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.

Mentions: A 72-year-old man presented with symptoms of marked reduction of vision 3 years after cataract surgery on his right eye. He had undergone cataract extraction with anterior chamber IOL implantation in his left eye at another hospital five years before the phacoemulsification surgery on his right eye. Bilateral PEX and phacodonesis in his right eye were noted in his preoperative medical records from our hospital. Therefore, during the uneventful phacoemulsification, one-piece hydrophilic acrylic foldable IOL and CTR implantation was performed. The patient was followed for 3 months, and his visual acuity (VA) was 6/10 and no complication was observed at his final examination. Three years after his uneventful right eye operation, the patient presented to our clinic with complaint of blurred vision early in the morning upon waking. Slit-lamp examination revealed subluxation of the IOL and CTR inside the fibrotic and contracted capsular bag. The subluxation was inferior and towards the posterior when the patient was in supine position. Intraocular pressures (IOP) were 14 and 16 mmHg for right eye and left eye respectively. Fundus examination revealed bilateral dry age-related macular degeneration. The IOL and CTR in the fibrotic capsular bag were extracted with IOL forceps in order to prevent luxation into the vitreous (Figure 1). After performing anterior vitrectomy and inducing miosis with intracameral 0.5 mL of 0.01% carbachol solution (Miostat®, Alcon, USA), a one-piece polymethyl methacrylate (PMMA) IOL was implanted into the anterior chamber. At final examination at postoperative 6 months, the patient’s VA in the right eye had improved to 6/10 and slit-lamp examination revealed the IOL was stable, in correct position with normal pupil shape and without any anterior chamber reaction.
