ICL surgery is performed as a day-case procedure lasting 15 minutes per eye. Both eyes are typically treated on the same day. 

ICL implants are a popular and safe alternative to laser refractive surgery, with an excellent track record over the 20 years since their introduction. More than 1,000,000 lenses have been implanted worldwide and the ICL system has earned a reputation for proven patient satisfaction and long-term safety.

Short-term discomfort after ICL surgery is to be expected. Grittiness, light sensitivity, dryness and tearing are also common for the first few days. Many patients experience glare and haloes around lights for a few months following the implantation of the ICL, but these symptoms generally become less noticeable with time. The risk of a serious complication, principally infection, during the first few days following ICL surgery is approximately 1 in 6000. An infection inside the eye (endophthalmitis) may cause permanent damage to your vision.

Up to 1 in 40 cases require an adjustment of the ICL or replacement of the ICL. This would typically be due to the ICL not sitting correctly inside the eye. Adjusting or replacing the ICL would involve a further operation. No additional charge would apply for this.

Early development of cataract may also occur. In published studies, with up to 7 year follow-up data, between 1 – 2% of patients have required cataract surgery to restore vision following ICL implantation. Newer ICL designs have a central port (CentraFLOW®) which allows for normal flow of fluid within the eye. This will likely further reduce the risk of cataract.

Yes. Annual review of your vision and eye health with a high-street optician is recommended to monitor for the main long-term risks of cataract formation and raised pressure in the eye.
