[Advances in the research of femtosecond laser-assisted lenticule intrastromal keratoplasty for the correction of hyperopia].

Abstract

Lenticule intrastromal keratoplasty (LIKE) was introduced clinically in the 1980s as a refractive surgery. With the advancements of femtosecond laser, LIKE has been significantly revitalized. Currently, femtosecond laser-assisted LIKE has been demonstrated to be a safe and effective surgical procedure to correct hyperopia, but the predictability is still a major limitation. In this article, we review the history, procedures, influencing factors of predictability and challenge of LIKE to provide reference for clinical practice of femtosecond laser-assisted LIKE.
