you need to see an ophthalmologist. This could be Marcus-Gunn Jaw Winking syndrome see http://emedicine.medscape.com/article/1213228-overview or it could be blepharospasm.
See and Eye MD ophthalmologist soon.

For the past several months my muscle or nerve under my right eye spasms.this happens pr when I speak or lets say chew.people can actually see the twitch.my left eye doesnt twitch however when I squint you can clearly see the muscle moves .I also noticed the skin has become thinner.this differs form my ocassional spasms that happen at random. any advice:?
It is highly unlikely that you have a bad IOL as in almost all of the world they are manufactured to high standards. Also you should be talking about your vision wearing the best glasses possible. Often good vision comes only when wearing glasses.
There could be other problems in the eye like age related macular degeneration. Suggest you get a second and third opinion from ophthalmologists outside of the one that did your surgery.
