Implantable Collamer Lens (ICL) surgery is a vision correction procedure that offers an alternative to LASIK and other refractive surgeries. While it provides several advantages, it is essential to consider the disadvantages of ICL surgery before making a decision. Understanding potential risks, limitations, and long-term effects can help individuals determine if this procedure is suitable for them.
ICL surgery is particularly appealing for individuals who may not be candidates for laser eye surgeries due to thin corneas or high prescriptions. However, as with any medical procedure, there are important considerations regarding safety, effectiveness, and long-term maintenance. This article provides an in-depth analysis of the drawbacks of ICL surgery to help prospective patients make an informed choice.
What is ICL surgery?
ICL surgery involves implanting a biocompatible lens inside the eye to correct vision problems such as myopia and astigmatism. Unlike LASIK, which reshapes the cornea, ICL surgery does not remove any corneal tissue. This procedure is often recommended for individuals with thin corneas or those who are not suitable candidates for laser vision correction.
The lens used in ICL surgery is made of a material called Collamer, which is flexible and designed to be compatible with the eye’s natural structure. It is implanted behind the iris and in front of the eye’s natural lens, allowing for clear vision correction without altering the shape of the cornea. Since the ICL is placed inside the eye, it does not dry out like contact lenses and requires less maintenance. However, this does not mean the procedure is risk-free.
How ICL surgery works
During the procedure, a surgeon makes a small incision in the cornea and inserts the lens between the iris and the natural lens. The ICL remains in place permanently, enhancing visual clarity without the need for glasses or contact lenses. Although the lens can be removed if necessary, the procedure is generally considered a long-term solution.
Before the surgery, patients undergo a thorough eye examination to assess their suitability for the procedure. Measurements of the eye are taken to determine the appropriate lens size. The surgery itself is relatively quick, usually lasting around 15 to 30 minutes per eye. Local anaesthesia, typically in the form of eye drops, is used to numb the eye and minimise discomfort.
Following the procedure, patients are required to rest and avoid activities that could strain the eyes. Vision improvement is often immediate, but it can take a few days for the eyes to adjust fully. Regular follow-up appointments are necessary to ensure proper healing and monitor for any complications.
ICL surgery pros and cons
Like any medical procedure, ICL surgery has both advantages and disadvantages. While the benefits of ICL surgery include improved vision and suitability for patients with high prescriptions, potential drawbacks should also be carefully evaluated.
Some of the commonly mentioned benefits of ICL surgery include:
- Suitability for a wide range of prescriptions– ICL surgery can correct high levels of myopia that LASIK may not be able to treat effectively.
- Preserves the cornea– Unlike LASIK, which involves reshaping the cornea, ICL surgery leaves the corneal tissue intact.
- Reversibility– The implanted lens can be removed or replaced if necessary, providing flexibility for future vision correction.
- UV Protection– The Collamer material in the ICL provides additional protection against UV rays, reducing potential damage from sun exposure.
However, there are also significant drawbacks that should be considered before opting for ICL surgery.
Common disadvantages
- Cost: ICL surgery is more expensive than LASIK and other refractive procedures, making it less accessible for some individuals.
- Surgical Risks: Although rare, complications such as infection, inflammation, or increased eye pressure may occur.
- Potential Night Vision Issues: Some patients experience halos, glare, or difficulty with night vision after surgery.
- Regular Monitoring: Patients may need periodic check-ups to ensure the implanted lens remains in good condition.
- Not Suitable for Everyone: Individuals with certain eye conditions or health issues may not be eligible for the procedure.
Additionally, the possibility of needing future corrective procedures exists. If a patient’s prescription changes significantly over time, they may require additional interventions to maintain clear vision.
Potential risks and complications
Although ICL surgery is generally safe, some potential risks include:
- Increased Eye Pressure: The implanted lens may cause elevated intraocular pressure, increasing the risk of glaucoma.
- Cataract Formation: In some cases, ICL surgery may accelerate cataract development.
- Infection and Inflammation: As with any surgical procedure, there is a small risk of infection or inflammatory reactions.
- Retinal Detachment: Patients with high myopia have a slightly increased risk of retinal detachment following surgery.
Because the ICL is a foreign object in the eye, there is also a small possibility of long-term irritation or discomfort. If complications arise, the lens may need to be repositioned or removed altogether, requiring additional surgeries.
ICL surgery recovery time
The recovery period for ICL surgery is relatively short compared to other eye surgeries. Most patients experience improved vision within a few days, but complete stabilisation may take several weeks. During this period, patients should follow post-operative care guidelines, including avoiding strenuous activities and using prescribed eye drops.
Patients are usually advised to refrain from touching or rubbing their eyes, especially in the first few weeks after surgery. Vision fluctuations are common during the initial healing phase, and it is important to attend all follow-up visits to ensure proper healing.
Conclusion
Understanding the disadvantages of ICL surgery is crucial for making an informed decision. While it can provide effective vision correction, potential risks, recovery time, and long-term considerations should be taken into account. Consulting an experienced eye specialist can help individuals assess whether ICL surgery is the right choice f00or their vision needs.

Frequently Asked Questions
ICL surgery is designed to be a long-term vision correction solution. However, the lens can be removed or replaced if necessary. While the procedure is reversible, patients should consider that adjustments or removals require another surgical intervention.
Unlike LASIK, which permanently reshapes the cornea, ICL surgery does not alter the eye’s natural structure. This means that while the lens remains in place indefinitely, changes in vision due to ageing or other factors may still require additional corrections.
ICL surgery is not suitable for everyone. Individuals with the following conditions may not be ideal candidates:
Chronic eye diseases such as glaucoma or severe dry eye syndrome.
Unstable vision prescription, as further changes in eyesight may require additional correction.
Autoimmune disorders that affect healing and increase the risk of complications.
