Purpose: To report the factors affecting visual outcomes after small incision lenticule extraction (SMILE) in eyes treated with the Visumax 800. Methods: This is a retrospective study with cross-sectional design of eyes underwent SMILE Pro using Visumax 800 at Jakarta Eye Center. Patients ≤40 years old with a corrected distance visual acuity of >20 / 25, manifest refractive spherical equivalent ≤10.0 diopters (D), and cylinder refraction <5.0 D were included. Evaluation of visual outcomes was conducted at 1 day and 1 month postoperatively. Results: A total of 258 eyes from 132 patients were analyzed. Among the total, 94% achieved an uncorrected distance visual acuity (UDVA) of 20 / 20 at 1 month postoperatively. Of the eyes with high myopia, 81% achieved a UDVA of 20 / 20, followed by 97% and 99% in moderate and low myopic eyes, respectively. Spherical equivalent refraction (r = 0.273, p < 0.01), optic zone (OZ; r = 0.260, p < 0.01), cap thickness (r = 0.209, p < 0.01), and residual stromal thickness (RST; r = 0.256, p < 0.01) showed a significant but weak correlation with UDVA at 1 month postoperatively. There is increasing risk to get <20 / 20 UDVA in right eyes (odds ratio [OR], 3.101; p < 0.045), eyes with high myopia (OR, 9.964; p < 0.01), 100-μm cap thickness (OR, 4.578; p < 0.01), ≤6 mm OZ (OR, 10.556; p < 0.01), and <300-μm RST (OR, 9.100; p < 0.01) at 1 month postoperatively. Conclusions SMILE Pro results in promising visual outcome in early postoperative period. Patients with low to moderate myopia have better visual outcomes than those with high myopia. A small OZ, thin cap thickness, and low RST could increase the risk of not achieving the maximum visual outcome after SMILE. A prospective study with a longer follow-up period that includes comprehensive variables is needed to fully understand the factors affecting visual acuity after SMILE.

EDUCATIONAL EXPERIENCES, ATTITUDE AND PRACTICE OF RESIN INFILTRATION AMONGST MALAYSIAN PEDIATRIC DENTAL SPECIALIST & POST-GRADUATE STUDENTS: A PRELIMINARY STUDY Objectives: (i) To evaluate the educational experiences, attitude and practice of resin infiltration (RI) amongst Malaysian Paediatric Dental Specialists and post-graduate students (ii) to determine the relationship between their educational experiences and attitude in the practice of RI in children. Material & Methods: This cross-sectional study used a self-administered questionnaire distributed online to Malaysian Association of Paediatric Dentistry (MAPD) members from December 2022 to February 2023. Demographics, educational experiences, attitudes, and RI use were measured. Descriptive data, Cronbach alpha coefficient, and Pearson correlation tests were obtained. Results: Out of the 110 invited members, 30 surveys were completed, with a response rate of 27.3%. The knowledge subscale comprised 19 items (α=0.84), and the attitude/practice subscale had 11 items (α=0.77). A total of 46.7% agreed that their undergraduate training had prepared them well to use RI with paediatric patients. 93.4% of respondents felt their training in paediatric graduate programs had informed and adequately prepared them for RI usage. Most respondents expressed interest in learning more about RI (100%) and attending continuing education course (93.3%). The respondents positively viewed RI, especially its aesthetic benefit (100%). Only 16.7% of respondents used RI frequently, while others used it rarely (63%) or never (20%). There was no correlation between education experiences and attitude in using RI (r=0.14: p<0.46). Conclusion: While the correlation was not significant, this study showed the need to incorporate RI into the dental curriculum. Hence, expanding undergraduate, postgraduate, and continuing professional education in RI should be strengthened.
