Cataract can cause a horse to go blind and surgery treatment is the only treatments that may help the horse regain sight, although the surgery is difficult in horses owing to their large size. Equally important is the need to have frequent eye examinations after the surgery to ensure that all is healing well and that no complications are developing. If owners note any change in the eye after surgery they should not hesitate to contact the ophthalmologists. Some horses need some minimal amount of medication for several weeks after surgery. After surgery, glaucoma and endophthalmitis are potentially disastrous sequelae. In foals, immune compromise associated with Rhodococcus equi pulmonary abscesses may be a contributing factor in postoperative endophthalmitis, and chest radiographs should be taken as part of the surgical selection protocol in foals As in other species, post surgical posterior capsular opacity is a major problem in the horse and may necessitate a second surgery in an attempt to clear the visual axis by posterior capsulorrhexis. Potential complications of lens removal in the horse may include persistent or recurring intraocular inflammation, corneal ulcers, corneal cloudiness or edema and retinal detachments. Any of these complications may lead to discomfort, further treatment, visual impairment and/or blindness of the eye.
