PRK versus LASIK for correction of moderate Myopia -2 bis -7,75 D
Gießler S., Duncker G. I. W.
Klinik und Poliklinik für Augenheilkunde, Martin-Luther-Universität, Halle/Saale
Background: We studied the visual outcome of excimer laser photorefractive
keratectomy (PRK) and laser in situ keratomileusis for the correction
of moderate myopia, especially the safety (lost of 1 line) and efficacy
(postoperative spherical equivalent (SE) refraction between +/- 1 D.
Methods: 61 eyes with preoperative SE from -1.5 to -7.75 D underwent
LASIK (Keracor 217, Technolas, Bausch & Lomb). 30 eyes with SE from
- 1.8 to -7.5 D underwent PRK (Keracor 217 and MEL 70, Aesculap, Meditec).
Results: After half a year 57% of the eyes of the LASIK group and
57% of the PRK group achieved the attempted bestcorrected visual acuity
like preoperativly. 27% (LASIK) and 23% (PRK) gain 1 to 2 lines. 13% (LASIK)
and 10% (PRK) lost 1 line. 3% (LASIK) and 10% (PRK) lost 2 lines. 86%
(LASIK) and 90% (PRK) achieved a postoperative SE of +/- 1D.
Conclusions: There are no differences in efficacy between both
surgical techniques. There is a little but insignificant difference in
loosing 2 lines. The faster visual rehabilitation and the minimal pain
are the advantages of LASIK even for moderate myopia.
