What Is an Implantable Collamer Lens (ICL) Surgery?
Implantable Collamer Lens (ICL) Surgery is a procedure designed to correct poor eyesight caused by refractive errors by placing a Collamer lens inside your eye. This option is ideal for people who may not be suitable candidates for LASIK surgery. The recommended ICL surgery age limit, usually between 18 to 45 years.
The Collamer lens is made from a combination of collagen and a soft plastic material, making it lightweight, flexible and more natural for your eye. Its design allows oxygen and nutrients to pass through more easily than some other types of lenses, supporting overall eye health.
During the surgery, your ophthalmologist positions the lens behind your iris and in front of your natural lens to improve vision. Earlier versions of ICL required a small procedure called laser iridotomy, where one or two tiny holes were made in the iris. These holes helped prevent pressure build-up by allowing the eye's fluid to drain properly during lens implantation.
The latest EVO ICL lens has a tiny central hole built into it, eliminating the need for laser iridotomy. This hole allows eye fluids to flow naturally, making the procedure simpler and more comfortable.
Types of Implantable Collamer Lenses (ICL)
There are different types of ICLs designed to correct various vision problems. Choosing the right type depends on your eye condition and your surgeon's recommendation.
- Standard ICL: This traditional lens is placed behind the iris and in front of your natural lens to correct nearsightedness and certain refractive errors.
- Toric ICL: Designed for people with astigmatism, this lens corrects both nearsightedness and irregular corneal shapes, improving overall vision clarity.
- EVO ICL: The EVO lens includes a small central hole, allowing natural fluid flow inside the eye. This eliminates the need for additional procedures like laser iridotomy.
Each type of ICL is designed to provide safe, long-lasting vision improvement, with your surgeon helping you choose the lens that best fits your eyes and lifestyle. The proven ICL surgery success rate makes it one of the most reliable options for vision correction today.

When are Implantable Collamer Lenses Recommended?
Implantable Collamer Lens (ICL) surgery is considered for people who want a reliable solution for vision correction and may not be ideal candidates for LASIK. Here are the main situations where ICLs are recommended:
- High Nearsightedness (Myopia): If glasses or contact lenses are insufficient or uncomfortable, ICLs can effectively correct moderate to severe nearsightedness and improve daily vision.
- Astigmatism: For those with irregular corneal shapes causing blurred or distorted vision, Toric ICLs can correct both nearsightedness and astigmatism, offering sharper vision.
- Thin or Irregular Corneas: People with corneas that are too thin for LASIK or have irregular shapes can benefit from ICL surgery, as it doesn't involve reshaping the cornea.
- Lifestyle or Occupational Needs: For individuals who cannot wear contact lenses comfortably or need stable, high-quality vision for work or sports, ICLs provide a long-term solution.
- Desire for Reversible Vision Correction: Unlike some procedures, ICLs can be removed or replaced if needed, offering flexibility for changing vision needs over time.
ICL surgery is tailored to each patient's eye health, lifestyle, and vision goals, ensuring a safe and effective approach to clearer vision. Your ophthalmology doctor will also evaluate potential ICL surgery side effects, which are generally rare and temporary.
Preparing for Implantable Collamer Lenses Surgery Procedure
Proper preparation is essential for a smooth ICL surgery and quick visual recovery. Here's how you can get ready:
Medical Evaluation & Pre-Op Assessment
- Share your full medical history, current medications, and any eye conditions with your ophthalmologist.
- Undergo routine eye tests, including corneal measurements, eye pressure checks and retinal evaluation, to ensure suitability for ICL surgery.
- Bring all test results to your pre-operative appointment so your surgeon can finalize the procedure plan.
Health Habits & Lifestyle Adjustments
- Avoid smoking for at least 2-4 weeks before surgery, as it can slow healing and increase the risk of complications.
- Limit alcohol consumption and discuss with your doctor whether to pause medications that may affect bleeding or healing.
- Maintain a balanced diet rich in vitamins and minerals to support eye health and overall recovery.
Home & Support Preparations
- Arrange for someone to accompany you to and from the hospital on the day of surgery.
- Set up a comfortable space at home with essentials like eye drops, a clean towel, sunglasses, and a relaxing chair or recliner.
- Stock up on light snacks and water to stay hydrated after the procedure.
Day Before & Day of Surgery
- Follow your surgeon's instructions regarding fasting, typically avoiding food or drink for a few hours before surgery if sedation is used.
- Wash your face and eyelids gently; avoid makeup, creams, perfumes, or contact lenses on the day of surgery.
- Wear comfortable, loose clothing and leave jewellery or accessories at home.
By following these steps, you can help ensure your ICL surgery goes smoothly and your recovery is safe and comfortable.
What Happens During Implantable Collamer Lenses Surgery?
Implantable Collamer Lens (ICL) Surgery is a safe and effective procedure to correct vision problems like nearsightedness and astigmatism. It involves placing a thin, flexible lens inside the eye to improve clarity without removing corneal tissue.
- Preparation & Anesthesia: On the day of surgery, you'll meet your eye care team to review the procedure and address any questions. Local anesthesia with mild sedation is administered to keep you comfortable and relaxed throughout the surgery.
- Lens Placement: Your surgeon makes a tiny incision at the edge of the cornea. Through this opening, the Collamer lens is carefully folded and inserted into the eye. The lens is positioned behind the iris and in front of your natural lens for optimal vision correction.
- Lens Adjustment & Verification: Once in place, the lens is gently adjusted to ensure proper alignment and focus. Your surgeon checks that it sits correctly and allows normal fluid flow inside the eye, especially if using the EVO ICL with the central hole.
- Closing the Incision: The small corneal incision is self-sealing in most cases and does not require stitches. Protective eye shields or drops may be applied to support healing and prevent infection.
- Post-Surgery Care: After the procedure, you'll rest in a recovery area for a short period. You may be given eye drops to reduce inflammation and prevent infection. Most patients notice immediate improvement in vision, with full stabilization over the next few weeks.
Who Will Perform the ICL Eye Surgery Procedure?
ICL (Implantable Collamer Lens) surgery is a specialized procedure that is typically performed by experienced ophthalmologists or eye surgeons who have expertise in refractive surgery and intraocular lens implantation. These professionals are well-trained in performing various eye surgeries and are familiar with the intricacies of ICL surgery.
- Ophthalmologists: Ophthalmologists are medical doctors who specialize in eye care and surgery. Some of them are trained to do ICL surgery as part of their expertise in treating vision problems.
- Refractive Surgeons: These are ophthalmologists who focus specifically on vision correction surgeries, like LASIK or ICL. They are skilled in choosing the right treatment for your eye condition.
- Cornea Specialists: These eye doctors have deep knowledge of the cornea (the front part of your eye). Since ICL surgery is closely related to the cornea's health, their expertise is often valuable.
- Cataract Surgeons: Because ICL surgery is similar to placing a lens in cataract surgery, cataract surgeons may also be trained to perform ICL procedures.
