Abstract

Lens ectopy is a condition in which the natural crystalline lens is dislocated. The lens may be
completely dislocated out of the hyaloid fossa, float freely in the vitreous body, or be dislocated in the
anterior chamber of the eye or lie directly on the retina. If the lens stays within the space of the objective
and is minimally displaced, it is called a subluxated lens.
There are a few reasons that may cause lens ectopy, but it usually occurs after an eye trauma. Other possible
causes are systemic and ocular diseases.
The treatment of the patient depends on the etiology. If the dislocation of the lens occurs as a result of trauma,
it may cause other complications of the eye, such as glaucoma, refractive changes, destruction of the
retina, and blindness.
Etiology: Systemic and ocular diseases, as well as eye trauma, are the main causes of lens dislocation.
Traumatic lens ectopy is usually a result of direct injury to the eye, but it may also occur after a head
injury. This condition must be diagnosed as soon as possible to start treatment.
The diagnosis is based on the ophthalmic examination, which includes vision assessment, refractometry,
tonometry, and examination with a biomicroscope. The biomicroscope exam can reveal if the lens is totally
dislocated or minimally displaced (subluxated). The fundus is also examined because retinal ablation is
another possible cause of lens ectopy.
Patients with lens ectopy may experience symptoms such as epiphora, a feeling of a foreign body in the eye,
hyperemic conjunctiva, and pain. The treatment depends on the degree of lens dislocation and whether
there are complications.
If the lens is dislocated in the anterior chamber, the treatment includes surgically removing the lens and
replacing it with a new one.
Dislocated intraocular lens is a rare but serious complication in which the intraocular lens is dislocated from its
natural position in the eye.
Globally, lens dislocation occurs at a rate of 0.2% to 3%.
