Phacoemulsification in Hard Brown Cataract

A hard brown cataract refers to a mature or advanced cataract that has a dense, brownish coloration and is difficult to remove during cataract surgery. Hard brown cataract may be difficult to break up into smaller fragments during the phacoemulsification process, as it requires more ultrasound energy. The elevated phaco energy and active time can damage the corneal endothelial cells and lead to corneal edema or even Pseudophakic Bullous Keratopathy. The zonules, or delicate fibers that hold the lens in place, may be more likely to break during the surgery in eyes with a hard brown cataract. This can lead to instability of the lens, and increased risk of complications such as posterior capsular tear.
