Designed for use in the OR, the Zeiss OPMI Lumera 700 surgical microscope has stereo coaxial illumination technology and Carl Zeiss optics. I use it primarily for cataract surgery because it provides great visualization. The coaxially sighted corneal light reflex (CSCLR), which is unique to this device, helps to center IOLs. The Lumera 700 has all the features of a modern microscope, including foot pedal control and excellent, customizable lighting.
I’ve been using the Zeiss OPMI Lumera 700 Surgical Microscope for about five years. At the time I acquired the Lumera, I also considered the Leica microscope. But I ultimately chose the Lumera because of its ability to provide a great red reflex. Ergonomically, it was also better in terms of how it handled in the operating room. With only one joint in the arm, the microscope folded away consistently each time.
What I like best about the Lumera is that it gives me great visualization for surgery. I also like that it has stereo coaxial lights, which I can use to help align toric and diffractive multifocal IOLs. The Lumera also allows me to customize my lighting, such as the amount of light I want to divert to the coaxial lights versus the diffuse illumination light.
While the Lumera microscope does not have any significant challenges that I’ve identified, one thing that I wish could be improved is the ability to isolate a single coaxial light for fixation purposes.
I would definitely recommend the Lumera microscope to my colleagues. It gives great illumination and visualization during surgery, and it just plain works.
