Combined pars plana and limbal approach for removal of congenital cataracts

摘要

We describe a combined pars plana-limbal approach using a 25-gauge transconjunctival sutureless vitrectomy system for removal of congenital cataracts in a 5-month-old boy. The operated eye had anterior capsulotomy, lensectomy, posterior capsulotomy, and anterior vitrectomy through a pars plana transconjunctival incision created with a 25-gauge trocar. A limbal port incision was used to introduce an infusion micro cannula to maintain the anterior chamber. Incisions did not require suture closure. Following the procedure, inflammation was mild, the pupil was circular and centric, and the intraocular pressure (IOP) was stable. The eyes were left aphakic, and vision was corrected with spectacles. Amblyopia treatment ensued. This surgical technique appears to be safe and effective for the removal of congenital cataracts. Advantages include a more precise capsulotomy and more sufficient lensectomy and anterior vitrectomy, stable intraoperative IOP, and reduced surgical trauma and inflammation.
