title: [Laser Blended Vision for presbyopia: Results after 3 years].
abstract: OBJECTIVE
  Retrospective study of the first 173 patients with presbyopia who underwent LASIK with a non-linear aspheric ablation profile and micro-monovision for the correction of presbyopia with myopia, astigmatism, hyperopia or emmetropia: Laser Blended Vision(®) Program by Carl Zeiss Meditec(®) (Jena, Germany).
  
  
  METHODS
  We retrospectively studied the first consecutive 173 patients with presbyopia who underwent LASIK with the wavefront-guided Laser Blended Vision(®) Program by Zeiss(®) in our Excimer Laser Zeiss Mel-80 by Carl Zeiss Meditec(®) (Jena, Germany) over the last three years in our clinic (Optima Laser Clinic, Valence, Spain). The program has a non-linear aspheric ablation profile that increases the spherical aberration in both eyes. A slight myopia of -1.5 diopters (D) in the non-dominant eye is also programmed. We analysed the results and patient satisfaction. The patients were separated into two groups: less than 50 years old and 50 years or more. Follow-up was from 1 to 28 months. We also separated two groups: follow-up under 12 months and follow-up of 12 months or more. We analysed the efficacy, safety and predictability of the procedure.
  
  
  RESULTS
  Seventy-nine male and 94 female patients between 42 and 69 years old were studied, for a total of 337 eyes. Only eight patients (4.62%) were between 42 and 44; 55 (31.79%) were between 45 and 49; 110 patients (63.58%) were 50 years or more. Nine patients underwent the surgery in the non-dominant eye only. Twelve (6.94%) patients were emmetropic (0.5 or less spherical equivalent), 42 (24.28%) were myopic or myopic astigmatic, and 119 (68.79%) were hyperopic or hyperopic astigmatic. One hundred and thirty-six patients (78.61%) had pre-operative near vision between J4 and J10. One hundred and seventy-one patients (98.84%) had post-operative near vision between J1 and J3; 150 (86.7%) had J1 (efficacy). Post-operative visual acuity without correction for distance was 20/20 or better in 159 patients (91.91%) (binocular). The predictability within 0.5 D was 87.86%. Safety 99.7% (336/337 eyes): one eye of a diabetic patient lost two lines BCVA. A total of 93.64% were satisfied with the procedure, 2.89% used eye-glasses for certain activities, 1.73% reported dry eye, 0.58% reported a nonspecific lack of adaptation, and there were no serious complications; 3.47% did not achieve their expectations. Twenty-four patients (13.87%) needed an enhancement, 18 of them (75.5%) for only one eye, with 88.89% of these being the non-dominant eye. Forty-nine patients (28.32%) had over 12 months follow-up, with 95.92% still satisfied.
  
  
  CONCLUSIONS
  Laser Blended Vision(®) is an excellent option, well tolerated, stable and effective for patients with presbyopia and myopia, astigmatism, hyperopia or emmetropia, also avoiding an intraocular procedure.
