A Case of Suction Loss During SMILE and a Switch to LASIK

  • 1Onnuri Smile Eye Clinic, Seoul, Korea. ytchungc@daum.net


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).
A 20-year-old female was admitted to receive refractive surgery. During SMILE in the left eye, suction loss occurred at 65% of posterior cut completion. We switched to LASIK and SMILE was performed in the right eye as planned. The uncorrected 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.
Suction loss during SMILE is a rare complication. Good visual outcome was achieved by switching to LASIK.
