Success Rates of Unilateral vs. Bilateral Cataract Extraction in Dogs

Abstract

Postoperative results of 113 unilateral and 77 bilateral extracapsular cataract extractions (EC-CEs) in dogs were evaluated retrospectively. Restoration or improvement of functional vision was achieved in 79.6% of the eyes in dogs with unilateral extraction and 85.7% of the eyes in dogs with bilateral extractions at weeks 4 to 6. Complications occurring 6 weeks to 9 months after lens extraction lessened the surgical success rate in both groups. Twenty-six percent of the dogs in which bilateral lens removal was performed suffered complications resulting in surgical failure in one eye. When using the criterion that one or both treated eyes had functional vision, a short-term success rate of 98.7% was found for bilateral extractions.

Update on veterinary cataract surgery

“…The concern with unilateral surgery in a patient with bilateral cataracts is that the un-operated eye remains at risk for chronic LIU, lens luxation, retinal detachment and glaucoma and these may require medical and/or surgical intervention negating any cost savings [4,24]. Conversely, bilateral surgery has the advantages of restoring sight to both eyes with a single anesthetic episode and convalescent period, lower overall costs when compared with those of two unilateral surgeries, and a higher percentage of patients who regain vision from one or both eyes [25].…”

Avaliação da composição molecular da cápsula anterior da lente de cães idosos com catarata de alto risco

“…A realização da técnica cirúrgica de FACO em cataratas hipermaduras ainda é a melhor opção cirúrgica, já que a lente pode apresentar alterações significativas em sua estrutura capazes de comprometer o sucesso cirúrgico (Davidson et al 1990). Venkatesh et al (2010) observaram que a FACO em cataratas hipermaduras também são frequentemente realizadas em pacientes humanos atendidos na Índia, um país em desenvolvimento como o Brasil.…”
