[Capsulorhexis staining by trypan bleu in mature cataract surgery]
1Service d'Ophtalmologie, CHI Villeneuve Saint Georges, 94190, France.
Background:
Capsulorrhexis may be hazardous in the absence of the red fundus reflex. Anterior capsule trypan blue staining enabled to perform the capsulorrhexis and safe phacoemulsification.
Material And Methods:
Twenty patients with mature cataract were enrolled in the study and opereted on after injection of trypan blue in the anterior chamber.
Results:
Circular capsulorrhexis was performed in all cases followed by phacoemulsification and in-the-bag IOL implantation. In two cases hard nuclei required a manual extracapsular technique. No operative complications, and no residual of coloration was noted the day after the operation. With a follow-up of 2 to 12 months, no complications appeared (cornea, capsulorrhexis, IOP).
Conclusion:
In mature cataracts, with no red fundus reflex, capsulorrhexis can be done by anterior capsule staining.
