Spontaneous Late Intraocular Lens and Capsule Tension Ring Dislocation

View Article: PubMed Central - PubMed

ABSTRACT

In this report, three cases with pseudoexfoliation (PEX) and advanced age with spontaneous intraocular lens (IOL) and capsule tension ring (CTR) dislocation were presented. All of our cases experienced progressive vision loss without an episode of strenuous physical activity, trauma, or any other ocular disease. Spontaneous dislocation was observed 2.5 to 8 years after uneventful phacosurgery. Each patient underwent complete IOL and CTR removal combined with anterior chamber IOL implantation. No complications were noticed during follow-up. As a result, capsule tension ring does not prevent late IOL dislocation after uncomplicated phacosurgery in the presence of PEX. Therefore, close follow-up is essential for patients with PEX.

f3: Intraocular lens and capsular tension ring folding in the fibrotic capsular bag

Mentions: A 79-year-old woman reported progressive visual blurring in the left eye for nearly 6 months. Her VA was counting fingers from 1 meter in the left eye and 20/20 in the fellow eye. According to her medical records, she had undergone uneventful phacoemulsification and one-piece foldable hydrophilic acrylic IOL implantation surgery in both eyes 8 years earlier. She was being medically treated for glaucoma in the right eye and had previously undergone trabeculectomy surgery on her left eye. Despite the absence of significant zonular weakness, CTRs had been implanted in both eyes for preventive purposes due to substantial accumulations of PEX material on both the pupillary margins and anterior capsular surfaces. Slit-lamp examination of the right eye showed bilateral pseudoexfoliation at the pupillary margin and stable IOL in the bag, whereas the left eye showed pronounced inferior dislocation of the IOL and CTR and total curving of the CTR inside the fibrotic and significantly constricted capsular bag. The patient underwent surgery to remove the subluxated capsular bag containing the IOL and CTR followed by anterior chamber IOL implantation (Figure 3). Her VA in the left eye was 6/10 at postoperative 1 month and there were no complications. Fundoscopic evaluation revealed cup-to-disc ratios of 6/10 and 8/10 and IOPs of 14 and 16 mmHg in the right eye and left eye, respectively.
