterior chamber.
