Phacodonesis

Phacodonesis: When the lens loses its stability

Phacodonesis is the medical term for the vibration of the lens inside the eye. This condition occurs as a result of the loss of stability of the lens and its improper fixation within the eyeball. Translated from Greek, “phaco” means “lens” and “donesis” means “oscillation.” Phacodonesis can be a consequence of various factors and have different clinical manifestations.

One of the main causes of phacodonesis is the removal of the lens during lens replacement surgery (phacoemulsification). In such cases, phacodonesis occurs due to loss of the suspensory ligaments that normally hold the lens in a stable position. The lens may begin to vibrate or move within the eye due to eye movements or changes in head posture.

The clinical manifestations of phacodonesis may vary depending on the degree of lens oscillation. Patients may complain of noticeable fluctuations in vision when moving the eyes or changing head position. In some cases, phacodonesis may be accompanied by additional symptoms, such as the sensation of floating spots in front of the eyes or decreased quality of vision.

Treatment of phacodonesis depends on its cause and clinical manifestations. In many cases, phacodonesis does not require special treatment and can regress on its own over time. However, if the symptoms of phacodonesis significantly affect the patient's quality of life, additional treatment may be required.

In some cases, additional medical tests, such as an ultrasound examination of the eye, may be necessary to assess the degree of lens wobble and identify any associated pathologies. In more severe cases of phacodonesis, where symptoms are persistent and significantly impair the quality of vision, surgery may be required to stabilize the lens or remove it.

In conclusion, phacodonesis is a condition in which the lens inside the eye loses its stability and begins to vibrate or move. This may be due to various factors, including surgical removal of the lens. If you have symptoms of phacodonesis, it is recommended to see your doctor for evaluation and determination of the most appropriate treatment.
