Small incision lenticule extraction (SMILE) in the correction of myopic astigmatism: outcomes and limitations - an update

Eye and Vision, 2017
Small Incision Lenticule Extraction (SMILE) is a flap-free intrastromal technique for the correction of myopia and myopic astigmatism. To date, this technique lacks automated centration and cyclotorsion control, so several concerns have been raised ...

Case Report: Association of Ocular Colobomas With a Novel Missense Variant in CDC42, a Member of the Rho Family of Small GTPases

Clinical Genetics, EarlyView.
We report a 2‐year‐old male with clinical features of Takenouchi‐Kosaki syndrome, bilateral colobomas, and a de novo, likely pathogenic missense variant in CDC42. Supportive evidence includes a Cdc42 conditional knock‐out mouse model with colobomas.
