A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month.There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing,lens removal with intraocular lens implantation.Slit lamp examination revealed a corneal scar at 9’oclock,a large transilluminant iris cyst superotemporally and adherent to corneal endothelium.It was extended from angle of the pupil and obstructing the visual axis.The patient underwent excision of an iris cyst through superior limbal incision.Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma.Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule.Post operatively 7 days,vision improved to 6/7.5 without complication.There was no recurrence up to 1 year postoperation.Histopathological finding revealed a benign cyst mass lined by simple cuboidal to nonkeratinized stratified squamous epithelium.We had achieved a good surgical outcome with no complication to date for our case study.We advocate this modified surgical method to completely remove iris cyst.
