BACKGROUND: The further reduction of the incision width is a recent development in cataract surgery. The purpose of this prospective clinical study was to evaluate the surgical experience with microcoaxial phacoemulsification (MCP).
PATIENTS AND METHODS: A total of 109 eyes with senile cataract were operated. 37 patients (37 eyes) received MCP with a 2.2 mm corneal incision width (Megatron S 3, Geuder) and implantation of a one-piece, hydrophobic intraocular lens (AcrySof, Alcon). The intraoperative parameters of total surgical time, effective phacoemulsification time, anterior chamber stability, and wound closure were compared to a control group of 72 patients with a 3.0 mm incision width and standard phacoemulsification.
RESULTS: Total surgical time with MCP could be reduced with increasing experience (p = 0.012). All procedures were without complications. The anterior chamber stability and wound closure at the end of the procedure were excellent in 89 % and 70 % of the cases, respectively. After intraocular lens implantation a stromal hydration of the wound was necessary in 11 % of the patients. The mean effective phacoemulsification time was, in the MCP group (10.17 +/- 5.53 seconds), higher than in the standard phacoemulsification group (4.98 +/- 3.11 seconds, p < 0.001).
CONCLUSIONS: Microcoaxial phacoemulsification allowed a rapid and easy reduction of the incision width in cataract surgery. Although the safety was ensured, further efficiency improvements with modification of the phacoemulsification parameters are necessary.
