ÖZET

Amaç: Miyopi ve miyopik astigmatizma tedavisinde uygulanan fotorefraktif keratektomi (PRK) ile Femtosaniye

Lazer in situ keratomileusis (FS-LASIK) prosedürlerinin sonuçlarının kıyaslanması.

Gereç ve Yöntem: Miyopi ve/veya miyopik astigmatı olan ve PRK prosedürü uygulanan 57 hastanın 114 gözü

ile, FS-LASİK uygulanan 57 hastanın 114 gözü retrospektif olarak kıyaslandı.

Bulgular: İki grup arasında yaş ve cinsiyet açısından anlamlı bir farklılık yoktu. Yine iki grup arasında preoperatif

ve postoperatif sferik değer, slendrik değer ve sferik eşdeğer, düzeltilmemiş görme keskinliği ve düzeltilmiş

görme keskinliği açısından anlamlı bir farklılık yoktu. Öngörülebilirlik, etkinlik ve güvenilirlik endeks değerleri

her iki grupta yüksekti ve benzerlik göstermekteydi. PRK grubunda iki gözde haze gelişti, ancak bu gözler 6 ay

sonra düzeldi, ve üç gözde -1.00 D ye kadar regresyon gelişti. Ancak bunlar istatistiki olarak anlamlı değildi.

Sonuç: Miyopi ve miyopik astigmatizma tedavisinde , hem PRK hem de FS-LASİK etkin, güvenilir ve öngörülebilir

prosedürlerdir. Yüksek dioptrilerde PRK uygulanan gözlerde haze ve regresyon gelişebilir.

Anahtar kelimeler: PRK; FS-LASİK; Haze; Regresyon

ABSTRACT

Aim: To compare the results of photorefractive keratectomy (PRK) and femtosecond-assisted laser in situ

keratomileusis (FS-LASIK) procedures in treatment of myopia and myopic astigmatism.

Material and Methods: One hundred and fourteen eyes of 57 patients with myopia and/or myopic astigmatism

who had undergone PRK procedure were compared retrospectively with 114 eyes of 57 patients with myopia

and/or myopic astigmatism who had undergone FS-LASIK procedure.

Results: In respect to age and sex, there were no significant differences between PRK and FS-LASIK groups.

Regarding preoperative and postoperative spherical, cylinderical and spherical equivalent values, uncorrected

distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), there were no significant differences

between two groups. Predictability, efficacy and safety index values were high and similar in both groups. Haze

developed in two eyes in PRK group, but they recovered 6 months later and regression occured up to -1.00 D

in three eyes in PRK group. However, these were not significant statistically.

Conclusion: Both PRK and FS-LASIK are efficient, safe and predictable procedures for correction of myopia and

myopic astigmatism. PRK may induce haze and regression in high diopters.

Keywords: P-PRK; FS-LASIK; Haze; Regression
