Abstract

Ectopialentis encompasses any displacement or mal-position of the crystalline lens irrespective of the cause or association. Lens subluxation can be congenital, acquired or due to developmental conditions, such as Marfan syndrome. The surgical management of ectopialentis is a challenging situation. The Ventura technique involves inserting an endocapsular tension ring and partly amputating one of the intraocular lens’ (IOL) haptics in order for the IOL’s optic to be centered in the visual axis after lens placement in the bag, without stressing the residual zonules. In the postoperative follow-up, minimal phacoiridodonesis is seen and the lens optic maintains centered in the visual axis. The use of the femtosecond laser associated with the Ventura technique facilitates the confection of the capsulotomy and enables the surgeon to decrease the residual astigmatism by making relaxing incisions.
