6. The "Retinal Potentiogram" is a standard examination item before cataract surgery to confirm whether the dog has common hereditary retinal disease or reduced retinal function. If the retinal potential map is abnormal, it means that the retinal nerve function has been hindered, so there is no need to perform another surgery. Choosing the appropriate case is very important for the success rate of cataract surgery. First, a thorough medical history and physical examination should be performed on the animal, such as whether the animal has diabetes, liver disease or kidney disease or blepharitis that affects anesthesia. Secondly, a thorough ophthalmic examination of the animals should be conducted. The animal's temperament will also have a significant success rate after cataract surgery. If the animal is too sensitive, it is impossible to perform reasonable eye medication after the operation. Therefore, for those dogs with obvious offensiveness, the success rate of surgery may decrease. Detailed ophthalmic examinations of animals should be performed before cataract surgery, including: detection of tear volume, examination of eye attachments, intimidation tests, direct and indirect pupil reflexes, and measurement of intraocular pressure. If these examination items are normal, a fundus examination after the mydriasis should be performed. Check the cornea for opaque areas that may affect intraocular manipulation. In addition, if there is edema in the corneal before the operation, it means that the corneal endothelium may have decompensation. At this time, the degree of edema in the corneal after the operation may be more serious. Check for excessive pigmentation, iris adhesion and uveal valgus caused by LIU. Check whether there are water radiance and posterior corneal deposition in the anterior chamber. In addition, it is very important to examine the retinal potential map of the affected eye, because if the retinal function of the canine has been lost, even if cataract surgery is performed, the affected eye cannot recover its vision after the operation, and this problem is not uncommon in clinical practice. Only dogs whose examination items are completely normal can undergo surgery.
