Abstract Details

Purpose:

To compare the efficacy and safety outcomes of bimanual microincision cataract surgery (B-MICS) versus 2.2-mm coaxial phacoemulsification (C-MICS).

Setting:

Mansoura Ophthalmology Center, Mansoura University, Mansoura, Egypt

Methods:

Prospective, randomized, observational, comparative case series comprised 60 cataractous eyes, were randomly selected to have phacoemulsification through 2.2-mm coaxial incision (group A), and bimanual MICS through 1.2-mm incision (group B) using Infiniti system with Alcon Ozil handpiece and all eyes were implanted using aspheric microincision intraocular lens. The main outcomes measures were ultrasound power, effective phacoemulsification time, the mean estimated fluid use, and total surgical time, postoperative best-corrected visual acuity (BCVA), surgically induced astigmatism (SIA), higher-order aberrations, endothelial cell loss (ECL), and central corneal thickness (CCT). Follow up was 1 day, 1 week, 1 month, and 3 months after surgery.

Results:

The Mean Total surgical time was significant higher in B-MICS 10.09min than Co-axial 7.6min (P<0.001). Mean Estimated fluid used higher in C-MICS 66.5ml than B-MICS 61.5ml (P<0.07). Mean Phaco time, Mean Phaco Power; Mean EPT & Mean US Time were higher in Group-A than Group-B. non-statistically significant differences, related to the best-corrected visual acuity (BCVA). The Mean ECL was statistically significant higher among group-A 221.2 cells compared to group-B 167.5 cells p<0.001. The mean CCT change was significantly greater in group-A than group-B, p< 0.01. The SIA was statistically significantly improved in B-MICS than C-MICS p<0.001.

Conclusions:

NS: The B-MICS and C-MICS phacoemulsification techniques are reliable, functional, effective, and yield good visual outcomes and low complication rates. B-MICS with the smallest incision utilizes lower phaco parameters during the surgery. B-MICS induces less astigmatism (SIA), less endothelial cell loss (ECL), less central corneal thickness (CCT) changes and provides an earlier visual rehabilitation.
