The author of this poster has received travel expense reimbursement from B&L
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.
ASCRS 2010ASCRS 2010
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
implantation Endothelial cells count, astigmatism, visual acuity, IOL
centration, IOL surface state, anterior segment aspect, posterior capsule aspect and complications

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. The the thinnest part of the injection tip. The lens unfolds gently and is perfectly intact lens unfolds gently and is perfectly intact after injection.after injection.
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
