Lens sizes: Why is this so important for accurate ICL surgery?

At London Vision Clinic, we provide a comprehensive range of tests for patients prior to ICL surgery, ensuring rigorous attention to detail, both in preoperative planning and postoperative follow-up. Our staff are highly trained and motivated to provide the highest possible level of care in this regard. The time taken during your visits reflects our commitment to providing our patients with the best and safest possible treatment.

The majority of providers, both in the UK and internationally, still use measurements of the outside of the eye to estimate the dimensions inside the eye, which in turn determine the lens size that should be implanted. However, the anatomy inside the eye where the lens will sit, does not always correlate sufficiently with the external measurements. The most advanced method for ICL sizing is to use the Artemis Insight 100 VHF digital ultrasound scanner to directly measure the area inside the eye behind the iris where the lens will be sitting.

What ICL sizing methods are used at London Vision Clinic?

It seems intuitively obvious that direct measurement of this space inside the eye will provide better information as to which ICL size to choose, than estimating this size from external measurements. It is important that patients be aware of the different sizing methods and ensure that surgeons are using this most advanced method to minimize the chance of complications or needing an ICL lens exchange surgery.

While risks associated with ICL surgery are low, these can include pupillary block, cataract formation, increased eye pressure, and glaucoma. The majority of these risks are associated with choosing the correct size lens.
