**5. Conclusions**

In conclusion, both FLACS and MCS can induce dry eye. The adverse effects of FLACS on the ocular surface are more severe in FLACS than in MCS. Fortunately, these effects are transient and are resolved within three months after surgery. Cataract surgeons should select FLACS candidates carefully and adopt preoperative evaluation and postoperative therapy for dry eye. Further studies are warranted to verify and understand the post-FLACS dry eye mechanism.
