The following article was received based on a literature review: assessment of intraoperative complications in intumescent cataract surgery using 2 ophthalmic viscosurgical devices and trypan blue staining.The publication reports 2 anterior capsule tear, one of the anterior tear radiated and caused posterior capsule rupture, same that resulted in vitreous loss.The procedure was converted to eec (extracapsular cataract extraction) with anterior vitrectomy and iol implantation at ciliary sulcus.In group 1 they used medium viscosity ophthalmic viscosurgical device (ovd) healon while in group 2 they used both medium viscosity and high viscosity healon.In group 1 there were capsule tears in 2 eyes and in 1 eye, the procedure was converted to eec (extracapsular cataract extraction) with anterior vitrectomy and iol implantation at ciliary sulcus.In group 2, there were no capsule tears.The study concluded that using 2 different ovds and placing the high-viscosity ovd centrally led to safe indentation of the anterior lens capsule and reduced the risk for continuous curvilinear capsulorhexis (ccc) enlargement and capsule tear during surgery.
