Summary
Anterior capsule staining with trypan blue facilitates safe capsulorrhexis during cataract surgery when the red fundus reflex is absent. This technique aids in performing phacoemulsification and intraocular lens implantation, even in mature cataracts.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Cataract Surgery
Background:
- Performing capsulorrhexis can be challenging without a visible red fundus reflex.
- Anterior capsule staining offers a solution for improved visibility during cataract surgery.
Purpose of the Study:
- To evaluate the safety and efficacy of trypan blue staining for anterior capsule visualization during cataract surgery.
- To assess the feasibility of performing capsulorrhexis and phacoemulsification in mature cataracts with absent red reflex.
Main Methods:
- Twenty patients with mature cataracts underwent surgery after trypan blue injection into the anterior chamber.
- The study focused on the ability to perform capsulorrhexis and subsequent phacoemulsification.
Main Results:
- Successful circular capsulorrhexis was achieved in all twenty patients.
- Phacoemulsification and in-the-bag intraocular lens implantation were performed without operative complications.
- No residual coloration or post-operative complications were observed during follow-up (2-12 months).
Conclusions:
- Anterior capsule staining with trypan blue is a safe and effective method for performing capsulorrhexis in mature cataracts lacking a red fundus reflex.
- This technique enhances surgical safety and allows for successful cataract extraction and lens implantation.
