Summary
A rare case of dislocated posterior chamber intraocular lens (IOL) after eye trauma highlights the importance of proper surgical technique. Meticulous capsular cleaning and large capsulotomy can prevent complications like zonular weakness and IOL luxation.
Area of Science:
- Ophthalmology
- Surgical Case Reports
Background:
- Posterior chamber intraocular lens (IOL) implantation is a common procedure.
- Complications such as IOL luxation can occur, though rare.
- Ocular contusion presents a risk factor for post-operative IOL displacement.
Observation:
- A 46-year-old male presented with IOL luxation within the capsular bag post-ocular contusion.
- Preoperative axial length measured 36.58 mm.
- Pars plana extraction of the dislocated IOL was successfully performed using forceps.
Findings:
- The trauma likely caused rupture of weakened zonules, attributed to capsular fibrosis.
- This case demonstrates a rare complication of IOL dislocation after ocular trauma.
Implications:
- Emphasizes the need for a large continuous curvilinear capsulotomy during cataract surgery.
- Highlights the importance of meticulous anterior and posterior capsule cleaning.
- Suggests these techniques minimize risks of postsurgical fibrosis and capsule contraction, preventing IOL instability.
