How the ICL Procedure Works
Preoperative Assessment: Before the surgery, the patient undergoes a comprehensive eye exam to assess eye health, the severity of refractive errors, and the suitability for an ICL. This includes:
- Measuring the thickness and curvature of the cornea.
- Evaluating the overall health of the eyes.
- Taking precise measurements of the eye’s size to determine the correct ICL power.
The Surgical Procedure:
- Anesthesia: The procedure is performed under local anesthesia, meaning the patient is awake but the eye is numbed using eye drops. Sedation can also be offered to help the patient relax.
- Incision: The surgeon makes a small incision, typically between 2.5mm to 3mm in size, at the edge of the cornea. This incision is tiny enough that it usually does not require stitches and will heal naturally.
- Lens Insertion: The surgeon folds the ICL and gently inserts it into the eye through the small incision. The lens is positioned in the posterior chamber, which is between the cornea and the natural lens, just in front of the iris (the colored part of the eye).
- Lens Placement: Once inserted, the ICL unfolds and is carefully placed behind the iris and in front of the natural lens, where it works to improve the focusing power of the eye.
- Closure: The incision is self-healing, and the lens remains permanently in place, providing refractive correction.
Postoperative Care: After the procedure, patients are typically sent home on the same day. The recovery process is relatively quick, but patients must follow the surgeon’s guidelines for recovery:
- Eye Drops: These are prescribed to reduce inflammation and prevent infection.
- Follow-up Visits: Several follow-up visits are scheduled to monitor the healing process and ensure the lens is positioned correctly.
Recovery Time: Most patients experience noticeable vision improvement within a few days. However, it may take a few weeks for the eye to fully adjust to the implant and for any residual swelling or discomfort to subside. Patients may experience mild irritation or blurred vision immediately after the procedure, but these symptoms generally resolve over time.
