this has been the scene on the streets of Santiago, Chile.

Protesters say they're fed up with growing inequality.

Most come out in peace but they're met with force,

and the situation quickly escalates.

Chile is supposed to be one of Latin America's more

stable democracies, a model for success since the country's

dictatorship ended in 1990.

But this brutal crackdown suggests

the security tactics haven't changed all that much.

Police have fired pellets and rubber bullets.

These rounds are often shot at close range, hitting people

where they can do maximum damage: the eyes.

More than 180 protesters have been partly blinded.

And the numbers continue to rise.

I follow Carlos Puebla

into the eye trauma unit of a public hospital.

The waiting room is full of people

who tell me a similar story.

I'm back with Carlos Puebla.

Dr. Carmen Torres,

who removed his eye several days ago,

tries to insert an implant.

But the pain is too intense.

Dr. Enrique Morales is tracking

what doctors see here as an epidemic of eye trauma.

The government denies any wrongdoing.

Later, my official request to the minister and to the police

were also declined.

International human rights groups

are investigating allegations of abuse.

But that process rarely succeeds

in bringing the powerful to account.

After all, it was Chile's president, Sebastian Piñera,

who set the stage for the violent clampdown.

Since then, at least five deaths,

more than 180 severe eye injuries,

1,800 hospitalizations,

5,000 arrests,

plus allegations of torture

and sexual violence.

Many of the victims say they were not acting aggressively

when they were shot.

All they can do now is file a lawsuit and wait.

The police violence hasn't deterred people

from coming out — to the contrary.

A few days after I met him in the hospital

Pablo Verdugo is back on the streets,

taking care to protect his face and eyes from tear gas.
