title: Extracapsular cataract extraction: an analysis of 240 operations in dogs.
abstract: A total of 240 extracapsular cataract extractions were performed on 214 dogs at the University of Illinois between 1968 and 1980. Overall success of the surgery, defined as restoration of functional vision for at least 6 weeks after surgery, was 79%. The success rates, on the basis of various parameters, were compared with the following results. The greater the number of years experience each surgeon had, the greater the surgical success rate. In dogs in which a second eye was operated on, the overall success rate on the second eye was approximately 20% less than that for the study as a whole. There was a significant difference in success rates between surgery on congenital and juvenile cataracts when compared with surgery on diabetic and senile cataracts, the first being 15% higher than the second. The success rate was 18% less for lensectomy with concurrent iridectomy than for lensectomy without iridectomy. There was no significant difference in success rates among the 3 procedures for extracapsular extraction used in this study, nor among the various breeds studied. There was no significant difference in the success rate of surgeries on the left eye, compared with surgeries on the right eye.
