Summary

In recent years, many scholars have studied the ocular surface damage of patients with dry eye disease（DED）after FS-LASIK, but there has been a lack of comprehensive observation and research on the relationship and difference between dry eye （DE）patients with and without LASIK. Therefore, the purpose of this study was to investigate the characteristics of ocular surface and cytokines after FS-LASIK, and further explain the pathogenesis of chronic dry eyes after FS-LASIK. In addition, we will also compare clinical characteristics and tear neuropeptide concentrations in patients with dry eye disease (DED) with and without chronic ocular pain following FS-LASIK, and to investigate correlations between ocular pain, clinical characteristics, and tear neuropeptide levels.

Conditions

Interventions

PROCEDURE

FS-LASIK

Laser-assisted in situ keratomileusis, commonly referred to laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hypermetropia, and astigmatism.
