To help you determine if you are a good candidate for Visian ICL implantation, some useful information about Visian ICL is provided below are answers to some frequently asked questions: Q: How can I tell if I am a good candidate for Visian ICL implantation? A: Patients who are suitable for Visian ICL should be between the ages of 18 and 50, have myopia (with or without astigmatism), and want to achieve better vision correction. The ideal patient for Visian ICL should not have had any internal eye surgery and should not have a history of any of the following eye diseases, such as iritis, hypertension, glaucoma or diabetic retinopathy. Women who are pregnant or breastfeeding should not undergo Visian ICL surgery at this time. In addition, those with insufficient anterior chamber depth or low corneal endothelial cell density are also not candidates for Visian ICL surgery. The possibility of surgery is subject to a relevant examination and consultation by an ophthalmologist who is certified in Visian ICL, and the results of the examination will be used to evaluate whether the eye is suitable for surgery. Q: Where is Visian ICL implanted? A: The ophthalmologist will implant the Visian ICL into the eye through a tiny incision of 3mm, behind the iris and in front of the lens. The design of the Visian ICL does not touch any intraocular structures and no special care is required once it is implanted in the eye. Q: How is the Visian ICL being used? A: Visian ICL has been extensively researched and refined before it was introduced to the market. Now, more than 500,000 patients worldwide have received Visian ICL implants. In FDA clinical trials, more than 99% of patients were satisfied with the results of the procedure, and Visian ICL’s more than 10-year track record of use has shown stable clinical outcomes. Q: Is the procedure painful? A: No. The ophthalmologist will apply surface anesthesia during the procedure and may also administer some weak oral sedation. Most patients are comfortable throughout the procedure, sometimes with a little eye swelling or microscope light glare. Q: What materials are used to make the Visian ICL? A: Visian ICL is made of Collamer, a highly biocompatible, advanced crystalline material containing a small amount of purified collagen, which does not cause any reactions in the eye and also protects the eye with its UV filtering function. Q: What should I do if my vision changes after the Visian ICL is implanted? A: One of the advantages of the Visian ICL is its flexibility of treatment. If there is a significant change in your vision after the Visian ICL is implanted, your doctor can remove or replace the lens. A repeat procedure can be performed at any time of need. After the Visian ICL is implanted, patients can also wear glasses or corneal contact lenses as needed. The lens does not treat presbyopia (presbyopia, which usually occurs after the age of 45), but you will still be able to read with presbyopic glasses as needed after the Visian ICL is implanted. Q: What kind of surgical procedure is required to implant a Visian ICL? A: The procedure to implant a Visian ICL is very simple and painless. If you are a candidate for Visian ICL implantation, your doctor will order antiseptic drops to clean the eye surface 1-3 days in advance. The implantation itself takes about 10 minutes and can be done on an outpatient basis, but you will need to stay in the clinic for about 2 hours after the procedure before you can go home. During the Visian ICL implant procedure, you may experience minor discomfort, such as eye swelling and microscope light glare. The procedure may be performed under surface or local anesthesia, or you may be sedated orally. After surgery, you will need to use some eye drops or oral medication as prescribed by your doctor. You will need to see your doctor for a follow-up the day after surgery. You will also need to have a review at 1 month and 6 months after surgery. Q: Can Visian ICL be removed from my eye? A: Although it is intended to be permanently implanted in the eye, it can be removed by a board-certified ophthalmologist if necessary, and you will still be able to wear glasses as needed after the ICL is removed. Q: Can Visian ICLs be seen by others? A: No. The Visian ICL is located behind the iris (the colored part of the eye), so neither you nor anyone else can see the lens. Only your doctor will be able to tell that you have had your vision corrected with special equipment. Q: Will I be able to feel the lens after the Visian ICL is implanted? A: The Visian ICL is designed so that there is no irritation at all after implantation. The lens is very quiet in the eye and does not react with any intraocular tissues. Q: What are the advantages of the Toric ICL (which has the ability to correct astigmatism at the same time)? Does the toric lens tend to shift A: The Toric ICL has excellent predictable results, correcting nearsightedness or farsightedness while simultaneously correcting up to 500 degrees of concomitant astigmatism, resulting in excellent visual quality. The astigmatic lens is also implanted in a small space behind the iris and is unlikely to move without external forces. To ensure the accuracy of astigmatism correction, the eye should not be rubbed after surgery to avoid external forces that may cause deformation of the eye and displacement of the ICL. Normal sports and lifestyle activities will not cause the lens to shift. The implantation procedure itself takes approximately only 10 minutes and can be performed on an outpatient basis. Other treatments are the same as for non-astigmatic lenses. Q: Can I keep the ICL for the rest of my life after it is implanted in my eye? A: After ICL implantation, you need to have regular review with your ophthalmologist to assess the safety of your eye with professional instruments, and if the condition is stable, you can keep the ICL in your eye. If the position of the ICL changes with age, the doctor will recommend removing or replacing the ICL with a new one after the instrumentation has checked that the ICL is no longer suitable for placement in the eye. In addition, as we age, after the age of 50 or 60, cataracts will occur in our own lens, which is age-related and has nothing to do with ICL. Q: Can I get more information about Visian ICL? A: If you wish to undergo Visian ICL surgery and would like to learn more about Visian ICL, you can contact an ophthalmologist certified by STAAR?
