Severe capsulorhexis contracture after cataract surgery in myotonic dystrophy

A 42-year-old woman with myotonic dystrophy developed bilateral severe capsulorhexis contracture after uneventful phacoemulsification cataract surgery with implantation of 1-piece poly(methyl methacrylate) intraocular lenses (IOLs). The anterior capsular opening in her right eye constricted to a diameter of 0.7 mm, reducing visual acuity to counting fingers. Complete closure of the capsulorhexis with IOL encapsulation developed in her left eye, reducing visual acuity to hand movements. Surgical anterior capsulectomies restored visual acuity to 6/9 in both eyes. Myotonic dystrophy may predispose to the development of severe capsulorhexis contracture after cataract surgery.
