ABSTRACT
Refractive surgery, from keratomileusis to laser-assisted in situ keratectomy (LASIK), have sequentially offered the promise of permanently correcting refractive visual errors. However, as these procedures have gained initial acceptance and then wider application, invariably problems have been encountered, ranging from regression and reduced visual acuity to progressive corneal instability that ultimately limit the successfulness of these procedures, seemingly leaving unfulfilled the promise of perfectly corrected vision.
