Evaluation of corneal incision in femtosecond laser-assisted phacoemulsification

Purpose: This study aimed to evaluate the accuracy and quality of healing of main corneal incisions in femto second laser procedures in cataract surgery. Methods: It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery w...

Methods: It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery were separated into two groups in this prospective, nonrandomized study: Femto group, with incisions automated by femtosecond laser (18 eyes), and Phaco group, with incisions made using a keratome (19 eyes). The planned incisions were 2.2 mm wide and 1.65 mm long. The length of the incision and prevalence of endothelial gap, endothelial misalignment, and localized Descemet Membrane Detachment (DMD) were compared. Results: The mean incision length was statistically higher in the Femto group in two examinations: 1.64 mm ± 0.16 vs. 1.43 mm ± 0.30 (p = 0.001) in Exam 1 (between 2 and 4 days) and 1.58 mm ± 0.22 vs. 1.27 mm ± 0.34 (p < 0.0001) in Exam 2 (between 1 and 3 months). No eye presented an endothelial gap in Exam 2. The endothelial gap was higher in the Femto group in Exam 1. In the two examinations, endothelial misalignment was lower in the Femto group, whereas the incidence of DMD was lower in the Femto group in the two examinations. Conclusions: Automated incisions with femtolaser presented a higher mean length and lower DMD prevalence compared to manual incisions with a keratome.Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo2025-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.usp.br/clinics/article/view/23807410.1016/Clinics; Vol. 80 (2025); 100572Clinics; v. 80 (2025); 100572Clinics; Vol. 80 (2025); 1005721980-53221807-5932reponame:Clinicsinstname:Universidade de São Paulo (USP)instacron:USPenghttps://revistas.usp.br/clinics/article/view/238074/214938Copyright (c) 2025 Clinicsinfo:eu-repo/semantics/openAccessHorta, GuilhermeKara-Junior, NewtonHorta, Rog´erio2025-09-12T14:07:15Zoai:revistas.usp.br:article/238074Revistahttps://www.revistas.usp.br/clinicsPUBhttps://www.revistas.usp.br/clinics/oai||clinics@hc.fm.usp.br1980-53221807-5932opendoar:2025-09-12T14:07:15Clinics - Universidade de São Paulo (USP)false
