Posterior Polar Cataract
Image Description
A young patient was referred to us for cataract surgery removal and artificial intraocular implant, due to progressive vision loss. Slit-lamp examination revealed posterior polar cataract. Posterior Polar cataract represents a medically and surgically unique subset of cataract that often arises at the end of a hyaloid artery remnant, which can result in a range of pathology from the benign "Mittendorf dot" to a more clinically relevant cataract [1]. Capsular fragility has been reported that is why surgical technique must place the least amount of stress possible on the posterior capsule [2]. The surgeon should avoid hydrodissection and the removal of the nucleus should be performed in a very stable anterior chamber. After lens material phacoemulsification, manual manipulation of posterior polar plaque should be attempted. If the posterior capsular rupture occurs, anterior vitrectomy should be done before placing the intraocular lens.
