Biaxial microincision versus coaxial small-incision clear cornea cataract surgery.

摘要: Objective To compare clinical outcomes of biaxial microincision (1.5 mm) and coaxial small-incision (2.75 clear cornea cataract surgery. Design Randomized controlled trial. Participants Seventy eyes 70 patients were examined at a German university eye hospital. Intervention The (70 eyes) assigned randomly (1:1) to or conventional incision group. Both groups underwent phacoemulsification using pulsed ultrasound energy with variable duty cycles, followed by intraocular lens implantation. Main Outcome Measures Best-corrected visual acuity (BCVA), astigmatism, laser flare photometry value, effective time (EPT), endothelial cell count evaluated. Results treatment did not differ in baseline characteristics (median BCVA 20/40 preoperatively both groups, P = 0.97). On postoperative day 1, was better the group than (20/25 vs. 20/33, 0.018). Eight weeks after surgery, median BCVAs 20/20 20/25 ( 0.015). Median changes astigmatism −0.15 diopters (D) −0.31 D Neither clinically relevant nor statistically significant differences found values. Effective >3 seconds only 34% procedures, versus 68% procedures 0.013). At 8 counts decreased similarly (14.5%) (14.1%) 0.408). Conclusions With technique, EPT is shorter improves more rapidly, no difference results, relative technique for phacoemulsification.
