Implantable Contact Lenses (ICL)
Another form of contacts are able to treat high levels of nearsightedness. It works like a contact lens and the procedure aims to correct refractive error without compromising the integrity of cornea structure. It is an alternative for those who are not declared good candidates for LASIK. It acts just like a contact lens but instead of being worn on the surface, it is directly placed inside the eye, or behind its structure, the iris.
At Shinagawa, we use phakic intraocular lens (Swissmed VISIAN ICL) for our ICL procedures to ensure the best quality for our patients.
Advantages of ICL
- Will not ablate (reshape) the cornea
- Suitable for those with the highest intensity myopia
- No need to change lens, no return of myopia
- Long-term stability
- Japanese and American FDA Approval
- 90% of UV protection
What ICL can correct
- Nearsightedness
- Astigmatism
ICL is recommended for:
- People with either high myopia, thin cornea, and/or keratoconus
- Those who have resistance to cutting the cornea with LASIK
- Those who want to enjoy sports without eyeglasses
How does ICL procedure works?
In a nutshell, the ICL procedure is reversible and is designed to correct both high myopia and astigmatism, which are a huge advantage already. Further, in cases that a prescription changes, the ICL is reversible and replaceable, meaning it can maintain your vision for a long period of time. Also, the procedure is painless and allows rapid recovery of vision
Another key matter with the procedure is that it doesn’t change the shape and thickness of the cornea significantly. Given that, cornea related complications will be avoided in the process.
Moreover, the inserted lens include UV protecting properties that prevents any harmful UVA and UVB rays from getting to the yes. Compared to cornea based ablation treatments, the ICL procedure presents a significantly shorter period of recovery. The procedure also presents no dry eye condition as no stimulating tearing nerves are abolished
While you feel the presence of contact lenses, the same can’t be said for ICL as you basically can’t feel it in your eye. Maintenance won’t be a problem as well as ICLs don’t require it.
Here are more key facts about the ICL:
• It is capable of correcting high degrees of nearsightedness that cannot be rectified by other eye surgical procedures.
• A great alternative for LASIK as it is performed to patients who have corneal thinness and irregularity.
• Can be removed surgically anytime
As we know, both beneficial eye procedures help patients achieve perfect and clear vision minus the need for glasses or contact lenses. Still, they are two different vision-correcting procedures that are conducted in very different ways with different specifications.
While we know that LASIK can do a lot of wonders for one’s vision, not everyone qualifies as a good candidate for LASIK. That’s where ICL procedure comes in as it allows those who don’t qualify for LASIK an effective alternative to enhance their vision.
Contrary to LASIK, ICL does not alter the shape of the cornea. As an alternative to LASIK, ICL provides vision correction that goes beyond LASIK in certain cases. The procedure enables you to enjoy crisp sharp and rich vision with good color contrast and enhanced night vision in certain cases as opposed to LASIK.
Currently, LASIK is the most popular and preferred type of refractive surgery for convenient and effective reasons. Safe and tested with advanced technology, LASIK makes visual outcomes better even more.
As earlier mentioned, however, now everyone can be a good candidate for LASIK surgery, leaving those selected few to look for an alternative which the ICL procedure can provide. Having too much astigmatism, nearsightedness or farsightedness; extra thin or irregularly shaped cornea; and having certain eye conditions like keratoconus and dry eye syndrome forces one to not be eligible for LASIK.
For those who are not deemed a good candidate for LASIK, ICLs might be better suited.
While the LASIK Procedure relies on a laser to remove tissues from the cornea to be able to correct and enhance vision, ICLs, on the contrary, do not require the removal or altering of the corneal tissues as vision is corrected through the placement of a lens inside the eye instead.
So if one will not qualify for LASIK, ICL Procedure can be the answer as it can likewise provide excellent results, too.
Normally, candidates are between the ages of 21 to 45 years old. These candidates are the ones who suffer from moderate to high myopia of up to -19.0 Dioptres, hypermetropia of up to +10 Dioptres and astigmatism of up to 6 Dioptres. Preferably, candidates should not have any eye diseases, systemic conditions like hypertension and diabetes, and lastly, no previous surgeries done.
ICL Procedure is basically for people who have thin cornea and/or refractive error. They are also those who are most probably not qualified to undergo LASIK.
Here are some more factors that determines a good candidate for ICL Procedure:
Have a prescription for glasses or contacts that has not changed significantly in the past year
• Have good general and eye health
• No history of chronic dry eyes
• Not pregnant during time period of procedure
Key notes:
*Patients who undergo ICL Procedure are still eligible for cataract surgeries in the future, if deemed necessary
*Patients beyond 45 years old are most often recommended to have lens replacement surgery through multifocal lens implantation
ICL Implantation Process
The entire ICL procedure normally lasts between 20-30 minutes. It is an outpatient surgery and the patient can go home after the entire treatment.
It is important for the incision to be extremely small that is self-healing. The good thing about the ICL Procedure is that it is proven to be safe and effective as it does not modify the thickness and the shape of the corneal tissue in any way.
Together with the eye’s natural lens, the implanted ICL lens are certain to improve vision. As mentioned, it is a perfect alternative for LASIK as those who will fail to qualify for that procedure will have a fallback option that improves visions permanently.
Generally, the risks that come with ICL is significantly low. Still, given that it is an intraocular procedure, there’s still a risk of sight threatening complications. But as mentioned earlier, the procedure presents minimal risks. Following the surgery, daily activities, with minimal maintenance, can already be continues.
Just like every other surgical procedures, ICL has its own risks. Possible complications, short and long term, include:
- Cataract – Clouding of the eye’s natural lens that causes cloudy and blurry vision, possibly blindness if left untreated. However, cataract removal through surgery is one of the most effective procedures.
- Blurry and Distorted Vision – Such visions may occur for a stretch following the procedure but these visual symptoms eventually disappear or decrease upon the healing of the eye.
- Infection of the Eye – Such complications can be reduced or avoided with corresponding anti-inflammatory and antibiotic medications.
- Glaucoma – A significant eye pressure that can cause damage to the optic nerve and eventually, vision loss. To control the pressure, medications for Glaucoma are prescribed.
- Retinal Detachment – In this case, the retina gets separated from its supportive tissue, causing one to experience poor vision.
However, these risks are low and minimal, fortunately, making it a proven safe procedure.
As aimed by the procedure, majority of the patients would already notice significant improvement in their vision several hours after the surgery. Still, improved vision might be blurry with increased sensitivity for the first few days after the procedure. Optimal effects are expected to be felt and noticed around seven days, more or less.
Naturally, minimal discomfort is expected following the ICL Procedure. Should it be necessary, a patient can be prescribed a medication for more comfort in the following days post-surgery.
A patient is required to return for a follow-up checkup a day after the surgery to see immediate progress and effects. In order to have a safe and sound recovery, following every post-operative instructions carefully are musts to avoid any complications that may arise.
In line with this, it is likewise important to strictly avoid rubbing the eye, as well as having vigorous activities until after several weeks when the eye has completely healed.
Following the surgery, most patients can actually return to work the soonest and resume driving after a couple of days, provided that they already have a go-signal from the doctor.
