Blue eyes have historically been a significant measure of attractiveness, and although they’re commonly found among actors and models, only 17% of the global population has them. For the majority of people, approximately 80% of the population, blue eyes have been attainable only with the aid of colored contact lenses or artificial iris implants. But that will soon change with the introduction of a new medical procedure, pioneered by California company Stroma Medical, that can turn brown eyes blue.

The laser procedure works by eliminating the melanin -, the pigment that also colors hair and skin – from the surface of the iris, which then allows light to enter and scatter in the stroma, the fibers seen in light-colored eyes. The effect is similar to Rayleigh scattering, in which wavelengths of sunlight hit much smaller molecules in the air and then scatter, which makes the atmosphere appear blue.

People unhappy with the way they look have been using plastic surgery to change their appearance for years, but now they can take their obsession to a whole new level by changing the color of their eyes through a controversial procedure known as artificial iris implant.

Pioneered by Dr. Kenneth Rosenthal, as a way to correct various eye defects (heterochromia, ocular albinism, etc.), the artificial iris implant procedure is now also being advertised as cosmetic surgery for people who want to permanently change the color of their eyes. The artificial iris is a thin, non-toxic prosthesis made of the same ophthalmic grade silicone used in intraocular lenses. Since the fake iris is very flexible, it can be folded and inserted into the eye through a peripheral corneal surgical incision about 2.8 mm long, and unfolded over the natural iris. According to the website of BrightOcular, the company behind the increasingly popular cosmetic eye surgery, the procedure is “short, safe, and painless”, taking about 15 minutes for each eye. The surgery has a purely cosmetic purpose, it does not fix vision defects, so patients will still need to wear refractive instruments to correct their vision. Unlike other laser-based procedures that remove a layer of melanin from the iris in order to permanently change its color, BrightOcular claims their iris implant can easily be removed in case of complications or if the patient so desires.
