Summary
Performing continuous circular capsulorhexis in mature cataracts is challenging. Injecting air into the anterior chamber improves visibility and facilitates safe handling of the anterior capsule during this crucial step in cataract surgery.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Continuous circular capsulorhexis is a standard technique in cataract surgery.
- Mature cataracts present challenges due to poor anterior capsule visibility.
Purpose of the Study:
- To describe a modified technique for performing capsulorhexis in mature cataracts.
- To improve visibility and safety during capsulorhexis in challenging cases.
Main Methods:
- Performing capsulorhexis under an air bubble in the anterior chamber.
- Using a high molecular weight viscoelastic agent to maintain the air bubble and prevent leakage.
Main Results:
- The air-filled anterior chamber significantly enhances visibility of the anterior capsule.
- The technique allows for easy and safe manipulation of the anterior capsule.
- Continuous circular capsulorhexis was successfully achieved even in mature cataracts.
Conclusions:
- Performing capsulorhexis under air is an effective method to overcome poor visibility in mature cataracts.
- This technique enhances safety and ease of handling during cataract surgery.
