ICL is an implantable lens technology to correct myopia. Its advent has changed the way femtosecond laser, LASIK, PRK and other cutting procedures for refractive correction are performed. The most important difference between ICL and laser surgery is that ICL is a reversible treatment and ICL lens implantation does not permanently change the shape and structure of the eye, according to a well-known national refractive specialist. However, there are still many friends who have doubts about ICL. Here we have collected the top ten most frequently asked questions about ICL and given answers to them: 1. Am I suitable for ICL? ICL is suitable for patients between the ages of 18-47. ICL patients should preferably not have had eye surgery and not have glaucoma, iritis, or retinopathy caused by diabetes. 2. What is the correction range of ICL? The correction range for myopia is 225 degrees to 2000 degrees, for hyperopia is 1000 degrees, and for astigmatism is 600 degrees. 3.What are the advantages of ICL? ICL can be used to correct a wide range of myopia, hyperopia and astigmatism without removing or destroying corneal tissue and without post-surgical sutures. It also allows for predictable refractive correction and excellent visual quality. 4. What if the patient’s vision changes? If a patient’s vision changes significantly and the ICL is no longer suitable, the ICL can be removed or replaced at any time. After the ICL is implanted, patients can still wear glass or contact lenses. 5. Will ICLs dry out or become contaminated like contact lenses? No. ICLs are designed to be implanted inside the eye without maintenance. 6. Can ICLs be seen from the outside of the eye? No. ICL is implanted behind the iris and cannot be seen from the outside by anyone, including the patient themselves. ICL is cosmetically perfect and lay people will not be able to notice that you have had your vision corrected. 7.What material is ICL made of? The raw material of ICL is Collamer, an exclusive product of STAAR, which is made of small amount of purified collagen polymerization and has good biocompatibility without any adverse reactions in the eye. 8.How is the process of ICL surgery? ICL surgery patients receive light local anesthesia under normal conditions for the surgery and can be discharged on the same day. Post-operative care is easy. 9.How long can ICL stay in the eye? ICLs are implanted for a long time and require no maintenance. 10.Will I feel a foreign body in my eye after ICL implantation? Usually, patients do not feel the presence of ICL in their eyes. The implanted ICL will not bond with any tissue structure and will not move.
