Abstract Details

Purpose:

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).

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
