Comparison of morphologic features of clear corneal incisions created with a femtosecond laser or a keratome

摘要: Purpose To compare the morphology of clear corneal incisions (CCIs) created with a femtosecond laser (Catalys) or keratome (2.65 mm steel) during phacoemulsification using anterior segment optical coherence tomography (AS-OCT) and analyze intended versus achieved morphologic characteristics laser–generated CCIs. Setting Northwestern University Feinberg School Medicine, Chicago, Illinois, USA. Design Comparative case series. Methods Eyes CCIs age-matched eyes underwent AS-OCT 1 month after phacoemulsification. ImageJ software was used to evaluate images for CCI length, endothelial gaping, misalignment, Descemet membrane detachment. Results In group (20 eyes) (16 eyes), mean values were 1.99 ± 0.07 (SEM) 2.04 0.23 ( P = .39); 0.14 0.03 0.19 0.09 .03); 0.04 0.08 0.06 .022). No eye in 3 had detachment .04). Six 11 posterior wound retraction .02). The length 94.9% 2.1 mm, plane depth 93.3% 70%, side-cut angle 91.7% 45 degrees. Conclusion Femtosecond significantly lower detachment, than keratome-created within 10% depth, measurements.
