The argument for two‐handed cataract surgery in veterinary ophthalmology

Abstract Despite access to contemporary phacoemulsification technology and the strong shift to two‐handed nucleofractis techniques in human medicine, a one‐handed, single incision approach has persisted among Diplomates of the American College of Veterinary Ophthalmologists. The perpetuation of techniques such as bowl‐sculpting one‐handed phacoemulsification in veterinary medicine is multifactorial; it is likely associated with the lack of two‐handed training in residency programs, the challenges of learning on complex cases, the ease of teaching one‐handed versus two‐handed techniques to a resident, and the lack of specific instrumentation available designed for larger lens size, among other factors. Additionally, variation in globe and palpebral fissure size in veterinary patients complicates the training of cataract surgery. Finally, many mentors or mentors' mentors, were trained alongside previous generations of MD surgeons who performed bowl sculpting techniques during the transition from extracapsular cataract extraction to phacoemulsification, and understandably, are not comfortable teaching a two‐handed technique consistently. The authors have observed an unwillingness to convert from one‐handed to two‐handed technique in the post‐residency career for most veterinary ophthalmologists; this could be due to the high expectations becoming a specialist, especially when the stakes are as high as in phacoemulsification. Therefore, the authors advocate for hands‐on training in multiple nucleofractis techniques, including two‐handed methods during residency training. Simply put, if residents are not trained and comfortable with two‐handed techniques by the end of residency, they are less likely to make further changes later in their career. In this article, we aim to explore the proposed rates of one‐handed versus two‐handed mentors currently teaching veterinary phacoemulsification, the history of cataract surgery, and to discuss the benefits of two‐handed nucleofractis techniques. The authors will also illustrate and provide videos as well as some tools for veterinary ophthalmologists wishing to learn two‐handed techniques.
