Illustration Mundo had an interview with Klassen earlier this year.

Man recovers vision after 12 years by implanting tooth in eye

scrutiny — Sat, 18 Jul 2009 22:21:06 -0800

Recently, a man's sight was returned to him after losing it for 12 years. How did he do it? Surgeons drilled a hole through one of his canines, put a lens in it, and implanted the construct in his eye. The specific surgery is called Osteo-Odonto-Keratoprosthesis and was first pioneered in Italy in 1963. Essentially, a tooth and a small portion of the jaw is removed from the patient. A small hole is drilled into the tooth and a lens is attached inside. The tooth construct is implanted in the cheek to allow it develop a blood supply, and then later is implanted into the eye. Despite how unwieldy this procedure seems, it has a shockingly high success rate over time. In this survey of 181 patients, 85% retained functional use of their eye after 18 years, with approximately 55% retaining the best postoperative functionality.

eyevolution

Although the evolution of the eye is often pointed to by evolution's skeptics as evidence of design, biologists have been quick to point out evidence to the contrary. Today, Julian Partridge of Bristol University's Ecology of Vision Research Unit has brought to light evidence of a Pacific fish that has evolved biological mirrors for navigating murky water.

What Good Is Half A Machine?

DU — Tue, 09 Dec 2008 05:24:37 -0800

One of the classic arguments against evolution by natural selection is "what good is half an X?" where X is an eye, a wing or some other complex body part or system. Directly responding to the implicit challenge some researchers have been not just figuring out how X could have evolved, but actually evolving new complex machines (previously). The basic ideas are so simple that web versions (explanation and discussion) have been popping up.

The 123 Year Old Eyes

Bernt Aune's corneas are 123 years old, which possibly makes them the oldest living human tissue on record. Eduard Zirm performed the first successful corneal transplant was in 1905, and was soon followed by hundreds of successful transplantations. The Eye Bank Association of America was established in 1985, in part to provide regulation of eye banks in the US. Over 100 banks now operate in the country, and over 400 banks exist worldwide. Until recently, most US eye banks only accepted eye tissue from donors aged 65 or less; a new study has shown that corneas from donors aged 66 to 75 can be used just as well. "This could expand the donor pool by 20 to 35 percent." Here is a pamphlet [pdf] on the history of corneal and eye transplants from the EBAA. A personal log of a cornea transplant.

Eyescapes by Rankin [nsfw]. Rankin's home site [flash], his Wikipedia entry. The anatomy of the iris l Crypts of Fuchs l Pupillary ruff l Contraction furrows l pigment dots l color scale l Wolfflin nodules l factor structure Eye color, or more correctly, iris color is due to... The visible features of an iris arise in the trabeculum, a meshwork of connective tissue that displays arching ligaments, crypts, contraction furrows, a corona and pupillary frill, coloration, and sometimes freckles. The striated anterior layer covering the trabecular meshwork creates the predominant texture seen with visible light (see examples here), but all of these sources of radial and angular variation taken together constitute a distinctive "fingerprint" that can be imaged from some distance.

Glassy eyes. The German art of glass eye blowing was developed in Lauscha, Germany in 1835 using cryolite glass. It's a dying art, Australia has only one practitioner in the country. This slow loading but fascinating video [sorry, Windows media] shows the process (apparently in the time it takes to drink a cup of tea). With a family history in the trade and a pioneer in contact lens development, this man's daughter feels that her father is in need of a bit of recognition.

Remember that Citroen Transformer breakdancing? Sure, some of us love it because it was a sweet ride and deep down inside, we all want to be sporting an Autobot. Of course this begs the question "who could actually afford one?"
Well now thanks to consumers driving down prices, there is an alternative.

Scientists in the USA have discovered [NYTimes] a new cell in the eye responsible for resetting the biological clock. Its being called "heretical".. Not every day, Dr. Provencio said, do scientists find a new body function.
