About EVO Implantable Collamer Lens (ICL)

Approved by the Food and Drug Administration in 2022, EVO ICL is an implantable lens that corrects vision without the removal of any corneal tissue (as happens during LASIK and PRK surgery) or lens replacement. In fact, a permanent, implantable contact lens, the ICL is placed over the existing lens. In addition to treating common vision issues such as nearsightedness (myopia) and astigmatism (blurry or distorted vision), the implant increases day and night vision without the need for eyeglasses or contact lenses. The EVO ICL procedure offers patients the following benefits and advantages:

  • Fast recovery time.
  • Minimal to no haze, glare, and halos.
  • Minimal need for postoperative medications.
  • A safe and effective option for patients who are not good candidates for LASIK or PRK.
  • An option for patients with severe nearsightedness who cannot be treated with LASIK.
  • Offers the flexibility of removal unlike LASIK or PRK, which are permanent surgeries.
  • Since the implant is placed over your natural lens, it can offer UV protection similar to sunglasses.
  • Although the ICL is a foreign object being placed inside the eye, the implant material is made from collagen, which is highly biocompatible with the natural chemistry of the eyes.

What Happens During an ICL procedure?

  • Measuring your eye: The treatment during ICL surgery is based on measurements of a patient’s vision prescription. During your consultation, your ophthalmologist will perform a detailed eye exam, and mapping of the cornea, refraction, and lens calculations. These measurements will determine the power of the lens to be implanted. You have to stop wearing your contact lenses for at least two weeks prior to this appointment to ensure your eyes are in best condition for testing.
  • Delivering your personal treatment: After numbing the eyes with eye drops, the surgeon creates a tiny incision in the eye. The EVO ICL is placed on top of your natural lens and fastened into position.

What to Expect After ICL Surgery?

The recovery after ICL surgery is simple and includes these steps:

  • The small incision will heal completely over time, usually one to two weeks.
  • Most patients can resume regular activity within a few days after the procedure.
  • There is minimal discomfort during an overnight recovery period.
  • Short postoperative drop treatment period.
  • Since ICL surgery does not change the anatomy of the eye or remove any cornea tissues, the implant can be removed or replaced if needed.
