Trypan blue-assisted posterior capsulorhexis in pediatric cataract surgery.
OBJECTIVE
To evaluate the safety and efficacy of staining the posterior capsule with trypan blue during capsulorhexis in pediatric cataract surgery.


METHODS
This was a prospective randomized comparative study carried out at Alpha Vision Center, Zagazig, Egypt. This study included 2 groups of children with pediatric cataract randomly allocated to undergo irrigation and aspiration. In the trypan group, which included 11 eyes, trypan blue was used to stain the posterior capsule during posterior capsulorhexis. In the control group, which included 10 eyes, no staining was performed. All surgeries were performed by the same surgeon. The 2 groups were compared for criteria such as completion of capsulorhexis, disruption of vitreous face and in-the-bag intraocular lens implantation.


RESULTS
This study included 21 eyes of 16 patients (age range: 6 months-4 years). A statistically significant difference was observed for the following parameters between the 2 groups: capsulorhexis completion (P=0.04), vitreous face disruption (P=0.01) and in-the-bag intraocular lens implantation (P=0.022).


CONCLUSIONS
This study suggests that staining of the posterior capsule during capsulorhexis in pediatric cataract operation gives better results than capsulorhexis without staining. The stain changes the capsule texture making capsulorhexis easier with fewer complications.
