Abstract Details

Purpose:

To compare surgically induced astigmatism (SIA) after bimanual 1.4 mm microincision cataract surgery (B-MICS) and coaxial 1.8 mm microincision cataract surgery (C-MICS).

Setting:

Department of Ophthalmology, Medical University of Lodz, Norbert Barlicki Memorial Teaching Hospital No. 1, Poland. Head: Wojciech Omulecki MD, PhD

Methods:

A total of 60 eyes of 60 consecutive patients were enrolled in this prospective, single-center study. The examined group consisted of 30 eyes of 30 patients who had uneventful B- MICS surgery through a 1.4 mm clear corneal microincision. The control group consisted of 30 eyes of 30 patients who had uneventful C- MICS surgery through a 1.8 mm clear corneal microincision. In all patients an aspheric Incise® IOL MJ14 (Bausch & Lomb, Rochester, N.Y., USA) intraocular lens was implanted. Examinations were performed preoperatively and 1, 7, 30, 90 days after the surgery.

Results:

In both groups there was a significant postoperative increase in mean BCVA. In vector analysis the difference in mean SIA between the groups was significant, which suggests that wound-assisted injection technique through 1.4 mm corneal microincision in bimanual phacoemulsification induces a higher value of SIA than 1.8 mm microincision in coaxial MICS.

Conclusions:

In our series of patients both techniques allowed to achieve exellent visual results. We found that amount of SIA induced by both techniques is small, however, according to used method of SIA analysis B-MICS induces a significantly higher value of SIA than C-MICS. Both MICS techniques were similar in terms of minor surgical trauma and the influence of surgery on corneal endothelial cell density and intraocular pressure.
