Knowledge, attitudes, and practices toward femtosecond laser small incision lenticule extraction surgery and postoperative care among recipients

Abstract

BackgroundTo investigate the knowledge, attitudes, and practices (KAP) of individuals who underwent small incision lenticule extraction (SMILE) surgery and explore the influencing factors.MethodsThis cross-sectional study was conducted from June 21, 2023, to August 13, 2023, at Xiangyang Central Hospital. The participants were patients who had undergone SMILE surgery. The self-designed questionnaire had a Cronbach’s α = 0.849. Multivariable analyses were performed to determine the factors influencing the KAP scores.ResultsFinally, 485 valid questionnaires were analyzed. The median knowledge score was 14 (/17, 82.4%; IQR: 12–15). The median attitude score was 15 (/20, 75.0%; IQR: 14–16). The median practice score was 48 (/60, 80.0%; IQR: 42–54). The knowledge scores correlated to the attitude (r = 0.323, P < 0.001) and practice (r = 0.202, P < 0.001) scores, while the attitude scores correlated to the practice scores (r = 0.065, P < 0.001). College diploma (OR = 0.299, 95%CI: 0.110–0.812, P = 0.018), myopia for < 2 years (OR = 0.177, 95%CI: 0.060–0.526), and not receiving proper eye training (OR = 0.588, 95%CI: 0.402–0.862) were independently associated with knowledge. Being 19–30 years old (OR = 0.421, 95%CI: 0.235–0.756), being ≥ 31 years old (OR = 0.259, 95%CI: 0.111–0.601), myopia for 2–5 years (OR = 0.476, 95%CI: 0.232–0.978), myopia for 5–10 years (OR = 0.480, 95%CI: 0.263–0.875), and moderate myopia in the right eye (OR = 1.745, 95%CI: 1.024–2.974) were independently associated with attitude. Female gender (OR = 1.826, 95%CI: 1.196–2.787), being ≥ 31 years (OR = 2.587, 95%CI: 1.113–6.014), college diploma (OR = 3.436, 95%CI: 1.366–8.641), bachelor’s degree (OR = 2.826, 95%CI: 1.214–6.581), and not having proper eye training (OR = 0.458, 95%CI: 0.310–0.677) were independently associated with practice.ConclusionsPatients who underwent SMILE had high KAP regarding SMILE. This study identified KAP items that would warrant education.
