    Abstract:

    To observe the stability of silicone plate-haptic intraocular lenses implanted following cataract surgery and analyze the reasons related to decentration and dislocation into the posterior segment. · METHODS: We report 3 cases of posterior dislocation of silicone plate-haptic lenses (Bausch and Lomb C11UB and Chiron C11UB) in patients who underwent uneventful phacoemulsification. · RESULTS: One occurred 4 years following sectoral anterior capsulotomy for advanced anterior capsular contraction, the other in the early post-operative period following posterior capsulotomy and the third is a delayed (3 months), dislocation following uneventful posterior capsulotomy. None of the cases were associated with a history of trauma or other precipitating event. · CONCLUSION: Silicone plate haptic IOLs seem to be prone to dislocation due to poor capsular adherence as they are only held in place by the fibrotic fusion of the haptics. If either the posterior or anterior capsules are disrupted, the forces created by capsular contraction may cause extension of radial tears, with subsequent posterior dislocation of the implant. Though the use of silicone plate-haptic lenses has been surpassed by other models, there are patients who had implantation of such lenses that may undergo YAG laser capsulotomy. It is important to inform them about the potential risk of posterior dislocation as an early or late complication following this procedure.
