Learn more about Higher order aberrations with Dr. John Gelles

It’s time for some Woo’s Wisdom! Dr. John Gelles gave a great talk on “The Rise of Wavefront Guided Scleral Lenses”. Let’s walk through some key takeaways:

👁️ According to the SCOPE study, 74% of prescribed scleral lenses are used for irregular corneas. Scleral contact lenses do a great job of correcting the optical aberrations caused by anterior corneal surface irregularity, but what about the rest of the eye?

👁️ Corneal scarring, irregularities of the posterior corneal surface, and lenticular opacities are among the frequent causes of decreased vision quality secondary to residual higher-order aberrations (HOAs) despite scleral lens wear.

👁️ The most common HOAs are coma, trefoil, and spherical aberration.

👁️ We now have access to great technology to measure aberrations and add them to scleral contact lenses to provide patients with the best possible vision outcome. Dr. Gelles reviews how to measure these, including the types of aberrometers available. Remember, it is important to have a stable fit and optimally correct the sphero-cyl refractive error in the scleral lens.
