2. MI60 - SALIENT FEATURES IOL Design Material : hydrophilic acrylic
Inert
Biocompatible
Good centration
Good in the bag stability
Foundation zone
IOL Design
Formed by the optic and the haptic base
Stable portion of the lens
Bends under the contraction forces of the capsular bag
Foundation zone
The features of the material used for the Akreos AO Micro Incision Lens are shown on the slide.
The 26% water content acrylic material makes the lens highly injectable.
Absorption zone
Absorption zone 2

3. MI60 - SALIENT FEATURES Design: optic Design: haptic
Suitable for sub-2 mm injection without compromising quality of vision
aspheric aberration-free optic
360° posterior barrier and square-edge design
moderate refractive index
30% thinner than parent design
3D-deformable four-point haptics are the next generation haptic design seen in Akreos AO Micro Incision Lens only
Provide consistent three-dimensional stability
capitalizes on stability features of parent designs
four-point capsular bag fixation with three overall diameters
overall diameter varying with diopters
average 10° angulation
innovative haptic shape

4. STUDY DESIGN DEMOGRAPHICS: 250 EYES OF 177 PATIENTS
APR 2007 TO OCTOBER 2008
FOLLOWUP
MAX 20 MONTHS
MIN 3 MONTHS
MICS was performed by a single experienced surgeon with
NO SURGERY RELATED COMPLICATIONS

5. Preoperative evaluation
Postoperative Analysis
Visual acuity < 6/12
Keratometry < 1 D of astigmatism
IOL Master
Complete ophthalmic evaluation
Visual acuity
Surgically induced astigmatism
Contrast sensitivity
Centration
biocompatability

6. RESULTS
BCVA = 6/6, N6 IN 238
EYES (95%6/9, N6 IN
18 EYES (7%)

7. INDUCED ASTIGMATISM IN DIOPTERS
INDUCED ASTIGMATISM SMICS : 0.00D TO 0.50D (Avg 0.30)
INDUCED ASTIGMATISM CONVENTIONAL PHACO : 0.50D TO 1.50D (Avg 1.00)
No. OF EYES : 250
INDUCED ASTIGMATISM IN DIOPTERS

8. CONTRAST SENSITIVITY Tested using SLOAN letters of decreasing contrast
Distance-1m
In both PHOTOPIC and MESOPIC conditions
MI60 LENS

9. PHOTOPIC CONDITIONS
Using 85-candles/ sq meter, the Akreos MI60 lens showed marginal improvement of 28% in the contrast sensitivity over other IOLs
Akreos MI60
SA60

10. MESOPIC CONDITIONS
Akreos AO MI60
SA60
Using 1 candle / sq meter, the Akreos MI 60 lens had a contrast function of 34%

11. Good centration and biocompatibility
AKREOS AO MI60 LENS
POST-OP : DAY 1
POST-OP : 1 MONTH
Good centration and biocompatibility
