Implantable Collamer Lenses

Implantable Collamer Lenses (ICL): An Alternative to Laser Vision Correction

Implantable Collamer Lenses (ICL) are an alternative to laser vision correction procedures like LASIK and PRK for individuals with moderate to high myopia (nearsightedness). Unlike LASIK and PRK, which permanently reshape the cornea, ICLs are surgically implanted inside the eye in front of the natural lens to correct refractive errors.

How ICLs Work

ICLs are made of a flexible, biocompatible material called Collamer, which contains a small amount of collagen. During the procedure:

  1. The surgeon creates a small opening in the eye to insert the rolled-up ICL.
  2. The ICL is positioned in front of the iris and behind the cornea, in the space between the iris and the natural lens.
  3. The ICL corrects vision by acting as an additional lens, bending light to focus it properly on the retina.

Benefits of ICLs

  1. Suitable for a Wide Range of Prescriptions: ICLs can correct a wide range of myopia, from -3 to -20 diopters, making them an option for individuals with moderate to high nearsightedness who may not be candidates for LASIK or PRK.
  2. Reversible: Unlike laser vision correction, ICLs are removable if needed, allowing for potential adjustments or removal in the future.
  3. Minimal Corneal Tissue Removal: ICL implantation does not involve removing corneal tissue, preserving the structural integrity of the eye.
  4. Excellent Visual Outcomes: Many patients achieve 20/20 vision or better after ICL implantation, with a high rate of patient satisfaction.

Candidacy for ICLs

Ideal candidates for ICLs are individuals with:

  • Moderate to high myopia (up to -20 diopters)
  • Stable vision for at least one year
  • Adequate corneal thickness and anterior chamber depth
  • No history of eye diseases or infections

It’s important to note that ICLs are not suitable for individuals with cataracts, glaucoma, or other eye conditions that may affect the outcome of the procedure.

Potential Risks and Complications

As with any surgical procedure, ICL implantation carries some risks, including:

  • Infection
  • Inflammation
  • Increased eye pressure (glaucoma)
  • Cataract formation
  • Corneal swelling or scarring
  • Retinal detachment
