Abstract Details


To analyze and compare morphological features of femtosecond laser (FSL) 1.4 mm clear corneal incision (CCI) with 1.4 mm manual CCIs in patients who underwent bimanual microincisions cataract surgery (B-MICS).


Institute of Ophthalmology, University of Modena & Reggio Emilia, Modena, Italy (Head: Prof. Gian Maria Cavallini).


This prospective, observational, comparative case series include 140 eyes who underwent FLS assisted B-MICS assisted (Group-A, 70 eyes) and B-MICS standard technique (Group-B, 70 eyes). All the CCIs have been examined at the slit lamp camera and through anterior segment OCT (AS-OCT) at 1, 3, 7 and 30 days and 6 months after surgery to look for endothelial gap (EnG), local detachment of Descemet Membrane (LDDM), Epithelial gap (EpG), Roof-floor misalignment (RFM) and loss of coaptation (LC). All clinical parameters have been reported and analyzed.


All patients have been operated by the same experienced surgeon and underwent uneventful surgery. The IOL has been implanted through a 1.4 mm CCIs in both the groups without any previous enlargement. There was no statistically SIA in both groups during the follow-up(p>.05). We found a higher incidence of EnG in group-B if compared with the group-A at 7 days of follow-up (p<.05). We did not found any statistical significant differences in any of the other morphological features at AS-OCT.


Both techniques appeared to be safe and effective with a rapid visual recovery and a high patients’ satisfaction. The incisions in both groups achieved a fast healing since the first week of follow-up and only temporary morphological alterations were detectable through anterior segment imaging at 6 months. FLS incisions are characterized by high safety and repeatability and appeared to be stable in the follow-up, adding precision in one of the most important steps of cataract surgery.
