[Capsulorhexis staining by trypan bleu in mature cataract surgery].
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.


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).


CONCLUSIONS
In mature cataracts, with no red fundus reflex, capsulorrhexis can be done by anterior capsule staining.
