We describe herein 3 cases that were referred by 3 experienced cataract surgeons within a 2-week period for plate haptic silicone lenses that had dislocated posteriorly into the vitreous cavity. In 2 of these cases the dislocation followed Nd:YAG laser treatments for angle-closure attack and capsular contraction syndrome, respectively. The third case occurred in an eye with a "notch" noted in the anterior capsulorhexis at the end of surgery.

Report of Cases. 

Case 1.  An 84-year-old white man underwent an uncomplicated phacoemulsification with placement of a Staar silicone plate haptic lens (Staar Surgical, Monrovia, Calif) through a 6-mm, continuous tear, anterior capsulorhexis. Progressive anterior capsular fibrosis with contracture occurred following surgery, causing decreased visual acuity with metamorphopsia believed to be secondary to posterior displacement and buckling of the optic. Five months postoperatively, the patient underwent Nd:YAG laser relaxation of the anterior capsule at the 6- and 12-o'clock positions. The capsulorhexis,
