ClinConnect Summary

The study enrolled 113 highly myopic patients (202 eyes) who underwent SMILE surgery at Shanghai's Tenth People's Hospital. Patients were classified into three groups based on the axial length before surgery: Group A (AL \< 26 mm, 62 eyes), Group B (26 mm ≤ AL \< 27 mm, 88 eyes), and Group C (AL ≥ 27 mm, 52 eyes). Preoperative and postoperative evaluations included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), equivalent spherical error(SE), and corneal high order aberration. Subjective visual quality was assessed using the Quality of Vision (QoV) quest...
