title: Capsular block syndrome associated with horizontal jerk nystagmus.
abstract: A 78-year-old cataract patient with horizontal jerk nystagmus had phacoemulsification and intraocular lens (IOL) implantation in the capsular bag with continuous curvilinear capsulorhexis. One week postoperatively, the posterior capsule ballooned posteriorly, the anterior capsule opening was sealed to the IOL optic, and a transparent liquefied substance accumulated between the lens optic and the posterior capsule. The best corrected visual acuity was 0.6 with a myopic shift compared with the refraction after the first day. A neodymium:YAG laser posterior capsulotomy was performed, and the capsular block syndrome (CBS) resolved. The results confirm the experimental model proposed by Zacharias suggesting that saccadic eye movements contribute to CBS under certain anatomic conditions.
