What is a Dislocated Intraocular Lens?
A dislocated lens occurs when the natural lens (dislocated crystalline lens) or intraocular lens implant (dislocated intraocular lens) falls from its normal position in the front of the eye backwards toward the retina. This can happen before, during, or after cataract surgery. Sometimes intraocular lens implants can dislocate spontaneously many months or years after successful cataract surgery.
Causes and Symptoms of a Dislocated Intraocular Lens
Some risk factors for development of a dislocated lens include:
- Cataracts/cataract surgery
- Ocular or facial trauma
- High myopia (nearsightedness)
- Pseudoexfoliation (PFX or PEX) — an age-related systemic syndrome that results in a flaky, dandruff-like material peeling off the outer layer of the lens of the eye that collects in the angle between the cornea and the iris, sometimes causing clogging in the drainage system of the eye and a build-up of eye pressure
- Retinitis pigmentosa
- Specific genetic conditions that lead to weakened lens support
Possible symptoms of a dislocated lens include:
- Painless blurring of vision in one eye
- Double vision
