Abstract Details


To compare clinical results of biaxial small-incision elliptical phacoemulsification and biaxial small-incision torsional phacoemulsification


Namik Kemal University, School of Medicine, Department of Ophthalmology, Tekirdag,


Medical records of 400 patients who underwent phacoemulfisication between April 2015 to June 2016 were retrospectively reviewed. Patients with nuclear grade IV cataract according to Lens Opacities Classification System III (LOCS III) and underwent biaxial small-incision torsional phacoemulfisication (group 1) and biaxial small-incision elliptical phacoemulfisication (group 2) were included this study. The main outcomes included corrected distance visual acuity (CDVA), central corneal thickness (CCT), central endothelial cell density (ECD), and clear corneal incision (CCI) morphology. Postoperative follow-up was at 1 day, 1 week, and 1 and 3 months.


Each group included 35 patients 35 (eyes). CDVA results in group 2 is better than group 1 at postoperative 1 week (P < .05). Third month after surgery, the mean CDVA for each group was 20/20 and the mean CCT turned back to the preoperative level (P = .70 and P = .31, respectively). Postoperative percentage of mean endothelial cell loss for groups was changing between 10.7 - 22.8%, but there was no statistically significant difference between groups (P > .05). Epithelial disclosure rate was higher in group 2 than group 1 at postoperative 1 day (P < .05).


This study shows that torsional and elliptical methods for biaxial small-incisional phacoemulsification is safe and have similar results for endothelial cell loss and morphological changes of corneal incision.
