Overview

Observational analysis showed changes in tear film and visual acuity in patients after refractive surgery, indicating potential dry eye complications.

Key Points

  • Postrefractive surgery patients exhibited a decrease in tear break-up time and visual acuity.
  • Tear secretion measured by the Schirmer I test revealed significant changes at multiple follow-up intervals.
  • Changes in ocular surface status were observed as significant indicators of dry eye syndrome following surgery.
  • Some patients experienced persistent dry eye symptoms beyond 6 months postoperatively.
