Abstract

Purpose

To report a case of suction loss during small incision lenticule extraction (SMILE) and a good visual outcome after switching to femtosecond laser-assisted in-situ keratomileusis (LASIK).

Case summary

A 20-year-old female was admitted to receive refractive surgery. During SMILE in the left eye, suction loss oc-curred at 65% of posterior cut completion. We switched to LASIK and SMILE was performed in the right eye as planned. The un-corrected distance visual acuity was 1.2 with a manifest refraction of +0.25 Dsph with 0 Dcyl. The patient had no complications at 3 months postoperatively.

Conclusions

Suction loss during SMILE is a rare complication. Good visual outcome was achieved by switching to LASIK. J Korean Ophthalmol Soc 2015;56(8):1274-1277
