Complications can occur with refractive lenticule extraction (ReLEx) procedures, including femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SMILE). Most issues are linked to surgeon inexperience and typically resolve without impacting final visual acuity.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Refractive lenticule extraction (ReLEx) encompasses two techniques: femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SMILE).
  • Understanding the complication profile of these refractive surgery modalities is crucial for patient safety and surgical outcomes.

Purpose of the Study:

  • To document and analyze the complications encountered in both FLEx and SMILE procedures.
  • To evaluate the frequency and types of complications associated with ReLEx surgery.

Main Methods:

  • A retrospective review of consecutive clinical cases undergoing ReLEx FLEx or SMILE procedures.
  • Inclusion criteria focused on patients experiencing complications.
  • Data collected included demographics, complication type, and final visual and refractive outcomes.

Main Results:

  • The study included 94 eyes (FLEx) and 160 eyes (SMILE) with a mean 36-month follow-up.
  • FLEx complications occurred in 18.3% of eyes (suction loss, bubbles, misdissection).
  • SMILE complications occurred in 26.9% of eyes (epithelial defects, opaque bubble layer, cap/lenticule rupture).

Conclusions:

  • Complications associated with ReLEx surgery are possible but often manageable.
  • The majority of complications are attributed to surgeon inexperience.
  • Favorable resolution with no long-term visual acuity impairment is typical for most ReLEx complications.
