Abstract Details

Purpose:

The purpose of the study was to compare the corneal morphology and topography after femtosecond laser-assisted cataract surgery versus micro-incision cataract surgery versus small-incision cataract surgery.

Setting:

Chair and Clinical Department of Ophthalmology, School of Medicine and Division of Dentistry in Zabrze, Medical University of Silesia in Katowice, Poland.

Methods:

87 patients undergoing phacoemulsification surgery were included in the study. Inclusion criteria were: cataract stage II-IV, no accompanying ophthalmic and systemic diseases which presence or treatment affect cornea. Patients were randomly selected into three groups: FLACS, MICS (1.8mm) and SICS (2.6mm) group. Pre- and postoperative data were evaluated by swept source optical coherence tomography. Control examinations were performed preoperatively and on the first, seventh day, one and six months postoperatively. BCVA, CCT, central anterior and posterior astigmatism induction and peripheral posterior elevation of the cornea were analyzed. The endothelial cell density and its percentage lost were calculated.

Results:

There was no significant difference in central anterior and posterior astigmatism induction, but we observed significant change in peripheral posterior elevation assessed in the 120-degree meridian mean -129,5µm (FLACS group), -74 µm (MICS group), -125 µm (SICS group)  on the first postoperative day and on the seventh postoperative day mean -92,8 µm (FLACS), -56,6 µm (MICS), -94 µm (SICS). Corneal morphology analysis revealed no significant differences between groups in a transient peripheral corneal edema, local Descemet membrane detachment, corneal would leakage, microerosion and posterior corneal opacities. The endothelial cell lost of 9% (FLACS), 12,63% (MICS), 13% (SICS) was revealed.

Conclusions:

The endothelial cell lost was the lowest in FLACS group. The MICS group have the lowest impact on the posterior elevation map in the corneal incision meridian. Reduction in corneal size incision reduces the elevation of the posterior corneal surface. The optical coherence tomography is valuable devices allows to assessment the corneal morphology and topography changes after cataract surgery.
