Clear Corneal Wound Size for EVO ICL Insertion
The clear corneal wound for EVO ICL insertion is approximately 3.0-3.2 mm, based on standard surgical technique for this procedure.
Wound Architecture and Characteristics
While the provided evidence does not contain specific FDA labeling or formal guidelines explicitly stating the exact incision size for EVO ICL insertion, the available research provides insight into the wound characteristics:
Main Surgical Incision (MSI) Details
The study examining wound architecture in ICL surgery 1 analyzed the main surgical incisions used for implantable collamer lens insertion and found:
- Mean incision length: 1146.70 ± 150.48 µm (approximately 1.15 mm in tunnel length)
- Mean incision angle: 42.83 ± 5.69 degrees
- Location: Typically performed in the temporal position
Clinical Context
The EVO ICL is designed to be inserted through a small clear corneal incision, which is one of the advantages of this phakic IOL platform. The incision must be:
- Large enough to accommodate the folded ICL during insertion (typically 3.0-3.2 mm external width)
- Self-sealing to avoid sutures
- Properly constructed to minimize induced astigmatism
The research demonstrates that these incisions show complete wound sealing and healing at 6 months postoperatively 1, with both main surgical incisions and opposite clear corneal incisions proving safe and effective.
Important Surgical Considerations
- The incision architecture plays a role in corneal astigmatism management
- Proper wound construction with adequate angle and length ensures self-sealing properties
- Temporal positioning of the main incision results in more angled and longer wounds with greater endothelial retraction compared to astigmatic incisions 1
Note: The exact external incision width (3.0-3.2 mm) is based on standard surgical practice for ICL insertion, as the lens must be folded and inserted through this opening, while the cited study measured the internal tunnel length rather than the external wound width.
