Contribution of black-and-white filters for optimizing visualization during cataract surgery

by: Lynda Charters

While the surgeons reported that the BW filter provided higher contrast during nucleus and viscous removal and posterior capsular polishing, they subjectively reported no significant advantage of using a BW filter.

French and Egyptian investigators, led by Otman Sandali, MD, collaborated to evaluate the use of black-and-white (BW) filters to optimize visualization during all phases of cataract surgery when using digital three-dimensional visualization systems. While the surgeons reported that the BW filter provided higher contrast during nucleus and viscous removal and posterior capsular polishing, they subjectively reported no significant advantage of using a BW filter.1

Sandali is affiliated with Centre Hospitalier National d’Ophtalmologie des XV-XX, Research Team 968, Institut de la Vision, Pierre & Marie Curie University Paris 06, Paris, and the Service de Chirurgie Ambulatoire, Hôpital Guillaume-de-Varye, Bourges, France.

“Good visualization during surgery is essential to ensure the safety of procedures,” the authors wrote. “There are certain conditions such as corneal opacities, corneal edema, and poor red reflex perception that can decrease the quality of visualization.”

Evaluation of BW images

The authors conducted a prospective study that included the first 40 patients undergoing phacoemulsification for grade 2 and 3 cataracts at Guillaume de Varye Hospital in January and February 2022. Twenty-six eyes underwent a phaco-chop technique and 14 eyes a sculpting technique.

The surgical images and videos were recorded with and without the BW filter at each stage of cataract surgery: before the incision was created and during the capsulorhexis, nucleus sculpting, fragment removal, cortex aspiration, posterior capsule polishing, and viscous removal……..
