Implantable Collamer Lens (ICL)

Freedom from glasses starts here.

What is an implantable collamer lens?

An implantable collamer lens (ICL), also known as an implantable contact lens, is a vision correction lens implant that is implanted into the eye to correct short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. It functions exactly like a contact lens, except that it is surgically implanted into the eye. Unlike a contact lens, an ICL does not require any maintenance, and it cannot be seen or felt once implanted in the eye.

Am I a good candidate for an implantable collamer lens?

To be a suitable candidate, you should:

  • Be between 21 and 45 years old
  • Have a relatively stable prescription in the last year

Implantable collamer lenses (ICLs) are a good alternative for patients who are not suitable for LASIK or other refractive procedures. ICLs can correct a wide range of refractive errors and are therefore commonly recommended to patients with high prescriptions that cannot be safely treated with laser eye surgery.

ICLs can treat the following refractive errors:

  • Mild to severe myopia or short-sightedness (-0.50 to -20.0D)
  • Mild to severe hyperopia or long-sightedness (+0.50 to +10.0D)
  • Astigmatism (0.50 to 6.0D)

What is an implantable collamer lens made of?

Implantable collamer lenses are made of a proprietary material that contains a small amount of collagen which occurs naturally in your body, thereby making it biocompatible with the eye. The lens also contains an ultraviolet light filter to provide natural UV protection.

What are the benefits of an implantable collamer lens?

  • The procedure is reversible – while the ICL is intended to be permanently placed in your eye to correct your vision, one advantage of the lens is that it can be easily removed or replaced if necessary. For the majority of patients, the lens remains in the eye until it needs to be removed, usually at the time when a cataract develops, later in life.
  • The lens can be implanted with a quick, painless and minimally invasive procedure.
  • Vision recovery is very quick; you will be able to return to work after 1-2 days.
  • It is a safe and effective treatment for patients excluded from laser vision correction due to high prescriptions; thin, or abnormally shaped corneas; or severe dry eyes.
  • It treats a wide range of prescriptions.
  • The lens offers UV protection.

What does the surgery involve?

ICL surgery takes 20-30 minutes per eye and is performed under local anaesthetic.  A small opening is made in the periphery of the cornea to allow the ICL to be introduced into the eye through an injector. Once inside the eye, the lens unfolds and is positioned behind the iris. The small opening is self-sealing and does not require any sutures.

 

Visual recovery is fast and most patients are able to see very well by the next day. Your vision will continue to improve as the eye heals and settles down over the first few weeks following ICL surgery

Results You Can Expect With an Implantable Collamer Lens

ICL is designed to deliver strong visual outcomes in appropriate candidates, but it is important to set realistic expectations and understand long-term factors.PresbyMAX is one of several ways to manage presbyopia. The best option depends on your eyes, your goals, and how you feel about different trade-offs.

Visual Outcomes and Stability

The goal is sharp, stable vision with reduced dependence on glasses or contact lenses. Some people still choose to use glasses for specific tasks, but many achieve meaningful day-to-day freedom from corrective eyewear.

Night Vision and Halos

Some people notice halos or glare, particularly in dim lighting. This is assessed before surgery by looking at pupil size, prescription, and your visual needs. If night driving is a major part of your life, that should be discussed during planning so expectations are clear.

Long-Term Considerations

Even with excellent distance vision after ICL, vision can change with age. Many people will still need reading glasses later due to normal age-related focusing changes. Cataracts can also develop later in life because that is part of ageing. If cataracts develop, the ICL can be removed at the time of cataract surgery if required.

Why Choose City Eye Surgeons Clinic for ICL

Choosing the right setting for ICL is about careful assessment and a safety-first approach, not just the procedure day.

Comprehensive Suitability Screening

ICL is only recommended when measurements and eye health checks support a safe outcome. Screening includes anatomical safety checks, pressure risk assessment, and a close look at the retina when myopia is higher.

Surgeon Experience and Safety-First Planning

Lens selection, sizing accuracy, and surgical technique all matter. Your surgeon will explain why a particular plan is being recommended, what the main risks are for your eyes specifically, and how those risks are managed.

Ongoing Aftercare and Long-Term Monitoring

Follow-up is a core part of ICL care. Monitoring focuses on eye pressure, lens position, and long-term eye health so any changes can be managed early.

FAQs about Implantable Collamer Lens

Can ICL correct astigmatism?

The difference between ICL and LASIK is that ICL corrects vision by implanting a lens inside the eye while LASIK corrects vision by creating a corneal flap and reshaping corneal tissue with a laser.

Yes. Toric ICL options are designed to correct astigmatism, but careful measurement and alignment are important.

Do not drive on the day of surgery. You can drive again once your vision is safe and you have been cleared at follow-up. This timing varies between patients.
