Abstract
BACKGROUND: Small incision lenticule extraction (SMILE) is popular among young myopic adults for long-term correction of myopia; however, the excessive axial lengths of myopic eyes and the associated risks for more serious eye diseases later on remain with surgical correction of the refractive error. These risks are greater the higher the myopia is. Are patients well informed about this and to what extent does further eye growth occur even after SMILE? MATERIAL AND METHODS: Myopic young adults who underwent binocular SMILE before 2019 were given the opportunity to have their eyes examined at a follow-up visit (biometry using IOL-Master 700 [Zeiss, Oberkochen, Germany], subjective refraction, examination of the anterior and posterior segments of the eye using the slit lamp) and to participate in a survey. Patients with a preoperative axial length ≥ 25.5 mm and a preoperative axial length < 25.5 mm (high myopia) were statistically evaluated separately. RESULTS: A total of 44 patients (age 30.39 ± 2.39 years) appeared at the visit and the SMILE was 3.18 ± 0.82 years ago: The spherical equivalent at the follow-up visit was -0.05 ± 0.21 dpt in the weaker myopes and -0.18 ± 0.23 dpt in the high myopes. Of the respondents 27% estimated that SMILE would reduce the risk of retinal detachment and cataract, with 80% of high myopes underestimating the individual risk of retinal detachment. Also, 57% said they would not see an ophthalmologist until within 1 week if they had symptoms consistent with acute retinal detachment, and only 27% would go to an emergency room immediately. In general, 59% reported having normal health awareness and 41% reported going for annual ophthalmological check-ups. CONCLUSION: The collected axial lengths and refractions show no relevant change in the eyes regarding progression of myopia; however, the patients' statements in the survey point out that most patients are not aware of the risk of serious eye diseases (retinal detachment, cataract). Therefore, repeated risk education and close postoperative care are needed, especially in preoperatively highly myopic patients.
