How an Upgradeable Ophthalmic Microscope can Benefit Surgeon and Hospital

Interview with Dr. Seenu M. Hariprasad, University of Chicago


Proveo 8 ophthalmic microscopeMost ophthalmic surgeons agree that optimal visualization is a key criterion when choosing a surgical microscope. However as more and more digital technologies enter the OR, the microscope is becoming more than a pure optical tool.

Seenu M. Hariprasad, MD, is the Chief of the Vitreoretinal Service, Director of Clinical Research and Shui-Chin Lee Professor of Ophthalmology and Visual Science at the University of Chicago. He believes the Proveo 8 ophthalmic microscope represents the first of a new generation of ophthalmic microscopes that not only deliver outstanding optical quality, but also serve as a flexible and upgradeable platform for the integration of digital imaging technologies.

What do you see as the advantages of the modular design of the Proveo microscope?

Dr. Hariprasad: Eleven years ago, my hospital purchased a scope for retina surgery that could not be upgraded. In contrast, the Proveo 8 ophthalmic microscope can be used for anterior and posterior surgeries, and expanded and upgraded through time. The ability to expand the scope is essentially the ability to extend its life. A facility makes a major investment in a microscope, and when a new tech­nology comes along in a few years, a new component can be added to the scope. If the scope is not expandable and cannot accept the new compo­nent, then the facility has to replace the scope at a much greater expense.

With rapidly evolving medical technologies, we do not know what will come along — even in the near future — so it makes sense to have the ability to expand. One example is intrasurgical OCT, an exciting new devel­opment from a retina perspective that is in its infancy today. The Proveo 8 microscope is built to accept an integrated OCT component for future integration. As well as the possibility to upgrade with future developments, the microscope also enables sophisticated recording devices, Toric Alignment Navigation, and 3D viewing to be added at any time.

The Proveo 8 microscope is designed for anterior and posterior surgeries – what benefit does that offer you and your hospital?

Dr. Hariprasad: The versatility for different ophthal­mic surgeons is an enormous advan­tage because it doubles the potential use and return on a large invest­ment, while potentially eliminating the need for two microscopes, depending on the setting and volume. Hospitals are happy to get something that all doctors can use.

How would you sum up the advantages of the Proveo 8 ophthalmic microscope?

Dr. Hariprasad: As a retina surgeon, I rely on my ophthalmic microscope for high-resolution visualization during surgery. I’m excited about the Proveo product as it offers the latest visualization innovations while also allowing existing and future digital imaging technologies to be integrated into a sleek, modern design. A range of next-generation features may well make the Proveo 8 an essential scope for posterior segment surgeons.

How Intrasurgical OCT can Impact the Surgical Approach to Membrane Peeling

OCTWhen treating patients with vitreomacular traction (VMT), peeling of the inner limiting membrane (ILM) or an epiretinal membrane (ERM) is often indicated. Successful outcomes depend on precise surgical maneuvers as well as the surgeon’s experience in order to assess whether the entire membrane has been removed, as this is crucial for successful release of traction. Having as much visual information as possible helps the surgeon confidently perform membrane peeling. It also supports identification of residual membranes, and examination of the retinal morphology immediately following the procedure for complications such as macular holes, sub-retinal edema or residual traction. High-resolution cross-sectional imaging provided by intrasurgical optical coherence tomography (OCT) can provide vital anatomic information to surgeons during retinal procedures, helping to guide surgical decision-making.

Showing different steps of removing an ERM to resolve VMT, the following videos captured with EnFocus intrasurgical Optical Coherence Tomography demonstrate how visualization of the membrane can impact the surgical process of membrane peeling. Imaging with EnFocus intrasurgical OCT supports identification of an epiretinal membrane (ERM) causing vitreomacular traction (VMT) and helps guide intrasurgical decision-making during membrane peeling:


Vitreomacular traction (VMT) and Epiretinal membrane (ERM)

Pre-operative retinal scan shows vitreomacular traction (VMT) and Epiretinal membrane (ERM).

 OCT reveals residual membrane

After ERM peeling, OCT reveals residual membrane creating longitudinal traction.

OCT confirms that the membrane creating longitudinal traction has been severed

After further surgical intervention, OCT confirms that the membrane creating longitudinal traction has been severed and no macular hole created. The surgeon decides air exchange is not required, sparing the patient from prone positioning.
