A 46-year-old woman with moderate lens subluxation and Marfan¿s syndrome underwent a phacoemulsification on the right eye with a sutureless Henderson Capsular Tension Ring (HCTR) implantation. The surgical procedure and the postoperative follow up period were uneventful, with a best corrected visual acuity (BCVA) of 0 (LogMAR). Seven months after surgery the patient presented an inferomedial displacement of the HCTR due to contraction of the capsular bag, displacing the ring over the inferior haptic of the IOL that was pulled posteriorly beneath the equatorial area but remained centered. No further treatment was prescribed. The HCTR did not maintain an adequate capsular bag expansion and failed to redistribute tension from non-affected zonules over the areas of zonulysis. This case report raises the hypothesis that modified CTR¿s stiffness should be evaluated as an independent factor in the selection of a proper device for each patient.
