Safe positioning of an intraocular lens (IOL) after lentectomy in hereditary ectopia lentis has been achieved by various techniques including iris fixation by clipping or suturing, anterior chamber IOL with chamber-angle support and transscleral suturing of a posterior chamber IOL. None of these approaches requires preservation of the capsular bag, and they are regularly combined with an anterior vitrectomy. However, the loss of separation between the anterior and posterior compartment of the eye may make a key contribution to subsequent complications such as retinal detachment, macular oedema or even glaucoma. From an anatomical point of view, the surgical approach proposed by Cionni et al1 2 and now studied by Bahar et al3 See pages 1477, …
