PRK, or photorefractive keratectomy, is safe for the correction of both low myopia and high amounts of nearsightedness, according to a long-term follow-up study of the procedure. Researchers in Italy followed 31 patients who underwent either unilateral or bilateral PRK in 1991 to 1993. A total of 49 nearsighted eyes were included in the study, and check-ups were performed every two years over a period of 14 years.

Wavefront-guided LASIK induces fewer higher-order aberrations than wavefront-optimized LASIK
June 1, 2009A recent study finds wavefront-guided LASIK induces fewer higher-order aberrations than a related customized laser vision correction procedure called wavefront-optimized LASIK. Typically, fewer higher-order aberrations means better visual outcomes after LASIK surgery. The study suggests wavefront-guided LASIK offers the best results for most patients, with a lower incidence of re-treatments.
