Résumé
We investigate the influence of scleral cautery during cataract surgery on limbal vascular density and remodeling using anterior segment optical coherence tomography angiography (AS-OCTA). Twenty eyes of 20 patients who underwent cataract surgery with a sclerocorneal incision were included. Patients were divided into two groups: non-cautery (n = 10) and cautery (n = 10). The area around the incision site was scanned using AS-OCTA before surgery and at 1, 3, 5, 7, 14, 21, 28, and 90 days postoperatively. Images were analyzed to depict conjunctival vasculature (surface to a depth of 200 μm) and intrascleral vasculature (depth of 200 to 1000 μm). Vascular density was evaluated using ImageJ software. In the non-cautery group, intrascleral vascular density significantly increased during the wound-healing period up to 21 days postoperatively. Cautery application completely diminished this effect, resulting in significantly reduced intrascleral vascular density in the cautery group compared to the non-cautery group until 5 days after surgery. On the seventh day and later, intrascleral vascular density in the cautery group recovered, but the vascular pattern did not return to its preoperative state even at 90 days after surgery. Conjunctival flap vascular density was reduced for 28 days after surgery, with cautery application further decreasing conjunctival vascular density. AS-OCTA enabled separate observation of conjunctival and intrascleral vasculature. Intrascleral blood flow significantly increased after cataract surgery, but scleral cauterization markedly blocked this effect. The vascular reconstruction process following cataract surgery continued for almost a month, with cautery application leading to prolonged vascular disruption and altered vascular patterns.
