%X mparative analysis of corneal morphological changes after transversal and torsional phacoemulsification through 2.2 mm corneal incision Original Research (842) Total Article Views Authors: Assaf A, Roshdy MM Published Date January 2013 Volume 2013:7 Pages 55 - 61 DOI: http://dx.doi.org/10.2147/OPTH.S39019 Received: 10 October 2012 Accepted: 05 November 2012 Published: 08 January 2013 Ahmed Assaf, Maged Maher Roshdy Ophthalmology Department, Ain Shams University, Cairo, Egypt Purpose: This paper compares and evaluates the corneal morphological changes occurring after cataract surgery through a 2.2 mm corneal incision. We use two platforms for comparison and evaluation, transversal and torsional phacoemulsification. Patients and methods: This study includes 139 consecutive cataractous eyes (nuclear color 2¨C4, according to the Lens Opacities Classification System III [LOCSIII]) of 82 patients undergoing cataract surgery through a 2.2 mm corneal incision. Two different phacoemulsification platforms were used and assigned randomly: we used the WhiteStar Signature  system with the Ellips  FX transversal continuous ultrasound (US) mode for group I (mean age: 65.33 ¡À 6.97 years), and we used the Infiniti  system with the OZil  Intelligent Phaco (IP) torsional US mode for group II (mean age: 64.02 ¡À 7.55 years). The corneal endothelium and pachymetry were evaluated preoperatively and at 1 month postoperatively. Incision size changes were also evaluated. Results: All surgeries were uneventful. Before intraocular lens implantation, the mean incision size was 2.24 ¡À 0.06 mm in both groups (P = 0.75). In terms of corneal endothelial cell density, neither preoperative (I vs II: 2304.1 ¡À 122.5 cell/mm2 vs 2315.6 ¡À 83.1 cell/mm2, P = 0.80) nor postoperative (I vs II: 2264.1 ¡À 124.3 cell/mm2 vs 2270.3 ¡À 89.9 cell/mm2, P = 0.98) differences between the groups were statistically significant. The mean endothelial cell density loss was 1.7% ¡À 1.6% and 2.0% ¡À 1.4% in groups I and II, respectively. Furthermore, no significant differences between groups I and II were found preoperatively (P = 0.40) and postoperatively (P = 0.68) in central pachymetry. With surgery, the mean increase in central pachymetry was 28.1 ¡À 23.6 ¦Ìm and 24.0 ¡À 24.0 ¦Ìm in groups I and II, respectively (P = 0.1). Conclusion: Ellips  FX transversal and OZil  IP torsional phacoemulsification modes are safe for performing cataract surgery, inducing minimal corneal thickness and endothelial changes.
