Today, we will be looking into ICL (Implantable Contact Lens) surgery, which is gaining attention for its lower risk of myopia regression compared to other vision correction procedures. Unlike methods that involve cutting the cornea, ICL surgery involves inserting a lens into the eye without any corneal damage, allowing for a quicker recovery. However, concerns may arise about the lens breaking or causing an inflammatory response after the surgery. We will address these concerns and provide a detailed explanation.
Lens implantation surgery can be divided into anterior lens implantation and posterior lens implantation, depending on the position where the lens is inserted during the procedure. Common types of lenses used in this surgery include Aqua ICL, Toric Aqua ICL, Artisan, Artiflex, and Toric Artiflex. Among these, Artisan and Artiflex lenses are used for anterior lens implantation, where the lens is directly fixed to the iris after making a tiny incision in the toughest and most durable tissue of the eye, the iris. On the other hand, Aqua ICL and Toric Aqua ICL lenses belong to posterior lens implantation, where the lens is positioned between the iris and crystalline lens, without the need for an incision in the iris. Posterior lens implantation, which is preferred for its pain-free procedure and fast recovery, involves inserting the ICL lens through a tiny corneal incision between the iris and crystalline lens.
The characteristic of ICL (Implantable Contact Lens) surgery is that it preserves the cornea while correcting vision. Unlike surgeries like LASIK or LASEK, which require creating a corneal flap or making corneal incisions, ICL surgery does not involve cutting the cornea. Instead, it only requires a minimal incision around the cornea to insert the lens between the iris and crystalline lens. Since the cornea and crystalline lens remain intact, this surgery can be performed even in cases where the cornea is thin or has an irregular shape.
Among the lenses used in ICL (Implantable Contact Lens) surgery, the EVO+ Aqua ICL lens stands out. The EVO in its name stands for Evolution in Visual Freedom, and it is made of biocompatible material, which ensures smooth integration with the eye and minimizes inflammatory responses. To address the previous issue of disrupting the flow of aqueous humor, a tiny 360μm hole is created at the center of the lens to ensure the smooth flow of fluid in the eye. This feature significantly reduces the likelihood of glaucoma-related complications. Additionally, the EVO+ Aqua ICL is made from a collamer material that has been approved by the FDA and is highly biocompatible. This means the lens does not cause discomfort in the eye after insertion. Compared to previous lenses, the optical zone of the EVO+ Aqua ICL is wider, allowing for clear vision without glare, even when the pupil dilates. Furthermore, it has a lower risk of causing side effects such as iris blockages or white lines. The fact that the incision size is smaller means that recovery time is faster. By following post-surgical instructions carefully, patients can minimize the potential for side effects such as corneal diseases or dry eyes. ICL surgery offers the advantage of being suitable for a wide range of patients, including those with high myopia, astigmatism, thin corneas, or large pupils.
Lens implant surgery is considered a highly safe procedure, but it also requires a high level of skill. This is because each person has different eye shapes and sizes. If the special lens is either too small or too large for the eye space, dizziness, blurry vision, and other issues can arise after the surgery. Therefore, it is essential to measure the eye space accurately and insert the lens in the correct position. Additionally, it is crucial to determine the appropriate type and size of the lens that suits each individual’s eye condition, lifestyle, and physical attributes before performing the surgery. Therefore, if you are considering ICL surgery, it is highly recommended to consult with a skilled and experienced doctor who holds the ICL Doctor Certification and make a well-informed decision.
