Abstract Details


The aim of the study was to compare the shape of the corneal incision, corneal edema and morphology of the corneal wound after 1.4 and 1.8 bimanual microincision cataract surgery .

107 eyes were classified to the study. All patients had cataract 3 - 5 grade in LOCS III scale. Patients were divided into 2 groups depending on the incision size. First group was Bi-MICS group with 1.4 mm incision. Second group was Bi-MICS group with 1.8 mm incision. Patients were examined one week, one month and 3 months after the operation. The structure of the incision, its thickness and tissue adhesion were evaluated by Topcon 3D OCT-2000.


Observing healing process of the cornea there were some differences between groups found. From baseline (1 week), central thickness of the main incision was smaller in 1.4mm group and such result remained till last follow up (3 months). Regarding to lateral and medial part of the incision, at baseline, cornea was thicker in 1.4 mm group, however, with the time the thickness was getting reduced and at last follow up was smaller in 1.4 mm group as well. Morphology of the incisions, higher percentage of endothelial gaping, misalignment of the edges or local thickening was observed in 1.8mm group


Decrease in deformation of the surgical wound is not only associated with surgical technique but mostly with better intraocular MICS lenses, adapted to the width of the surgical wound and better shape and different size of tools used for surgery. Both types of the incisions provide high grade of safety in postsurgical period. They are practically refractive neutral and they comply the rules of the postoperative infection prophylaxis.
