Purpose: To describe a new intraocular lens that can be implanted in case of rupture of the posterior capsule and lack of capsular support. Methods: This experimental study was carried out on ten Flanders rabbits. The right eye of each rabbit underwent intra capsular lens extraction and two peripheral iridectomies, and the new lens was implanted with an optic rest in the posterior chamber. Additionally, the haptics rest in the angle of the anterior chamber through peripheral iridectomies. Main outcome measures were lens stability inside the eye and complications regarding this technique. Results: Intraocular lenses remained in a stable position with only a mild inflammatory reaction; four eyes developed hyphema that disappeared 10 days after surgery. Conclusion: The new lens design has good intraocular stability when posterior capsular support is absent and only produced minimal inflammation inside the eye.
A 40-year-old male presented with visual impairment in the right eye (OD). He had undergone a pars plana vitrectomy for retinal detachment in the OD three years prior. Biomicroscopic examination revealed significant hyperemia, rubeosis iridis, anterior subluxation of the intraocular lens (IOL), and an organized hyphema located in the inferior third of the anterior chamber, characterized by the entrapment of iris tissue between the anterior synechia and the IOL.
