Mr JM, a 63-year-old patient, presented to our practice with bilateral blindness from dense cataracts. His visual acuity was hand movements in both eyes, leaving him unable to mobilize independently or work to support his family. After waiting two years for surgery at a local hospital, he sought help at our practice—and we were privileged to assist. During surgery we encountered a classic intraoperative sign seen in intumescent white cataracts: the Argentinian Flag Sign. To perform cataract surgery safely, the anterior capsule is often stained with trypan blue to improve visualisation while creating a continuous curvilinear capsulorrhexis—a circular opening in the capsule that allows access to the lens material. In intumescent cataracts, the lens becomes pressurised by liquefied cortex trapped beneath the capsule. When the capsulorrhexis is initiated, the sudden decompression can cause the tear to extend rapidly toward the lens periphery on either side. The resulting pattern—a central white cataract bordered by two blue-stained capsular flaps—resembles the blue-white-blue stripes of the Argentinian flag . Recognizing this sign is critical because uncontrolled capsular extension can lead to: • Extension of the tear to the lens equator or posterior capsule • Risk of lens material dropping into the vitreous cavity requiring retinal surgery • The need to modify surgical technique or convert to a different surgical approach In this case, Dr Kashmira Rawjee used specialised techniques to safely decompress and remove the cataract without vitreous loss or capsular complications. An intraocular lens was successfully implanted in the capsular bag, and the capsulorrhexis was completed. The most rewarding moment came two days after surgery, when Mr JM was able to perform a simple but life-changing task again—walking independently. We look forward to his upcoming postoperative review to see the full visual and functional impact that cataract surgery will have on his life.
