Implantable Collamer Lens (ICL) is a popular alternative for contact lenses and glasses. The doctors implant these lenses inside the eyes to correct the vision. The ICL is created from a biocompatible material known as collamer. The material is a combination of polymer and collagen that does not cause any discomfort to the patients.

For the user, the difference between the contact lens and ICL is that they don’t have to remove the ICL regularly like the contact lens as it is implanted inside the eye by surgery.

ICL is of two types:

  • ICL Toric : Along with the spherical vision problems, it also corrects the cylindrical power.
  • ICL Spherical : Corrects the spherical power.

Before ICL surgery, you have to go through a screening procedure to make sure your eyes are healthy and suitable for the implantation surgery. During the screening, the doctor will take your complete eye health and medical history. The doctor will also check your eyes thoroughly to measure your pupils, the distances between the iris and cornea (anterior chamber depth) and count the number of cells on the back of the cornea (endothelial cell counts).
