Cataract Surgery (Phacoemulsification)
Dr. Corcoran has been performing cataract surgery since
1991. She has performed over 5000 cataract surgeries, in dogs, cats, birds,
rabbits, fish and even a loggerhead turtle! Dr. Corcoran’s success rate is
among the highest in the profession.
Numerous advances in surgical equipment, techniques, and
lens implant material have occurred over the years. Currently, cataract surgery
is performed with an ultrasound technology called phacoemulsification. With
this technique, a small, 3mm probe is placed into the eye and the tip of they
probe vibrates at over 40,000 times per second. This breaks down the cataract
proteins into a powder and they are sucked out of the eye through the small
probe tip. Following removal of the lens/cataract, a folding lens implant is
placed in the eye to restore both dogs and cats optimum vision. Occasionally,
an animal cannot have a lens implant. This can occur if there is not good lens
support. Poor lens support can be inherited in some breeds, such as Jack
Russell Terriers and Poodles, or more commonly can be due to the cataract being
left in the eye for a long time. Cats sometimes do not receive lens implants
due to pre-existing inflammation in the eye that can damage supporting
structures of the lens. In my opinion, dogs without lens implants seem to see
best at arms length and are blurry up-close and at distance but are by no means
blind as long as the eye heals normally.
While the success rate for cataract surgery is 98%,
complications can occur such as glaucoma, retinal detachments, and infection-
the same as in human cataract surgery. During the pre-operative exam, risks
factors will be identified and discussed for each patient and all questions
will be answered.
Dr. Corcoran has continued to update not only her cataract
equipment and surgical techniques over the years but also the anesthesia and
surgical, monitoring equipment. Since the average age of our surgical patients
is 12 years, we take anesthesia very seriously. Anesthetic safety is achieved
by using the safest anesthesia ventilating computers and state-of-the-art,
monitoring equipment. In fact, we take it so serious that we have 2 sets of all
the equipment and a very large generator for back up power. Dr. Corcoran has
been in practice since 1989 and has performed over 22,000 surgeries.
