Why I work in the eyecare industry

Michael O. is Sr. Technical Writer for Eyefinity/OfficeMate

I love working in the eyecare industry because I am so deeply indebted to it.

Most people don’t believe me when I tell them that I have worn hard contact lenses since I was a month old. You see, I was born with cataracts, and after undergoing four corrective surgeries as an infant, I am now aphakic. For those of you who follow this blog but are not doctors, aphakia is the technical term for having the natural crystalline lenses in one’s eyes surgically removed. While contact lenses are still the standard method of optical correction, these days, a cataract patient’s natural lens may be surgically replaced by a synthetic intraocular lens (IOL). Thirty years ago, IOLs were far too risky and expensive, thereby making contact lenses my only option.

Many people take sight for granted. You have no idea how precious sight is until your contact lenses are accidentally thrown out on Christmas Eve, or you can’t drive because you dropped a contact down the drain. Work can be interrupted. Vacations can be ruined. The possibility of suddenly not being able to see, which probably doesn’t occur to many people, keeps me on my toes.

The miracles of modern medicine and advances in eyecare have afforded me the opportunity to live a normal life. Of course, normal to me involves cleaning and securely storing my contact lenses every night and fussing with reading glasses everywhere I go. These are small prices to pay, however, considering that in past eras, my sight couldn’t have been saved at all.

It pleases me to write documentation for a company that supports what I would consider to be a noble industry, and I am proud to work with optometrists and ophthalmologists who have helped improve the daily lives of millions of people like me.

Bionic Eye – Testing Phase with Video!

Looks like someone (me) has an addition to a previous post about the bionic eye… CNN created a video package about this new technology, complete with an interview with test patient Barbara Campbell, 56. Take the video for a spin and see the promising results for yourself.

Technology. Love it or hate it – it continues to shape and change the world. Second Sight Medical Products - a company based in Sylmar CA, is in the process of harnessing technology to help those with macular degeneration or retinitis pigmentosa. On their workbench, a bionic eye.

How it works. The bionic eye was designed to be paired with a special set of frames – frames that contain a small video camera. These frames send visual data to the implanted bionic eye, which in turn activates the eye to create electrodes sent to the brain. The brain interprets these electrodes as visual queues, helping the patient interact with the environment.

Results thus far. Patients can find doors and follow the lines of the door. Most patients cannot read [normal size print], and of those who have the ability to read can only make out large letters. On an interesting side note – there are emotional benefits resulting from these tests, which are probably not on the lab sheets. Brian Mech (VP for Second Sight) notes, “There’s a lot of crying, a lot of smiling,” he says. “It’s a sensory input that they haven’t had in a very long time, and so they’re excited.”

Blogger’s take: Initially I was a bit underwhelmed by the results, but the methodology and implementation of the bionic eye was mind blowing! Albeit in the early stages, I’m sure they are going to have greater results with further testing and development. Now only if they could get the eye to shoot lasers…
