Purpose To evaluate the behaviour of the Micro AY 123 preloaded

IOL system during surgery and to report per-operative and post-operative outcomes in comparison to a previous study with the same lens implanted with a conventional micro-incision injector.

Methods Single centre, one surgeon Prospective study 32 eyes implanted with Micro AY Eyes examined at 1week, 3 months and 12 months Biaxial phaco: 1.3mm incision, enlarged to 1.7mm for IOL

The lens is packed in a micro-incision The lens is packed in a micro-incision cartridge. The injector is clipped to the cartridge. The injector is clipped to the cartridge and removed from the cartridge and removed from the container. After having placed container. After having placed viscoelastic behind the lens, the plunger viscoelastic behind the lens, the plunger is advanced slowly. The pressure is is advanced slowly. The pressure is slightly higher in the final stage, when slightly higher in the final stage, when the orange silicone cushion stretches in the orange silicone cushion stretches in the thinnest part of the injection tip.

Experience with Micro AY 123 preloaded system

10 lenses implanted Same incision size and implantation technique as

Micro AY with MicroSet injector (1.7mm) At 3 months:

20/20 BCVAGood lens centrationGood capsular transparency

ASCRS 2010ASCRS 2010

ConclusionMicro-incision lenses

Excellent visual outcomesLow level of induced astigmatism Low endothelial cells lossGood stability over timeGood maintenance of capsular bag transparency over

two yearsNo IOL-related complications

Micro-incision preloaded systemA promising alternative for a safer and more

reproducible injection
