Intraocular lens dislocation occurs when the intraocular lens implanted during cataract surgery moves out of its intended position, causing blurred vision and a deterioration of vision. Conversely, lens dislocation refers to the displacement of the natural lens we inherit due to damage or weakening of the ciliary zonules.
Genetic conditions like Marfan syndrome or eye trauma can contribute to the occurrence of lens dislocation.
Classification and Symptoms
The causes of intraocular lens dislocation include pseudoexfoliation syndrome (a condition characterized by abnormal protein accumulation or deposition in the lens, iris, etc.), myopia, a history of intraocular surgery, eye trauma, etc., and symptoms may include blurred vision. However, this may vary depending on the degree of the intraocular lens dislocation.
Diagnosis
A simple slit lamp examination may detect and diagnose the dislocation of intraocular lens.
However, a more detailed diagnosis is usually made by dilating the pupil and observing it closely.
Treatment
The surgical treatment for intraocular lens dislocation depends on the degree of lens dislocation.
If the lens is not completely dislocated, a procedure called scleral fixation of the intraocular lens can be performed to restore the intraocular lens to its proper position by securing it to the sclera or iris.
However, in cases where the lens is fully dislocated and accompanied by other ocular conditions, complete removal of the intraocular lens is necessary, followed by the insertion of a new intraocular lens. In cases where the intraocular lens has extended beyond the retina or optic nerve, the retina is also covered by the surgery.

Retina & Glaucoma Clinic at The One Seoul Eye Clinic has extensive experience in performing surgery on patients referred for intraocular lens dislocation, fostering assurance in expecting effective results
Notably, we have gained attention through the publication of the paper "Safety Barricade Suture for Preventing Pupillary Capture of Intraocular Lens With Scleral Fixation: H-Technique (RETINA, 2016),
" significantly enhancing the success rate of scleral fixation of intraocular lenses using this surgical approach.
