1. Am I a good candidate for ICL? Generally speaking, ICL is suitable for patients between the ages of 21 and 50. ICL patients should preferably not have had eye surgery and should not have glaucoma, iritis, or diabetic retinopathy. 2. What is the range of correction for ICL in the United States? The correction range for farsightedness is +3.0 to +20.0D, for myopia is -3.0 to -20.0, and for astigmatism is +1.0 to +4.0. ICL is particularly effective for high myopia. 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 suturing. It also allows for predictable refractive correction and superior 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 cannot be noticed by a layman as you have had your vision corrected. 7.What material is ICL made of? ICL is made of collagen polyproducts exclusively from STAAR. It is made of small amounts of purified collagen polymerization, which is biocompatible and has no adverse reactions in the eye. 8.What is the procedure of ICL surgery? ICL surgery patients undergo light local anesthesia under normal conditions and can leave the hospital a few hours after the surgery when the eye pressure is observed to be normal. Post-operative care is easy. 9.How long can ICL stay in the eye? ICL is used in a way that it stays for a long time after implantation and requires no maintenance. 10.Will I feel any foreign body in my eye after ICL implantation? Usually the patient will not feel the presence of ICL in the eye. The implanted ICL will not bond with any tissue structure and will not move.
