Abstract PDF ePub: Purpose
This study reports a case of a large incisional tear caused by abrupt Bell’s phenomenon during pocket irrigation in femtosecond laser-assisted small incision lenticule extraction (SMILE).
Case
summary: A 28-year-old male patient underwent SMILE surgery. During pocket irrigation of the right eye, Bell’s phenomenon suddenly occurred, resulting in a large inferior arcuate extension of the incision that reached the inferior cap margin. After confirming wound integrity and the absence of additional tissue damage, a bandage contact lens was applied. On postoperative day 7, the incision was self-sealed with intact wound integrity. Three months postoperatively, uncorrected distance visual acuity was 20/20 in both eyes. The right cornea remained stable, although a faint residual scar was observed at the site of the incisional tear.
Conclusion
Abrupt eye movements during pocket irrigation in SMILE can cause large incisional tears. Surgeons should exercise heightened vigilance during irrigation, particularly in anxious or uncooperative patients, to prevent such complications.
