Summary
This study evaluated challenges in phacoemulsification for white mature cataracts. A two-stage continuous curvilinear capsulorhexis (CCC) technique achieved high success rates, even with increased intracapsular pressure.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- White mature cataracts present unique intraoperative challenges during phacoemulsification.
- Achieving a continuous curvilinear capsulorhexis (CCC) is crucial for successful cataract surgery outcomes.
Purpose of the Study:
- To assess intraoperative difficulties in phacoemulsification of white mature cataracts.
- To develop a reliable strategy for creating a CCC in these challenging cases.
Main Methods:
- Prospective study of 60 patients with senile white mature cataracts.
- Detailed intraoperative assessment of intracapsular pressure and cataract hardness.
- A two-stage capsulorhexis technique using a cystotome and forceps was employed.
Main Results:
- Continuous curvilinear capsulorhexis (CCC) was achieved in 95% of cases.
- Raised intracapsular pressure was a significant factor affecting CCC achievement (88% success in these cases).
- 50% of nuclei were grade 5 hardness; 33% showed capsule opacification.
Conclusions:
- Successful CCC creation leads to outcomes comparable to routine cataract surgery for white cataracts.
- The two-stage technique requires preparedness for managing hard cataracts through a small capsulorhexis.
