Abstract

Small incision lenticule extraction (SMILE) has become one of the mainstream refractive surgeries in recent years, with satisfactory efficacy, safety, and predictability. SMILE-derived refractive lenticule, the byproduct of the surgery, holds great potential in clinical practice given its easy access and good biocompatibility. Numerous studies have been published to describe its applications in refractive correction, corneal ectasia diseases, and corneal defects. The feasibility and safety were validated in both animal models and clinical studies. Moreover, the preservation method is also crucial for its further promotion and application. Novel techniques are also evaluated and applied in lenticule preservation. We covered the recent advances in the preservation of corneal stromal lenticules and their clinical reuse in this review.
