Abstract Details

Purpose:

To evaluate the efficacy and safety of 1.4mm femtosecond laser-assisted bimanual microincision cataract surgery performed by an experienced surgeon and compare the results with those obtained with 1.4 mm B-MICS standard technique.

Setting:

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

Methods:

This prospective, observational, comparative case series include 60 eyes who underwent B-MICS assisted by femtosecond laser (Group A, 30 eyes) and B-MICS standard technique (Group B, 30 eyes). Patients with any ocular pathology that could have affected visual outcomes during the follow up period were excluded. Best Corrected Visual Acuity (BCVA), Surgically Induced Astigmatism (SIA), corneal thickness, endothelial cell count, macular thickness (MT), AC-OCT of corneal incisions were performed at 1 day, 7days, 1 month, 6 months. Intraoperative parameters (ultrasound power, effective phacoemulsification time) and complications during and after surgery were analyzed.

Results:

Mean EPT was 3.48±1.98sec in Group A e 5.76±2.1sec in Group B. Mean Total Surgical Time was 20.75±4.5min in Group A e 12.62±4.37min in Group B. One month follow-up: mean BCVA improvement was 0.48±0.22 in group A, 0.46±0.19 in group B. No statistically SIA neither corneal pachymetry changes. Statistically significant endothelial cell loss (mean loss 493.37±492.83 cells/mm2) between the 2 groups. Mean microincisions’ length and inclination for Group A and Group B were respectively 1348±163 and 1429±253 um and 141.8±6.4° and 145.5±6.2°. 23% of endothelial-gap, 6% of posterior-wound-retractions, 3% of epithelial gap and 5% of Descemet-stripping.

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. B-MICS associated with femtosecond laser is minimally invasive and the corneal healing is faster, compared with the standard B-MICS.
