Capsule Contraction Syndrome with a Microincision Foldable Hydrophilic Acrylic Intraocular Lens: Two Case Reports and Review of the Literature

Here we present 2 cases of capsule contraction syndrome (CCS). In both cases, a hydrophilic acrylic Akreos MI60 (Bausch and Lomb) intraocular lens (IOL) was implanted in the capsular bag through microincision cataract surgery, and the literature on the subject is reviewed. Since CCS has been described after the implantation of every IOL type, it is unlikely that the Akreos MI60 chemical and physical properties may cause CCS. When CCS occurs with IOLs composed of increasingly flexible materials that are inserted through incisions of decreasing size, a severe dislocation and deformation of IOL optics and haptics may develop. In both cases illustrated here, Nd:YAG laser anterior capsulotomy was highly effective. Hence, also based on the literature, which reports severe complications as a result of surgical intervention, it is suggested that Nd:YAG laser anterior capsulotomy be the first line of CCS treatment when the luxation of an IOL capsular bag is absent.
