Context. Tenon’s cyst or conjunctival cyst formation is not uncommon late complication of traditional extracapsular cataract surgery; however, few reports are available in the literature. Aims. Large cystic swellings were clinically diagnosed as filtering blebs at the cataract incision site in two patients. The purpose of the case presentation is to discuss the factors leading to cyst formation, visual loss and cyst recurrence after its excision. Patients and Methods. Case 1. Sixty-one-year-old male patient presented with a bleb at superior limbal region in the right eye, two years after cataract surgery. Case 2. A giant bleb was found at the same region in the right eye of a 65-year-old male patient, eight years after cataract surgery. Results. Complete excision of the cyst was performed with conjunctival autograft in the first patient and followed up for two years. No recurrence of the cyst was observed. Internal wound gaping was seen on gonioscopy in the second patient. Conclusions. Unstable scleral tunnel could explain bleb formation in both the patients. Complete bleb excision with conjunctival auto-graft resulted in closure of the defect with no bleb recurrence during two-year follow-up. Over-filtration causing hypotonic maculopathy was the reason for decreased vision in the second case.
