Why Are Lens Sizes So Important for Accurate ICL Surgery?
At London Vision Clinic, we pride ourselves on our dedication to performing rigorous testing for each treatment we offer. Our comprehensive range of tests ensures strict attention to detail, whether a patient is interested in Laser Eye Surgery or ICL Surgery.
So, from our pre-operative planning to our post-operative follow-ups, you can be sure you’ll receive the very best care from every member of our highly-trained staff. The time taken to complete your consultation reflects our commitment to achieving the best and safest possible outcomes. When it comes to ICL Surgery, this includes collecting accurate measurements to determine the best lens size for you.
Most providers, both in the UK and around the world, use measurements taken from the outside of the eye to estimate the dimensions inside the eye. These figures are, in turn, used to determine the correct lens size. However, external measurements don’t always correlate with the internal anatomy of the eye.
At London Vision Clinic, we use more advanced methods to determine the best ICL sizing…
What ICL sizing methods are used at London Vision Clinic?

It might seem obvious that measuring the inside of the eye will provide the most accurate dimensions for ICL sizing. Unfortunately, not all clinics have access to the technology required to collect this data. But at London Vision Clinic, we do.
The most advanced method for ICL sizing is to use the Artemis Insight 100 VHF digital ultrasound scanner. This state-of-the-art scanner allows us to directly measure the area inside the eye behind the iris where the lens will be sitting. The Artemis Insight 100 was developed by our very own founder and expert surgeon, Professor Dan Reinstein.
Patients should be aware of the best practices when it comes to ICL Surgery (and all types of refractive surgery). Ensure that your chosen clinic uses this most advanced method for ICL sizing. Doing so can help to minimise the risk of complications or requiring an ICL lens exchange surgery.
Generally, the risks associated with ICL Surgery are low; however, the majority of risks – including pupillary block, cataract formation, increased eye pressure, and glaucoma – are associated with choosing the correct size lens.
