OBJECTIVE 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.

UI MeSH Term Description Entries
D006956 Hyperopia A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed) Farsightedness,Hypermetropia
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009216 Myopia A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness. Nearsightedness,Myopias,Nearsightednesses
D011305 Presbyopia The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation. Presbyopias
D011795 Surveys and Questionnaires Collections of data obtained from voluntary subjects. The information usually takes the form of answers to questions, or suggestions.

D012029 Refraction, Ocular Refraction of LIGHT effected by the media of the EYE. Ocular Refraction,Ocular Refractions,Refractions, Ocular
D005260 Female Females
D005500 Follow-Up Studies Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.
