Purpose

• To study refractive and visual outcomes of
  central presbylasik technique (PresbyMax), based
  on the creation of a central area for near vision
  (2 D of addition), in myopic patients.

4
Patients

• Study design Prospective, non comparative pilot
  study that included a total of 42 myopic eyes
  with age between 40 and 56 years.
• Inclusion criteria myopia 4 (D), astigmatism 2
  (D), corneal curvature between 40 and 48 D,
  pachymetry gt500, and near vision of J3 with
  addition of 1.50 D.

5
Methods

• The ablation pattern was performed using the
  Esiris excimer laser (Schwind, Frankfurt,Germany),
  centred in corneal vertex and biaspheric
  profile.
• The main outcome measures were refraction,
  uncorrected and best corrected visual acuities
  for near and distance, corneal aberrations
  (spherical and coma) and patient satisfaction.

6
Results spherical equivalent
At 6 months after surgery, the spherical
equivalent refraction was 0.210.37 (D).
7
Visual acuity
The distance decimal visual acuity with without
correction 0.880.14.
8
Visual acuity
Mean near decimal visual acuity without
correction 0.930.25.
Mean near distance corrected decimal visual
acuity was 0.530.26.
9
Addition
The addition change from 1.3 preop to 0.88D after
6 months postoperative.
10
Results Corneal aberrations

• Spherical corneal aberrations showed a trend
  towards positive increase while coma corneal
  aberration did not change.

11
Conclusions

• Central presbylasik with biaspherical profile may
  be used to improve functional near vision in
  patients with presbyopia associated with low to
  moderate myopia.
• 70 of patients could dispense with the use of
  glasses both for far and near 6 months after the
  surgery.
