Apr 1, 2022 · Subluxation. The lens can be subluxed, with either a haptic or an optic out of the bag. Both the anterior and posterior capsules may be intact, although there may be a defect or tear causing the IOL to dislocate into the anterior or posterior chamber.

The most common symptom of a dislocated IOL is a change in vision. The degree to which vision is affected will depend on the severity of the dislocation. This can appear as: 1. Blurring 2. Double vision 3. Seeing the edge of the lens implant IOL dislocation can also lead to other complications such as retinal detachment, bleeding, intraocular infla...
During most cataract surgery procedures, the IOL is placed inside the capsular bag, a sack-like structure in the eye that previously contained the cloudy lens. In some situations, this extremely thin capsular bag or the fibers that hold it in place rupture and the IOL support is compromised. Dislocation of the IOL can occur days to years after surg...
Your retina specialist will perform a detailed eye exam, including a careful examination of the peripheral retina. The dislocated IOL is sometimes photographed to document the extent of the problem. When a clear view of the retina cannot be obtained directly, an ultrasound of the eye can be helpful.
Based on the characteristics of the IOL dislocation, there are several different approaches to repairing this issue. In cases where the IOL dislocation is minimal and does not have a large impact on vision, your doctor may not recommend any treatment at all. When vision is affected and the patient is experiencing symptoms, surgery becomes necessary...
If there is a posterior capsule defect or tear, the IOL may slide out of the bag, hence out-of-the-bag dislocation. If there is a defect in the stability of the capsular bag support system e.g. zonular weakness, the entire IOL with the capsular bag may dislocate, hence in-the-bag dislocation.
Oct 14, 2018 · However, in some cases, the IOL can become dislocated to the point where a secondary intervention is required. In this article, expert surgeons share the techniques they use when faced with a dislocated lens.
Causes of dislocation. Early disloca tion may result from zonular weakness caused by iatrogenic surgical damage or trauma.
Nov 5, 2020 · Common Causes. “Dislocation is often due to progressive zonulysis, and certain conditions predispose to that eventuality, most typically pseudoexfoliation,” says Samuel Masket, MD, in practice in Los Angeles.
Oct 1, 2017 · Marfan syndrome, which is a systemic connective tissue disorder, is the most common congenital cause of crystalline lens dislocation. A mutation in the FBN1 gene renders the zonules weak and lax, leading to lens subluxation or dislocation, classically in the superotemporal direction.
