Capsular hook-assisted implantation of modified capsular tension ring.

A 16-year-old boy presented with decrease of vision over a period of 2 years. On examination, he was diagnosed to have microspherophakia with lenticular myopia with secondary glaucoma in both eyes. He was treated by lens aspiration and two-point capsular support using a modified capsular tension ring (M-CTR) and capsular tension segment (CTS) sutured to the sclera along with implantation of a foldable intraocular lens inside the bag. Lens aspiration was performed without artificial capsular hook support of the bag, as the lens was soft and vitreous was formed. However, M-CTR rotation into the bag was fraught with repeated adherence of the advancing end of the M-CTR into the loose bag causing simultaneous rotation of the bag with the rotation of the ring resulting in transient increase in bag subluxation. Capsular hooks provided appropriate countertraction to the unsupported bag, thus facilitating easy insertion and rotation of the ring into the bag. 2016 BMJ Publishing Group Ltd.
