Posterior chamber intraocular lenses in a series of 75 autopsy eyes. Part II: Postimplantation loop configuration.
We illustrate, from the pathologist's viewpoint, the configuration of posterior chamber lens loops within the eye. The final configuration of these loops is often a "C" shape, particularly following capsular fixation. When one or both loops are placed in the ciliary sulcus, where tissue resistance to loop compressive forces is less than in the capsular sac, an invagination or erosion of the loop into the ciliary body stroma or ciliary muscle frequently occurs. Although a surgeon should first and foremost choose a lens design with which he or she is comfortable in terms of ease of implantation and good clinical results, our pathological observations indicate that a subtle compromise in loop configuration might provide a more physiologically correct configuration in the eye, particularly for those who prefer in-the-bag implantation. Most surgeons prefer a lens design that will provide adequate fixation in the ciliary sulcus if an attempted capsular sac implantation is not successful.
