The slight optical defect (known as a spherical aberration, and less than 4 microns, 1/5 the thickness of a human hair) discovered in the Hubble's primary mirror after it was deployed in space, was corrected by a system known as COSTAR (Corrective Optics Space Telescope Axial Replacement). Built by Ball Aerospace, it was manufactured and tested between the Hubble's first deployment and her First Servicing Mission in 1993.
COSTAR (since replaced, as all Hubble instruments installed after the FSM have corrective optics) worked much like corrective eyeglasses, using a system of tiny mirrors to correct for the flaw. The result of COSTAR's installation (and all of us who worked on it waited with our breath held until it was operational and the first pictures were in) was nothing less than spectacular, restoring Hubble to its original design specifications.
