Titre	Incidence of rhegmatogenous retinal detachment after bag-in-the-lens intraocular lens implantation.
Abstract Nr.	1022

But	To determine the incidence of retinal detachment (RD) after phacoemulsification followed by bag-in-the-lens (BIL) intraocular lens (IOL) implantation. Moreover, this study is aimed at identifying risk factors associated with an increased risk of RD.
Méthodes	Using the database of the Antwerp University Hospital, we included BIL IOL implantations performed from January 1, 2001, through December 31, 2007. Combined procedures and IOL exchanges were excluded from this study. The incidence of RD as well as its associated risk factors was assessed. First, life tables were used to calculate the cumulative incidence of RD within 2 years after surgery. Then, Cox proportional hazards analysis was used to estimate the hazard ratio for each variable, taking into account each patient’s follow-up.
Résultats	BIL IOL implantation was performed in 1387 eyes. One year after surgery, 5 cases of RD were determined, accounting for an incidence of 0,49%. Within a 2-year follow-up period, 9 cases of RD were identified. Hence, the incidence of RD after BIL IOL implantation was 0,96% within a 2-year follow-up period. Cox proportional hazards analysis yielded 5 significant risk factors associated with RD: male sex, a history of eye trauma, axial length ≥ 25 mm, age < 60 years and finally a history of RD.
Conclusion	In our retrospective cohort study, the incidence of RD following BIL IOL implantation was 0,96% within a 2-year follow-up period. This result corresponds to the incidence of RD seen after conventional lens-in-the-bag (LIB) IOL implantation. Our study also identified 5 risk factors associated with the development of RD following BIL IOL implantation, namely male sex, a history of eye trauma, axial length ≥ 25 mm, age < 60 years and a history of RD.
