Cataracts cause vision loss in rabbits, often either spontaneously or as secondary to uveitis. This study considers the ophthalmic presentation, treatment, and outcome of phacoemulsification in seven pet rabbits: six presenting with lens cloudiness and one presenting with a white mass in the iris. Ophthalmic examinations revealed cataracts. The treatment plan was phacoemulsification. Encephalitozoon cuniculi was identified via an enzyme-linked immunosorbent assay technique performed on all rabbits. Ocular ultrasonography was performed to rule out retinal detachment. Phacoemulsification using the one-handed technique without intraocular lens implantation was performed in 8 of the eyes of the 7 rabbits. After surgery, the corneal wounds healed within 2 weeks. All rabbits were comfortable with opening their eyes and had a positive dazzle reflex and a clear visual axis, with no other severe complications (such as retinal detachment, intraocular hemorrhaging, or uncontrolled glaucoma) throughout the post-operative period. Postoperative complications consisted of corneal edema around the surgical wound (2 eyes: 25%): partial anterior synechiae (1 eye: 12.5%): partial posterior synechiae (5 eyes: 3 eyes before surgery and 2 eyes after surgery: 25%): posterior capsular opacities (3 eyes: 37.5%): and lens fiber overgrowths (2 eyes: 25%). In conclusion, successful phacoemulsification was achieved in the seven pet rabbits.
