A. The difference in mean value of AT1 measured preoperative, after lenticule creation, and after lenticule extraction during SMILE.

, 2014
The mean value of AT1 after lenticule extraction was significantly lower than that before surgery and that after lenticule creation (post hoc ...

Effect of corneal stromal lenticule customization on neurite distribution and excitatory property

Journal of Advanced Research, 2022
Introduction: Refractive stromal lenticules from Small Incision Lenticule Extraction (SMILE), though usually discarded, hold a potential for various ophthalmic applications, including refractive correction, stromal volume expansion, and biomechanical ...

White ring sign for uneventful lenticule separation in small-incision lenticule extraction

, 2016
We describe the white ring sign, which differentiates the posterior and anterior lenticular planes in small-incision lenticule extraction. The sign identifies the plane of dissection by the anteroposterior relationship between the dissecting instrument ...

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...
