New Publication Alert! 🚨
We took a look at highly myopic eyes (

The CORL Team is excited to announce the publication of our new article on myopia in Ophthalmic & Physiological Optics (OPO). This article explores the impact of zone geometry of multizone lenses and offers valuable insights for myopia control. It’s great to see our diligent efforts come to fruition, and we are optimistic that our research will make significant contributions to future studies in this field.

Impact of zone geometry on the introduction of myopic defocus in young adult eyes wearing multi‐zone lenses Purpose Multizone contact lenses control myopia progression by proposed introduction of myopic defocus. This project investigated how much of the pupil area and how many dioptres of myopic defocus a...

Another successful CORL competition! Congrats to our 1st place winner, Kaitlyn, with her "5-course meal on a stick" and Emily's 2nd place "mini goat cheese balls on pretzel sticks!"

What is the optical impact of dual focus (DF) contact lens in children during accommodation? – is the question that researchers from Clinical Optics Research Lab, Indiana University, Aston University and Coopervision answer in this paper. We measured the optics of children eyes treated with a dual focus and control monofocal contact lens using a high resolution aberrometer during active accommodation. The distribution of refractive states and defocus across the eye pupil together with the complex power distribution of the dual focus lens was well characterized by histogram and ternary plots. Key results include a) Myopic shift in the mean defocus across the pupil (from +0.75 D to -1.00 D) by the treatment optics of the DF lens, b) Reduction in the % of hyperopic defocus in the retinal image from 52% to 25% and associated increase in myopic defocus from 17% to 42% and c) unaltered accommodative behavior in children with the DF lens.

Myopia Control Dose Delivered to Treated Eyes by a Dual Focus Myopia Control Contact Lens - PubMed The DF contact lens did not alter the accommodative behavior of children. The treatment optics introduced myopic defocus and decreased the amount of hyperopically defocused light in the retinal image.

Congratulations to our CORL 2023 grads! We are so proud of your hard work and can't wait to see what amazing things you will do!
