简要总结
This retrospective study aimed to investigate the subjective and objective visual outcomes following Small Incision Lenticule Extraction (SMILE) surgery in high myopic patients with varying axial lengths (AL).
详细描述
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) questionnaire.

结局指标
主要结局
Subjective visual quality
时间窗: 12 months
The quality of vision (QOV) questionnaire consists of (i) symptom frequency, (ii) severity, and (iii) bothersomeness for (a) glare, (b) halo, (c) starbursts, (d) hazy vision, (e) blurred vision, (f) distortion, (g) multiple images, (h) visual fluctuations, (i) difficulty focusing, and (j) difficulty judging distance or depth perception. Respondents use a scale of 0 to 3, where zero (0) denotes "none," one (1) "a little," two (2) "quite a bit," and three (3) "very much." Furthermore, on a scale from 0 to 10, patients were asked to provide Likert ratings for "daytime" and "nighttime" quality of vision (0 denoting the poorest vision, while 10 indicating the best vision)
