Use of phacofragmentation for cataract removal in horses: 12 cases (1985-1989).

This research paper chronicles the outcomes of employing phacofragmentation, a surgical procedure, to get rid of cataracts in horses. The study reveals a general success in sight restoration but also notes the occurrence of several complications post-surgery.

Study Overview

• The study examined the medical records of 12 horses, from which cataracts were removed using a surgical process known as phacofragmentation. The age span of the participating horses ranged from 2 months to 15 years, and a total of 16 eyes were treated.

Post-Surgery Complications

• After the surgery, there were several complications encountered. Corneal ulcers, a common issue often caused by injury or infection, appeared in 13 eyes.
• Diffuse corneal edema, which is a swelling that can blur vision, occurred in 5 eyes.
• Uncontrollable uveitis, an inflammation of the middle layer of the eye, was detected in 3 eyes.

Follow-up and Results

• All horses had a follow-up duration ranging from 1 month to 3.5 years post-surgery. This is to track the recovery progress and detect any long-term complications.
• Based on the feedback from owners or veterinarian evaluation, visual results post-surgery were deemed ‘good’ in 10 of the horses, suggesting that the operation was largely successful at restoring vision or relieving symptoms of cataract.

Implications of the Study

• This study demonstrates the potential of phacofragmentation as a viable method for cataract removal in horses. However, it also underscores the necessity for thorough aftercare and monitoring, due to the likelihood of complications such as corneal ulcers, corneal edema, and uncontrollable uveitis.
