Outcomes of paediatric cataract surgery with and without the use of trypan blue.

This systematic review was undertaken to answer the research question: "In children with primary cataracts, what are the outcomes (posterior continuous curvilinear capsulorhexis + posterior chamber intraocular lens implantation) of surgery when performed with and without trypan blue staining of the posterior lens capsule?" An electronic search in six biomedical databases was conducted to identify randomised controlled trials that compared trypan blue with no stain during surgery in children 0-16 years with primary cataracts. Titles and abstracts of studies published between 1946 and 2021 in English language were screened. Data extraction, risk of bias assessment and synthesis of findings were done by two independent reviewers, while conflicts were discussed and resolved with a third. A total of 115 of 153 articles were screened after de-duplication. Of these, 113 were excluded while 2 randomised controlled trials involving 56 eyes of 42 participants were included in the review. The risk of bias was similar across all domains in both. Staining of the capsule led to complete posterior capsulorhexis and optimal placement of the implant in >90% of study eyes, while the control arms had 65%-80% for both outcomes. Use of trypan blue in paediatric cataract surgery probably leads to better outcomes, but more well-conducted randomised controlled trials on this important topic are needed. © 2022 John Wiley & Sons Ltd.
