On target

Boxes piled up in Dr. Alexander Eaton's ophthalmology practice in Fort Myers are one clue there's more going on there than an ordinary medical office.

Like his colleagues, Eaton, director of the Retina Health Center in Fort Myers, sees patients all day. But at night, his offices transform into a workshop of medical devices.

Eaton's latest invention is a device that records how patients use their eye drops. A tiny camera snaps onto an eye-drop bottle and connects to a recording device the size of a cigarette pack. Each time patients use the eye drops, they record how well they accomplish the task.
