Objective:
To demonstrate the management of a dislocated Akreos AO60 intraocular lens (IOL) that had been previously fixated with Prolene sutures.
Approach:
- Surgical Technique: The procedure involved vitrectomy, cutting remaining Prolene sutures, and using a soft-tip cannula to manipulate the dislocated lens. The lens was threaded through a keratome wound and re-fixated using a 4-point fixation technique.
- Suture Management: Meticulous planning and organization were emphasized to avoid tangling of sutures during the procedure.
- Lens Positioning: The lens was positioned approximately 3-3.5 mm back from the limbus to avoid iris chafing and ensure proper centration.
Key Findings:
- Four-point fixation provides excellent IOL stability and minimizes tilt.
- Avoiding overtightening of fixation sutures can improve lens positioning.
- A small amount of 'hang-back' in sutures may enhance lens stability.
Interpretation:
Limitations:
- The discussion noted a 14% redislocation rate in secondary lens techniques, indicating potential challenges in these procedures.
