From the biggest aviary in Asia they went, sitting in buckets filled with ice to maintain them cool even though transported in air-conditioned vans.

A fast 30km (19-mile) drive later, the 3 king penguins and 3 Humboldt penguins had arrived at a clinic in Singapore’s east.

There, a 5-individual veterinary group had been waiting to carry out a delicate eye process, believed to be a globe very first for penguins.

The sextet underwent the removal of the cloudy lenses brought on by cataracts – a typical age-connected situation that develops in geriatric animals and hinders their vision – prior to getting custom-produced intraocular lens implants.

The lenses had been manufactured in Germany to match every penguin’s eye, primarily based on precise measurements, and took about two months to make, mentioned the Mandai Wildlife Group (MWG). The group manages some 21,000 animals, comprising just about 1,000 species, across 4 wildlife parks in Singapore.

“We noticed the cloudiness in their lens and [that they were] moving about like they had been obtaining difficulty seeing factors in front of them,” mentioned MWG veterinarian Dr Ellen Rasidi.

In the instant aftermath, the penguins had to remain out of water and in a separate den from the rest of their colony. Eye drops had been also administered twice everyday.

But just about 3 months right after the process, which took up to two.five hours for every penguin, the aquatic flightless birds can see clearly now, with a noticeable raise in responsiveness and activity levels.

MWG has carried out cataract surgeries on other geriatric animals like sea lions and orangutans in the previous. It has also adopted innovations such as printing 3D protective footwear for birds of prey, in order to treat a potentially fatal foot illness.

But Dr Gladys Boo, a veterinary ophthalmologist who led the process, reckons that it is probably the very first time penguins have effectively received intraocular lens implants, marking a “milestone” in veterinary medicine.

“As a bigger species, the king penguins have eyes substantial and steady adequate to hold the custom lenses in spot, so we decided to pursue this globe-very first process,” mentioned Dr Boo, who is 1 of only 3 men and women in South-East Asia certified by the American College of Veterinary Ophthalmologists, a renowned vet institution.

The surgery was complex by the one of a kind traits of penguins, such as a third eyelid, which protects their eyes underwater but had a tendency to close for the duration of the surgery.

MWG declined to reveal the expense of the surgery, but mentioned it was undertaken to increase the penguins’ high-quality of life.

The penguins had been very first diagnosed by Dr Boo for the duration of verify-ups carried out final August as element of the MWG’s senior animal care program, which has been delivering specialised care for elderly animals considering the fact that 2017.

It entails additional frequent wellness checks and specialised diets for 361 geriatric animals, as properly as distinct adjustments to their exhibits. Examples contain placing perches for geriatric birds on reduced levels for simpler access, and adding added padding or bedding in preferred rest locations.

The penguins reside at Singapore’s Jurong Bird Park, a well-liked tourist attraction which homes some five,000 birds.

King penguins hail from the South Atlantic and the South Indian Ocean and are the second-biggest of their type in the globe, even though Humboldt penguins come from South America. The former can reside up to 40 years in captivity, and the latter normally reside for 15-20 years.
