Management of posterior lenticonus complicated by unilateral cataract.
We studied 21 patients with 23 eyes with posterior lenticonus. Twenty-one of the eyes developed progressive cataractous changes that required lens aspiration in 19 eyes when vision reduction was 6/30 (20/100) or less. The inherent weakness of the diaphanous portion of the posterior lens capsule contributed to disruption of the normal lamellar arrangement of the lens fibers resulting in cataractous changes. Amblyopia was the most significant visual problem associated with posterior lenticonus. Fifteen of the 19 operated eyes in this study were amblyopic and nine of the 15 were improved to 6/15 (20/50) or better vision with occlusion therapy, after surgical aspiration of the cataractous lens and contact lens therapy.
