| Popis: | PURPOSE: To report 1-year visual and refractive outcomes following PRESBYOND Laser Blended Vision using non-linear aspheric micro-monovision with the MEL 90 platform (Carl Zeiss Meditec GmbH). METHODS: Data were collected retrospectively for all patients who underwent treatment for simultaneous correction of refractive error and presbyopia from June 2015 to June 2018. Only those patients who completed at least 6 months of follow-up were included in the study. RESULTS: A total of 101 patients with a mean age of 51.05 ± 5.15 years (range: 40 to 65 years), of whom 38 patients had myopic and 63 patients had hyperopic refractive error with or without astigmatism, were included in the study. Mean preoperative spherical equivalent was −3.36 ± 1.86 diopters (D) in the myopia group and +1.75 ± 0.99 D in the hyperopia group. At 1 year, the mean spherical equivalent refraction was +0.13 ± 0.32 D in the distance eye and −1.42 ± 0.33 D (range: −0.88 to −2.50 D) in the near eye in the myopia group and −0.13 ± 0.24 D in the distance eye and −1.28 ± 0.31 D (range: −0.63 to −2.00 D) in the near eye in the hyperopia group. Two eyes in the hyperopia group underwent early enhancement for the near eye at 3 months. Ninety-seven percent of the patients in the myopia group and 96% in the hyperopia group were satisfied with their distance vision. Near vision satisfaction score was 95% for the myopia group and 89% for the hyperopia group. CONCLUSIONS: At 1 year, the aspheric micro-monovision protocol resulted in satisfactory and fairly stable visual outcomes in both myopic and hyperopic individuals.
