Introduction of longstanding complicated sulcus intraocular lens into the intact capsular bag

Abstract

AIM: To propose a surgical technique that successfully reopened the empty and intact capsular bag after long periods of closure, with repositioning of the intraocular lens (IOL) from the ciliary sulcus into its preferred habitat inside the capsular bag. METHODS: This is a case series, prospective, and interventional study. The technique was first performed on an aphakic high myope with a closed posterior capsule for 18y. Afterwards, five patients with recurrently displaced sulcus IOLs for a range of 1mo to 7y were performed for the same technique. During surgery, identifying a “telltale white line” was an important landmark for detecting the site of major adhesions between the edge of the capsulorhexis and the posterior capsule. These adhesions were freed using combined manual and viscoelastic dissection, followed by an easier freeing of adhesions along the whole capsular bag. The IOL was safely implanted, exchanged, or introduced from the sulcus into the fibrotic and closed capsular bag. Patients were followed up for a period ranging from 6 to 17mo postoperatively. RESULTS: All the patients experienced a remarkable improvement in their subjective refraction. Slit lamp examination showed a postoperative centralized IOL in the bag. The follow up visits confirmed visual and IOL stability. CONCLUSION: This newly-introduced surgical technique facilitates the reopening of the empty yet intact capsular bag that has been closed by fibrotic proliferations, with secured implantation of the IOL inside the capsular bag. Patients with inadvertent implantation of IOLs into the ciliary sulcus, yet having an intact capsular bag, can benefit from this technique.
