Abstract Details

Purpose:

To compare the visual outcomes and the morphological features of 1.4 mm clear corneal incision (CCI) implanted with an INCISE MJ14 IOL vs. 1.5 mm CCIs stressed by the implant of an Akreos MI60 IOL 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:

Prospective study. To compare 30 eyes which underwent B-MICS and implanted with INCISE MJ14 IOL through 1.4 mm CCI (group A) with 30 eyes which underwent B-MICS and implanted with Akreos MI60 IOL through 1.5 mm CCI (group B), between April 2013 – July 2013. All patients underwent uneventful bimanual-MICS cataract surgery, have been operated by the same experienced surgeon. The IOL has been implanted through a 1.4 mm incision in group A and through 1.5 incisions in group B. The patients underwent a complete preoperative and postoperative ophthalmological evaluation, the CCIs have been examined through an anterior segment OCT (AS-OCT) and slit lamp camera at 1, 3, 7 and 30 days and 6 months after surgery. All clinical parameters have been reported and analyzed.

Results:

CDVA and mean endothelial cell density achieved optimal outcomes in both the groups, with no severe complications detected at the slit lamp examination along the follow up. No surgically induced astigmatism has been reported and an high percentage of patients achieved spectacle-free visual outcome. At the AS-OCT the only common evidences in both the groups were endothelial gaping and local detachment of Descemet’s membrane with a progressive reduction in the first week of the follow-up. No evidence of any morphological alterations has been reported at the AS-OCT examination at 6 months of follow-up.

Conclusions:

Both techniques appeared to be safe and effective with a rapid visual recovery and a high patients’ satifsfaction. The incisions in both the groups achieve a fast healing since the first week of follow-up and only temporary morphological alterations were detectable through anterior segment imaging. Group A incisions, probably due to a smaller incisions size at the time of implantation, compared to group B incisions which underwent an enlargement to 1.5 mm prior to the IOL implant, presented statistically significant fewer endothelial gaping (p-value 0.04) and local detachment of Descemet’s membrane (p-value 0.03) in the first postoperative days. B-MICS associated with INCISE MJ14 IOL implantation through 1.4 mm incisions is both minimally invasive and the corneal healing is faster, even comparing it to a similar surgical technique in which incisions are slightly larger.
