Abstract:
AIM: To create a live animal model of cataract for training in phacoemulsification.METHODS: The left eye of each dog was selected, and cataract was induced by puncturing the anterior capsule of the lens with the beveled end of the 26 gauge needle under general anesthesia. Phacoemulsification was performed in all the eyes following development of cataract.RESULTS: Ophthalmologic examination showed posterior cortical opacification started from day 5 to 7 after the induction and the complete cataract formation was observed at 75 days post the induction. The phaco-chop technique was practiced in all the dogs, followed by placement of intraocular lens. Vision was restored in all the dogs following the phacoemulsification.CONCLUSION: Considering the enormous losses caused initially by inexperienced surgeons while performing phacoemulsification, we suppose that this live animal model will be far superior to cadaver eyes that are commonly used for practice of phacosurgery.
