Cataract is an important ophthalmic disease in dogs. Treatment is often surgical, but the removal of the lens produces hypermetropy and vision is impaired. Correction is usually performed with an intraocular lens (IOL). This study had the purpose of obtaining data for intraocular lens production in order to use in aphakic dogs, because cataracts is a very common ocular disease in this species, and surgical treatment is mandatory. One hundred and twenty dogs of both sexes, clinicaly healthy and free from ophthalmic disease were used. A keratometric study and a biometric study, using A-mode ultrasonography, were used. Some of these measures were determined using a specific formula for evaluation of the IOL dioptric power, to substitute the affected lens. The IOL dioptric power was correlated with weight and sex and left and right eyes. Although some differences were observed between left and right eyes and males and females, body weight was the most important variable to influence IOL dioptric power in dogs.
