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.
Insights
Microcoaxial phacoemulsification (MCP) safely reduces cataract surgery incision width. Further phacoemulsification parameter adjustments are needed for improved efficiency in this advanced cataract surgery technique.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Cataract Surgery
Background:
- Minimizing incision width is a key trend in modern cataract surgery.
- Microcoaxial phacoemulsification (MCP) represents a recent advancement in this area.
Purpose of the Study:
- To prospectively evaluate the surgical experience and outcomes of microcoaxial phacoemulsification (MCP).
Main Methods:
- 109 eyes with senile cataract underwent surgery.
- MCP group: 2.2 mm incision, hydrophobic intraocular lens.
- Comparison with a control group using 3.0 mm standard phacoemulsification.
Main Results:
- MCP allowed reduction in total surgical time with increasing experience.
- Excellent anterior chamber stability (89%) and wound closure (70%) were observed.
- Higher effective phacoemulsification time in MCP group (10.17s) vs. standard (4.98s).
Conclusions:
- MCP facilitates rapid and straightforward reduction of incision width in cataract surgery.
- While safety is maintained, efficiency improvements require phacoemulsification parameter optimization.
