Russian Ophthalmic Surgeons Perform Retinal Surgery Using 3D Visualization

Ophthalmic surgeons at the Penza Regional Ophthalmology Hospital have successfully performed a complex vitreoretinal surgery using 3D visualization technology. Similar procedures were previously available only at specialized federal clinics, but the new equipment and local expertise have made the operation accessible to patients in the Penza region, Penza Post reported.

Seeing the Eye in Three Dimensions

According to the hospital’s chief physician, Rashid Galeev, the 3D system enables highly precise diagnostics and surgical treatment—particularly for conditions involving the retina and vitreous body.

The surgery was led by Dmitry Logunov and Svetlana Danilkina. During the procedure, surgeons removed the vitreous body, repositioned a detached retina using a perfluorinated liquid, drained subretinal fluid, sealed the retinal tear with a laser, and then stabilized the retina with specialized medical gases.

Using 3D visualization allowed doctors to clearly see even the smallest anatomical structures of the eye in depth, improving precision and safety throughout the operation. Patients reported noticeable improvements in visual function following the procedure.

Advanced Care, Closer to Home

Doctors at the hospital emphasized that adopting advanced methods makes high-quality medical services more accessible outside major metropolitan centers. The Penza Regional Ophthalmology Hospital says it will continue to implement modern clinical practices to improve patient outcomes and recovery conditions.

Earlier reports also highlighted advances at HSE University, where researchers at its Saint Petersburg campus used artificial intelligence to uncover a stable, predictable link between eye movements and brain electrical activity. The algorithm can reconstruct gaze trajectories from EEG data—and vice versa—pointing to new possibilities in diagnostics and neuro-ophthalmology.
