POPULATION
42 patients (84 eyes)
Mean age 50 +/- 5 years
Patent presbyopia : addition +2.5 to +3 D
All of them expected independancy of spectacles
Lensectomy : december 2007 to december 2008
3 groups :
Bilateral diffractive Restor®AD1 (+3) (ALCON) = 20 eyes
Bilateral diffractive Restor®AD3 (+4) (ALCON) = 40 eyes
Mix-Match diffractive Tecnis ® (AMO) and in the
dominant eye refractive Rezoom ® (AMO) = 24 eyes
EVALUATION ( 5 +/- 1.5 months post-surgery)
Visual acuities
without correction, binocular
Distance, intermediate and near.
Quality of vision
Functional signs : dysphotopsy (halo, glare…), satisfaction rate
Contrast sensitivity (static, mesopic) +/- glare

DISCUSSION / litterature data
Deterioration of the quality of life when presbyopia appears
Luo BP, Brown MM. The quality of life associated with presbyopia. Am J Ophthalmol 2008
apr;145(4):618-622.
No way to recover acommodation but only to compensate it,
with unperfect results :
Spectacles / contact lenses
Presbylasik
Accommodative IOL / multifocal IOL
Mix-match requires neuro-adaptation but allows better visual
performances at all distance vision.

contralateral eye. J Refr Surg 2008 mar;24(3):300-5

CONCLUSION
Restor AD1 seems to give a better depth of focus compared
with Restor AD3 and better visual performances than MixMatch implantation.
Further investigations have to be driven , increasing the
number of patients and including other methods for
presbyopia compensation or restoration.
Specific care required for patients selection , according to
preoperative ametropia and to their way of life , in order to
select the best « custom implantation »
