Where vision correction is concerned, EVO Implantable Collamer Lenses (ICL) has become another choice to consider for individuals who no longer want to depend on conventional alternatives like LASIK. For those who prefer to have better vision without having to do a morning routine of contacts or glasses, EVO ICL is an apt choice. Is it, however, the best choice for you?
What is EVO ICL?
EVO ICL, also known as “implantable collamer lens,” is a refractive surgery for nearsightedness, farsightedness, and astigmatism. LASIK is actually a recontouring of the cornea, whereas EVO ICL is inserting a specially designed lens into the eye. It’s very minimally invasive, and the lens goes behind your iris and in front of your natural lens in your eye. It functions in conjunction with your eye’s natural system to improve vision.
One of the other features of EVO ICL is that it is reversible, even though the implanted lenses are meant to remain permanently. This is attractive to those patients who would like to have a reversible process, if in the future they may need additional treatments or technologies.
How EVO ICL is Different from LASIK
For most vision correction candidates, LASIK is the first procedure that they are considering. Yet, EVO ICL is different in several significant ways that can influence your choice.
For one, EVO ICL from the likes of IQ Laser Vision is ideal for a patient with a thin cornea or high myopia, conditions which would otherwise disqualify a patient as a candidate for LASIK. Since LASIK is a corneal reshaping procedure, it is limited by the thickness of corneal tissue. EVO ICL doesn’t reshape the cornea and thus is a superior option for a patient with a thin cornea.
Second, LASIK is permanent and cannot be removed, whereas EVO ICL is not. The lenses that are implanted can be removed or replaced when needed, so patients can have the assurance that future advances in vision correction technology will be to their advantage.
Third, although the dry eye complication occurs for patients who have LASIK, EVO ICL typically has no such restriction because it does not entail sacrificing the nerves of the cornea.
Advantages of EVO ICL
One of the most obvious advantages of EVO ICL is the accuracy and clarity of vision it creates. Patients have a greater likelihood of being described as having razor-sharp and more crystalline vision compared to some other forms of correction. Much of this is due to the highest-quality biocompatible collamer material of the lenses, which changes in harmony with your eye.
Another enormous advantage is the reversibility. In case your prescription shifts, or you want to leave space for future operations, EVO ICL can be removed or reduced without any permanent alteration to your eye.
There is also greater prescription versatility and eye types. High myopia, astigmatism, and thin corneas are usually not good candidates for LASIK, but with EVO ICL, the procedure can often be performed.
Finally, the short healing time is an advantage. Vision becomes better in most patients shortly after surgery, and full recovery is achieved within a few days.
Disadvantages of EVO ICL
Despite its advantages, there are some potential disadvantages to consider. EVO ICL is expensive compared to LASIK or PRK. Insurance only partially covers this elective procedure, so the majority of patients need to pay out-of-pocket.
The second is the surgical nature of the process. Though minimally invasive, EVO ICL does consist of making a small incision to place the lens, and there is some small but real risk of having complications such as infection, cataracts, or increased intraocular pressure.
In addition, similar to LASIK, EVO ICL also does not correct hyperopia (farsightedness) as well. Depending on your individual vision needs, this can make it less desirable.
It’s also noteworthy that even though the lenses can be adjusted, they are not one-time-only for each patient. There are some that will need to undergo future surgery or get replaced lenses later.
All in All
Selecting the most appropriate vision correction surgery is a highly personal choice on your part, depending on your own needs, lifestyle, and medical appropriateness. EVO ICL boasts unmatched benefits such as reversibility, flexibility, and treatment options with more prescriptions, but with some limitations such as cost and surgical complications.
The best route is to make an appointment for a consultation with an experienced ophthalmologist to determine whether or not EVO ICL would be a suitable option for you. Don’t hurry – take your time weighing the pros and cons before coming to a conclusion.
