Residual Fragment Assessment with the Proveo 8 Intraoperative OCT


With its high precision and perfect synchrony to optimize your view, the Proveo 8 intraoperative OCT imaging system supports ophthalmic surgeons in providing the highest standard of care in eye surgery.

In the brief video presented below, Dr. Rachid Tahiri, an ophthalmic surgeon at the Centre d’Ophtalmologie in Granville, France shares his experience in using Proveo 8 intraoperative OCT in cataract and retinal surgery.

Key Learnings

The Proveo 8 ophthalmic microscope with built-in intraoperative OCT is an advanced imaging solution designed to improve the surgical workflow and achieve the highest level of precision during anterior and posterior segment surgery.

In the video below, Dr. Tahiri shares his impressions of using the Proveo 8 intraoperative OCT imaging system in cataract surgery. Specifically, Dr. Tahiri highlights the advantage of using this imaging solution in detecting and addressing residual lens fragments, which can be difficult to visualize due to being hidden behind surgical incisions or edema. He explains that using Proveo 8 intraoperative OCT is useful in locating residual lens fragments, improving surgical outcomes, and reducing the risk of postoperative complications and readmission for secondary surgery.

About EnFocus

EnFocus is an intraoperative OCT for surgical microscopes. It allows to visualize subsurface details with high definition real-time images of the posterior and anterior segments. In addition to its benefits in keratoplasty and cataract surgery, intraoperative OCT can aid decision-making in cornea, glaucoma and retina procedures. It is also an essential tool in the application of gene therapies. EnFocus can be combined with the Leica Proveo 8 or M844 ophthalmology microscope for comprehensive visualization.

Transcription of the Presentation


[00:06 - 00:17]

Hi, my name is Rachid Tahiri. I am an ophthalmic surgeon from Granville in Normandy, France. My main topics are cataract and retinal surgery.

Residual lens fragments assessment

[00:17 - 00:32]

Beyond retinal surgery, which is a classical indication, intraoperative OCT may be useful in cataract surgery, especially to access residual lens fragments.

[00:33 - 00:56]

In this example, at the end of the surgery, I have a doubt about the presence of a residual fragment. Thanks to intraoperative OCT, I was able to highlight a residual fragment. It was quite a big fragment hidden behind the edema of the main incision.

[00:57 - 01:19]

In this second example, the smaller residual fragment was hidden behind the secondary incision. The problem is that corneal edema at the level of the incisions may reduce their visibility. That’s why using intraoperative OCT could be very useful.

[01:20 - 01:44]

What I usually do is to perform a 360° circular scan of the anterior segment. Using the microscope pedal, it is possible to go back over the sections to analyze the images. In this case, there was a residual fragment hidden behind the secondary incision edema.

[01:45 - 01:54]

And in this other case, there was a little residual fragment in the iridocorneal angle.

Benefits of intraoperative OCT

[01:55 - 02:26]

In my experience, intraoperative OCT could be very interesting in cataract surgery. We can visualize residual fragments; we can avoid readmission for secondary surgery a few days and weeks later, and we can reduce many postoperative complications. So, intraoperative OCT is a great tool to improve the quality and perfection of cataract surgery. Thank you for your attention.
