ICL lenses in Turkey are one of the latest technologies used to correct vision defects, and have been an advanced option for patients who are not suitable for laser vision correction procedures such as LASIK or PRK. This technology involves implanting a special lens inside the eye without removing any part of the cornea, allowing high-accuracy correction of nearsightedness, farsightedness, and astigmatism and eliminating the need for glasses or contact lenses in daily life.
What are ICL lenses?
ICL, or Implantable Collamer Lens, is a flexible intraocular lens implanted between the iris and the natural lens. These lenses are made from Collamer, a combination of collagen and bioplastic, which gives them a high degree of biocompatibility and flexibility. ICL lenses allow oxygen and nutrient fluids to pass naturally into the eye, are fitted without affecting the original eye structure, and can be removed or replaced as needed, making them a safe and effective long-term option.
How do ICL lenses work?
ICL lenses correct vision defects by redirecting light rays precisely to the retina, so that the image is formed clearly and without distortion. The lens is implanted inside the eye between the iris and the natural lens, acting as an additional lens that complements the eye’s visual function without the need to remove or modify the corneal tissue. Thanks to this principle, ICL lenses preserve the integrity and natural structure of the cornea, making them a suitable option for patients whose corneal thickness does not allow for laser vision correction.
Types of ICL lenses
ICL lenses are available in several types, and choosing the right one depends on the type and degree of visual impairment, as well as the exact measurements of the eye. Each type aims to optimize the focus of light within the eye and achieve the best possible quality of vision.
ICL lenses for myopia correction
These lenses are used to correct nearsightedness of various degrees, including high degrees that may not be treatable with LASIK. The lens helps modify the path of light so that it focuses directly on the retina rather than forming in front of it, resulting in a clearer view of distant objects without the need for glasses or contact lenses.
ICL lenses for hyperopia correction
ICL lenses for farsightedness improve the eye’s ability to focus light from near and far objects in a balanced manner. These lenses are an effective option for patients with moderate to high farsightedness, especially when laser vision correction is not appropriate.
ICL lenses to correct astigmatism
These lenses are designed to correct astigmatism caused by the irregular curvature of the cornea or natural lens. Toric ICL lenses modify different light paths within the eye, helping to minimize visual distortion and improve clarity of vision for both near and far objects.
Who are the right candidates for ICL implants?
ICL implantation is a suitable option for a specific group of patients, determined by age, degree of visual impairment, and eye health, with prerequisites including the following:
- Age between 21 and 45
- Myopia ranging from -4 to -20 diopters
- Farsightedness ranging from +2 to +10 diopters
- Astigmatism ranging from 0.5 to 6 diopters
- Stabilization of optometry during the previous period
- Ineligibility for laser vision correction procedures such as LASIK or PRK
Who is not a good candidate for ICL lenses?
Although ICL lenses are safe and effective, they are not the best option for all patients, as there are some conditions that may preclude this type of surgery, including:
- Active infections or chronic eye disease
- The anterior chamber of the eye is too narrow to safely implant the lens
- Uncontrolled high eye pressure
- Having some advanced retinal diseases
- Pregnancy or breastfeeding at the time of the procedure
- Optometric instability
Tests needed before implanting ICL lenses
Before making the decision to implant an ICL, the patient undergoes a comprehensive eye and general health evaluation to ensure the procedure is appropriate and safe. Basic tests include the following:
- Measurement of anterior chamber depth and drainage angle between the cornea and iris
- Comprehensive eye examination with a full medical history
- Make sure your optometry is stable for about a year
- Evaluating the shape of the eye and its suitability for lens implantation
- Measuring the thickness of endothelial cells in the cornea
- Checking eye pressure
- Retinal and fundus examination
- Review the medications the patient is using and determine what should be stopped before the procedure
The doctor also provides special instructions before the surgery, such as stopping eating or drinking if necessary, or temporarily stopping certain medications, in addition to the need to provide a companion to take the patient to and from the medical center.
Steps of the ICL lens implant process
The implant procedure is safe and accurate, often without the need for an overnight hospital stay. The process goes through several sequential stages, including:
- Pupil dilation and eye anesthesia using special drops
- Give a mild tranquilizer to help the patient relax when needed
- A very small incision in the cornea
- Inserting the folded lens through the slit
- Fixing the lens behind the iris and in front of the natural lens
- Leaving the incision to heal on its own without the need for stitches
Thanks to the small size of the incision, the procedure is virtually painless and the integrity of the eye tissue is preserved.
