Intraocular lens luxation or subluxation is an uncommon complication that can arise after cataract surgery. In this condition, the artificial intraocular lens that has been implanted in the eye shifts or moves from its original position, either partially (subluxation) or completely (luxation).

Risk Factors:

This condition is therefore associated with several risk factors, such as:

  • Ocular trauma: A blow or injury to the eye can increase the risk of dislocation of the intraocular lens.
  • Certain pre-existing eye problems: Conditions such as high myopia, glaucoma, or Marfan syndrome can predispose individuals to lens luxation or subluxation.
  • Defect in the intraocular lens: In rare cases, a manufacturing defect in the intraocular lens may lead to its displacement.
  • Complex cataract surgery: Cataract surgery in eyes with complex anatomy or complications during the procedure can increase the risk of lens luxation or subluxation.

Symptoms

The symptoms of intraocular lens luxation or subluxation can appear suddenly or gradually. They may include:

  • Decreased vision: Vision may become blurred or distorted, either in one eye or both.
  • Difficulty focusing: It may be challenging to focus on objects at any distance.
  • Double vision or diplopia: Double vision may occur in one or both eyes.
  • Light halos: There may be halos of light in the field of vision.
  • Eye pain: In some cases, there may be eye pain or a feeling of discomfort.

 

To make an accurate diagnosis, the ophthalmologist conducts a comprehensive eye examination. They will examine the position of the intraocular lens and may perform additional tests such as ocular ultrasound or optical coherence tomography (OCT) to obtain a more detailed image of the eye.
