Falcon couldn't see. Now it flies with better eyes. Vet George Messenger and his wife Vet tech Shaela Messenger prepare to put Banner under anesthesiology before surgery (Concord Monitor)
Falcon couldn't see. Now it flies with better eyes.
Lexile

With a huff, and a puff, and a turn of her head to the side, Banner the lanner falcon announced yesterday at 4 p.m. that yes, she had made it through her surgery just fine, thank you. Would everyone please stop staring at her now?

Banner, who belongs to Jim and Nancy Cowan at the New Hampshire School of Falconry in Deering, is the first falcon in the world to have cataract surgery. Shes had a cataract in each of her eyes for almost two years, and without her sight, she hasnt been able to hunt or even fly.

Monday, a team of veterinarians and veterinary technicians carefully drugged her, cut into her cornea, removed the cloudy protein and implanted a uniquely designed artificial lens, and sewed her cornea shut again.

It amazes me how strong she is, Nancy Cowan said as she watched Banners clear dark eyes scan the crowded hallway. Lanners have a reputation as quiet birds, and I think it works for her, that temperament, that shes a bit sweeter than other falcons.

Banners ground-breaking surgery was originally scheduled for February, but was postponed several times as the team worked to perfect the shape and size of the artificial lens, and battled health problems of their own. George Messenger of Fisherville Animal Hospital, who supervised the anesthesia, underwent heart surgery this summer, and Ruth Marrion, a Massachusetts-based veterinary ophthalmologist, performed the surgery while seated, because she broke her leg last month.

Seven people hovered over Banner in the operating room, and dozens more in Montreal, California, Ohio, Germany and Abu Dhabi were involved in designing the artificial lenses, which had to match precise measurements.

I-Med, a Canadian ophthalmology supply manufacturer, donated the lenses, which are about 6 millimeters wide. Capital Area Veterinary Emergency Services in Concord donated the operating room and supplies. Messenger and Marrion both donated their time and at several appointments over the summer preparing for the main event.

A lens has two parts: a thin covering called the capsule, which is like a baggie, and the contents, which are normally clear like a raw egg white. The dense contents help the eye focus light and draw crisp images to the optic nerve.

A lens with a cataract is like a baggie filled with cooked egg white, letting only limited light through to the nerve.

Marrion cut a tiny hole through the baggie and vacuumed out the opaque contents. Then, she folded the flexible artificial lens, slipped it through the small hole and placed it in the baggie, which should hold it in place as if it were spring-loaded.

The hourlong surgery went smoothly and the vets and technicians chatted as each step went exactly according to plan.

But Messenger wasnt ready to celebrate until after the very last step removing the breathing tube in Banners throat that allowed them to pump anesthesia to her. The process is crucially important and incredibly delicate, he said.

Its called last stitch syndrome: Youre suturing someone up and on that last stitch, it could all go wrong, he said.

Then, veterinary technician Shaela Messenger wrapped the bird in a pink towel and carried her out into the hallway. The Cowans and all of the veterinary staff smiled and chatted.

But a few minutes later, Shaela calmly whispered to George Messenger that the bird wasnt waking up, and the two walked silently and purposefully to the incubator. In the dark heated cage, Banner could stay warm without being held, and might be more likely to wake up, they said.

Cowan pulled on her falconers glove and shifted her weight impatiently from one foot to the other. Banner, still wrapped in the towel, opened her feathered eyelids halfway and waggled her head side to side. Then, she stood, wobbling a little, puffed out her chest and stretched her wings, filling the cage.

Within minutes, Cowan reached into the incubator and loaded Banner onto the glove.

Theyll have to give her anti-inflammatory eye drops for a few weeks and make sure her eyelids dont become too irritated by the sutures in her corneas. The Cowans both cried with relief at the first sign Banner had survived the surgery.

When we first started looking for help, we heard a lot of anecdotal, well, it cant be done, Jim Cowan said.

As Nancy held the bird on her glove, he shook a leather tassel a few feet away, and smiled gleefully when Banner turned toward it.

You can see something all right, he said. You can see something.

Critical thinking challenge: What did Dr. Messenger mean by Last Stitch Syndrome? Could it apply to any process other than surgery? If so, what?

    Dr. Messenger meant that your concluding your surgery with the last stitch and by thinking it is all right. you could mess up and It could all go wrong. I don't think the last Stitch syndrome could be used for anything other than surgery because it means your ending the surgery with the last stitch and your nervous as it is especially to mess up.

    WOW! This article was kind of inspiring, because a falcon that had no vision survived and had surgery on both eyes. It kind of makes you realize how advance our technology has became over the past years. If a bird was blind;- there probably was, they would just die and couldn't get this eye surgery. this Falcon is very luck and hope it has a safe flight!

    Summary with the 5W's
    Banner the lanner falcon had a cataract in his eye. The owners, devastated decided to look for help for the bird. They finally found someone in Concord, New Hampshire who was willing to take on the surgery in the Fisherville Animal Hospital and Bird Clinic. Normal lenses are like baggies with uncooked egg whites in them, while one with a cataract is like a baggie with cooked egg whites in it. Those "cooked egg whites" were causing Banner to lose his sight, thus causing him to not hunt or fly. Originally, the surgery was scheduled for February, but it was moved to Oct. 2, because the scientists involved had not developed a lens the right shape and/or size for the bird. Now, Banner and his owners are living happily.

    The main thing of this article is that the falcon had surgery. She had made it through her surgery just fine. She had surgery from her eyes. She was the firs falcon to get surgery. The falcon couldn't hunt and eat. But know thanks to the people that save the falcon. Know she can see and hunt for she can eat.

    I think that this is a very interesting story that a falcon had cataracts. I did not know that birds could get that. I like the fact that people care enough to actually help a bird to be able to see.

    I had no clue that we had artificial lens that we can implant into birds. It amazes me that we have the technology to do things like this in today's society

    I think it's cool that they helped the eagle. It's the little things that count that show people care, I think the next however is helping people more than Animals

    I think it is really cool for a bird to have cataract surgery and be able to survive. I have heard from several other people that cataract surgeries are extremely difficult. I hope that the falcon has a long, flight-filled, high-soaring, sight-seeing life.
