Purpose
To analyze visual, refractive and subjective outcomes following Presbyond Laser Blended Vision (Carl Zeiss Meditec) treatment using non-linear aspheric micro-anisometropia femtosecond LASIK for the correction of myopia (with or without astigmatism) and presbyopia.
Setting
Lexum Eye Clinics (Brno / Prague, Czech Republic), Optegra Group
Methods
Study of 80 consecutive eyes of 40 patients with myopia (-0.5 to -7.5 D) and astigmatism ( 0 to -2.25 D), who underwent Presbyond using femtosecond laser VisuMax and excimer laser MEL 90 (Carl Zeiss Meditec). A mean age of the study group was 50.48 ± 4.27 years (44 to 60 years). Distance and near visual acuity as well as subjective refraction were examined. Higher order aberrations (HOAs) were assessed using wavefront-aberrometer Peramis (Schwind). A questionnaire evaluating outcomes and satisfaction was completed by patients. The target refraction was plano for distance eyes (dominant eyes) and between −0.75 and −1.50 D for near eyes (nondominant eyes). Patients were examined before surgery and at 1 months and 3 months after surgery.
Results
Mean preoperative spherical equivalent (SE) was −3.94 ± 1.82 D (−0.5 to −8.0 D). Mean postoperative SE of distance eyes was +0.22 ± 0.32 D (−0.38 to +1.00 D), mean postoperative SE of near eyes was −0.82 ± 0,41 D (0 to −1.5 D). 100% of eyes had SE within ±1.00 D of intended refraction. Mean binocular uncorrected distance visual acuity (UDVA) was 1.23 ± 0.2 (1.0 to 1.5), mean binocular uncorrected near visual acuity (UNVA) was 0.84 ±0.21 (0.32 to 1.0). 100% of distance eyes achieved UDVA of 0.7 or better, and 80% of near eyes achieved UNVA of 0.5 or better. The spherical aberration of the eyes (for a 6-mm pupil) was 0.13 ± 0.11 µm before surgery and 0.28 ± 0.29 µm in the dominant eye and 0.20 ± 0.26 µm in the nondominant eye after surgery.
Conclusions
Presbyond Laser Blended Vision has shown very good efficiency and safety for the correction of presbyopia combined with myopia (with or without astigmatism). Despite some patient´s complaints related to relatively poorer near vision, all patients were satisfied with or accepted the outcomes of the surgery.
