Genoa, Italy, June, 2009, /Journal of Refractive Surgery/
-- A long-term follow-up of patients who had Photorefractive Keratectomy
(PRK) in the early 1990's affirms a long-held belief that PRK is
stable and safe for patients with myopia - nearsighted vision.
Evaluation of the health of the eyes and the stability of the
changes made during PRK indicates the laser vision correction method
provides good results for people with low to moderate myopia under
6.00 diopters and high myopia over 6.00 diopters, although a remarkable
difference in patient satisfaction was noted. While 84% of the PRK
patients with moderate to low myopia remain satisfied with the results,
a lesser 75% of the high myopia group indicated satisfaction in
a subjective questionnaire.
The study is authored by Graziano Bricola, MD, of the Centro
di Ricerca Clinica e Laboratorio per il Glaucoma e la Cornea – Clinica
Oculistica, Di.N.O.G., University of Genoa, Azienda Ospedaliera
Universitaria San Martino, Genoa, Italy, who has been following a group
of 31 patients (49 eyes) who underwent PRK between 1991 and 1993.
