[Secondary intraocular lens implantation]

In recent years, techniques for the secondary implantation of intraocular lenses have undergone significant further development. Despite the wide range of surgical indications, IOL dislocation and aphakia following complicated cataract surgery or other complicated intraocular procedures and trauma remain the most common reasons for secondary IOL implantation. In cases where it is not feasible to place the artificial lens in the capsular bag due to zonular weakness or insufficient stability of the capsular bag, the intraocular lens can be implanted in the anterior chamber or fixed in the ciliary sulcus, on the iris or on the sclera. The techniques differ not only in the anatomical structure of the fixation, but also in the type of intraocular lens and materials used. While some methods are technically easier and quicker to perform, the learning curve for other techniques is flatter and takes more time. The experienced ophthalmic surgeon should be familiar with several of these methods and be aware of the advantages, disadvantages and contraindications of the individual techniques in order to be able to choose the most suitable method based on the findings of the individual patient.
