Great news for surgeons and patients using EVO-ICL
Our study shows that the formulas for calculating the size of ICL Nakamura V2 and V3 do not seem to differentiate patients according to their ethnicity. This is an important step forward in ensuring results. predictable and repeatable in ICL surgery in diverse populations.
Why is it important?
These results allow surgeons to use these formulas with confidence with a variety of patients, without compromising on the safety or quality of the results.
The scientific article was published in the Journal of Refractive Surgery.
“Congratulations to Chris Ashton for successfully carrying out this project.
It was also a real pleasure to collaborate again with former colleagues and mentors at Moorfields Eye Hospital in London: Mr Tjebo Heeren, Prof. Bruce Allan, Mr Vincenzo Maurino and Mr Daniel Gore.”
