Management of Absent Capsular Support With A New Intraocular Lens Design - Management of Absent Capsular Support With A New Intraocular Lens Design - Open Access Pub

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.

The current available options are as follows: 1) Implantation of a scleral fixation intraocular lens (IOL) which is relatively a difficult technique. Complications include the possibility of decentration, infection through the suture track and late dislocation after trauma or suture lysis. 1,2 2) Implantation of an anterior chamber IOL although it is an easy technique, however possible endothelial decompensation is a late serious complication. 3 3) Implantation of an iris claw lens which need initially a learning curve. Known complications include problems related to pigment dispersion
