To compare corneal topographic astigmatism change and endothelial cell loss induced by conventional coaxial, microcoaxial or biaxial microincisional phacoemulsification techniques.
: Department of Ophthalmology, Abant Izzet Baysal University Medical School, Bolu, Turkey
This prospective randomized clinical study included 73 eyes of 73 patients; 30 eyes were operated on through conventional coaxial, 26 eyes through microcoaxial and 17 eyes through biaxial phacoemulsification techniques. All patients received a four haptic hydrophobic acrylic intraocular lens (Acreos®, Baush & Lomb, USA) implantation at the end of surgery. Intraoperative effective phaco time was noted in all cases. Corneal topography, endothelial cell density and best-corrected visual acuity were measured preoperatively and 1, 7 and 30 days, and 3 and 6 months postoperatively.
There was no difference among the groups in terms of age, sex, corneal astigmatism, endothelial cell count and best corrected visual acuity, preoperatively. The intraoperative effective phaco time was not significantly different among the groups (p>0.05). Endothelial cell count was significantly less in conventional coaxial phacoemulsification group than the other groups on the postoperative day 7 (p=0.036). Mean steep and flat K values were similar in all visits among the groups (p>0.05 for all time points). Surgically induced astigmatism and best corrected visual acuity were not significantly different among the groups (p>0.05 for both).
All these techniques were found to be safe, effective and comparable in small incision cataract surgery in terms of surgically induced astigmatism and endothelial cell loss. FINANCIAL INTEREST: NONE