After ICL lens implant surgery
After the procedure is complete, the doctor will provide instructions to ensure proper recovery and the best visual outcome. The post-operative phase includes the following:
- Check eye pressure several hours after the procedure
- Return home the same day with an escort, no driving allowed
- Use eye drops to prevent inflammation and infection for several weeks
- Doing light daily activities such as reading, watching TV, and working on the computer
- Medical review the day after surgery
- Gradual improvement in vision during the first few days to the first week
- Avoid rubbing your eyes for a month
- Wear eye protection while sleeping
- Avoid heavy lifting or any activity that puts pressure on the eye
If you experience mild discomfort during the first 24 hours, you can use simple painkillers as directed by your doctor.
Advantages of ICL lens implants
ICL implants offer several advantages, making them an effective option for correcting vision defects, especially for patients who are not suitable for laser vision correction. These include rapid improvement in the quality of vision without the need for glasses or contact lenses, with long-lasting results that can last a lifetime.
These lenses can be removed when needed without causing structural damage to the eye, with a low risk of dry eye and improved night vision for many patients. Studies show that satisfaction with this procedure’s results is very high, with about 95% of patients expressing satisfaction or complete satisfaction.
Possible ICL lens implant risks and complications
Although the procedure is safe and has a high success rate, as with any surgical procedure, it may involve potential risks or complications. These complications include bleeding or inflammation inside the eye, as well as glare and light halos, especially during the first period after the procedure. Some patients may also notice a temporary increase in eye pressure or increased sensitivity to light, which usually improves spontaneously with medical follow-up and appropriate treatment.
Are ICL lenses better than LASIK?
Choosing the most appropriate vision correction technique depends on the condition of the eye, the degree of visual impairment, and the corneal thickness. Below is a brief medical comparison that explains the basic differences between ICL, LASIK, and FemtoLASIK lenses:
| Criterion | ICL lenses | Lasik | Femto-Lasik |
|---|---|---|---|
| Correction method | Intraocular lens implantation | Laser corneal reshaping | Advanced Laser Corneal Reshaping |
| Impact on the cornea | No tissue is removed | Removing part of the corneal tissue | More precise and controlled removal |
| Suitabilty for a thin cornea | Suitable | Often inappropriate | limited |
| Suitability for a thin cornea | Very convenient | limited | limited |
| Removability | The lens can be removed or replaced | Non-reversible | Non-reversible |
| Risk of dry eye | less | Relatively higher | Less than LASIK |
| Speed of vision improvement | Very fast | Fast | Fast |
Long-term results of ICL lens implantation
The implantation of these lenses shows stable, reliable long-term results, as the lens maintains its corrective effect without altering corneal structure or causing progressive changes in the ocular surface. Most patients experience high, stable vision quality for many years, with very high satisfaction rates, especially among those who were previously high-vision patients or did not qualify for laser surgery. With regular medical follow-up, the results of ICL lenses are one of the most stable long-term vision correction solutions.
Can ICL lenses be removed or replaced?
Yes, ICL lenses are a reversible technology, as the lens can be removed or replaced if your vision changes in the future or a medical reason arises. These procedures are done without causing permanent damage to the eye structure, which gives this technology an added advantage over laser vision correction, which is irreversible.
ICL Lens Implant Cost
The cost of ICL lens implantation varies from one country to another based on several factors, most notably the type of lens used, the experience of the surgeon, the level of the medical center, and the accompanying services before and after the procedure.
| Country/Region | Approximate cost of ICL lens implant (both eyes) |
|---|---|
| Turkey | 2,500 – 4,000 USD |
| United States | 6,000 – 9,000 USD |
| Gulf States | 4,500 – 7,500 USD |
In some centers, the cost may include pre-operative tests and post-operative follow-up, while in others it is calculated separately.
In conclusion, ICL lenses are an advanced and effective option for correcting visual defects in patients who are not suitable for laser vision correction, especially in cases of high myopia or thin corneas. The technique is characterized by the preservation of the eye’s natural structure, long-term stability of results, and very high satisfaction rates. Careful eye evaluation and regular medical follow-up are the keys to ensuring the safety of the procedure and achieving the best possible quality of vision.
