Do I really need an implant?

In the vast majority of cases yes. Only in people who are severely nearsighted before the surgery your doctor may not recommend an implant. If an implant (IOL) is not used the eye will have no lens, and just like a camera without a lens things will be very blurry. You would need to wear a contact lens or very thick glasses to see clearly.

What is the implant made out of?

Three materials are currently commonly used to manufacture implants: polymethylmethacrylate (PMMA), silicone and acrylic. PMMA has been used the longest - it is similar to the plastic in crazy glue. Silicone and acrylic lenses are flexible and can be rolled up so they can be placed in the eye through a smaller opening.

Once in the eye they unroll and placed in their proper location. In contrast, PMMA lenses are stiff, and require a larger opening in the eye to introduce the implant.

Does the implant stay in my eye? Will it fall out?

The implant is seated in the eye so that it will remain in place.

How long is it good for?

The rest of your life.
