ICL Sizing

Anterior Segment Imaging and Biometry

The ArcScan Insight® 100 images provide unmatched accuracy to obtain measurements in the entire anterior chamber. The goal is to reduce lens exchanges to a very rare event as opposed to a 2% exchange rate. London Vision Clinic states, “The most advanced method for ICL sizing is to use the…Insight 100 VHF digital ultrasound scanner to directly measure the area inside the eye behind the iris where the lens will be sitting.” The ArcScan Insight® 100 provides accurate biometry for pre-operative and post-operative IOL, premium IOL, and ICL. This can allow the clinic to evaluate accurate lens position, tilt and volume.

Phakic Lens Sizing

White-to-white measurements has been a common practice in ICL sizing; however, regardless of these exterior measurements, most doctors are still unable to predict the diameter of the sulcus within 0.5mm.

At least 25% of eyes will still end up with >0.5mm error, in terms of predicting the sulcus,” Dr. Dan Reinstein.

Post Operative Imaging

Utilizing the Insight 100 for post op imaging of implanted lenses can reveal potential causal factors of improper lens positioning. In this case the ICL footplate sits atop a ciliary body cyst. Rotation of the lens resulted in proper alignment and positioning. The insight 100 provides stunning image resolution and ability to see behind the iris. This insight can aide the surgeon in therapy planning.

Watch how the ArcScan Insight® 100 allows the operator to take measurements (Pre-Operative and Post-Operative ICL) using the tools within the instrument to place calipers on the images are captured.

FREE Website to Determine ICL Sizing

As of September 14th of 2019, at the Paris ESCRS, a new free website was launched for surgeons to determine proper ICL sizing. This site created by London Vision Clinic can be accessed at www.iclsizing.com

Phakic lenses are surgically implanted in the posterior chamber, occupying the slit-like potential space between the posterior surface of the iris and the anterior surface of the crystalline lens. Due to the small space here, and the need for aqueous humor to pass through the pupil space, it is critical to pre-operatively measure this area where the lens will be implanted. Only ultrasound imaging can accurately image behind the iris. The ArcScan Insight® 100’s measuring calipers are accurate to within 0.12mm laterally behind the iris and therefore considered the “Gold Standard” for imaging and measuring this space.
