CataractCoach™ 2643: very young patient with white cataract

Performing cataract surgery on young patients with intumescent white cataracts presents a unique and formidable challenge for ophthalmic surgeons. Unlike age-related cataracts that often involve nuclear sclerosis and a firm lens, intumescent white cataracts are typically soft, swollen, and under significant intralenticular pressure due to the accumulation of liquefied cortical material. This is particularly true in younger patients, where the lens lacks the fibrotic rigidity of older, sclerotic nuclei. The high internal pressure can cause the anterior capsule to bulge forward, creating a convex configuration that increases the risk of uncontrolled radial extension of the capsulorhexis—a phenomenon often referred to as the “Argentinian flag sign.” Once the anterior capsule is punctured, the sudden decompression may result in a dramatic and rapid tear, compromising the integrity of the capsular bag and increasing the risk of posterior capsule rupture. Moreover, because the lens matter is soft and mobile, cortical cleanup is more difficult, especially if the capsulorhexis has extended or zonular support is compromised. Phacoemulsification in such cases is often unnecessary and instead replaced by aspiration techniques, but these must be approached with caution to avoid damaging the posterior capsule. Techniques to mitigate risk include capsule staining with trypan blue, needle decompression prior to initiating the capsulorhexis, and creation of a small initial flap to allow for gradual decompression. Ultimately, successful surgery in these cases requires careful planning, dexterity, and a deep understanding of lens biomechanics to minimize complications and ensure visual recovery.
