Hubble Trouble: Repairing the Hubble Space Telescope

The first images produced by the Hubble Space Telescope were fuzzy and unclear due to a problem with its optical system. While the media had a field day with this “Hubble Trouble,” NASA had an opportunity to prove that they could fix the telescope in orbit, a task that was uniquely incorporated into the Hubble’s design. Astronauts were able to repair the telescope, and soon after, the Hubble Space Telescope was producing stellar images.

This doesn't explain how they repaired it with corrective lenses.
