Introduction: Although an IOL should be implanted into the posterior chamber there are situations especially after complicated retinal surgery when fixation of IOL into capsular bag or sulcus is not possible. In those cases a scleral fixation or an implantation into the anterior chamber is practicable. We present our experience with implantation of foldable IOL`s (Acry Sof) into the anterior chamber.
Method: In 15 PVR detachment patients with silicone oil where the own lens or posterior chamber lens with complete capsule had to be removed previously, we implanted a foldable IOL by clear corneal incision after oil removal. (Video) In 7 patients the Acry Sof has been implanted into the anterior chamber after complicated cataract surgery and lost capsular bag (f. e. zonulolysis in Pex).
Results: In all cases the IOL could be centered easily without any trauma to iris and chamber angle.Postoperative visual acuity was CF to 6/12 depending on retinal status. Maximal follow up time was 6 months. One foldable lens had to be removed as retinal redetachment in PVR occurred. We did not observe any IOP raise, anterior chamber bleedings or pupillary changes due to the IOL.
Conclusions: Due to the small incision, the soft material and the spontaneous way of centration we think a foldable lens as Acry Sof is technically easier to implant and probably less traumatous as the classical type of PMMA anterior chamber lens. Long term follow up has to prove our good postoperative results.
