MİYOPİ VE MİYOPİK ASTİGMATİZMA TEDAVİSİNDE UYGULANAN PRK VE FS-LASİK PROSEDÜRLERİNİN KIYASLANMASI

Amaç: Miyopi ve miyopik astimatima tedavisinde uygulanan fotorefrakti keratektomi (PRK) ile Femtosaniye Lazer in situ keratomileusis (FS-LASIK) prosedürlerinin sonuçlarının kıyaslanması. Gereç ve Yöntem: Miyopi ve/veya miyopik astimat olan ve PRK prosedürü uygulanan 57 hastanın 114 gözü ile, FS-LASİK uygulanan 57 hastanın 114 gözü retrospekti olarak kıyaslandı. Bulgular: İki grup arasında yaş ve cinsiyet açısından anlamlı bir farklılık yoktu. Yine iki grup arasında preoperati ve postoperati sferik değer, slendrik değer ve sferik eşdeğer, düzeltimemiş görme keskinliği ve düzeltimiş görme keskinliği açısından anlamlı bir farklılık yoktu. Öngörülebilirlik, etkinlik ve güvenilirlik endeks değerleri her iki grupta yüksekt 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 istatitii olarak anlamlı değildi. Sonuç: Miyopi ve miyopik astimatima tedavisinde , hem PRK hem de FS-LASİK etkin, güvenilir ve öngörülebilir prosedürlerdir. Yüksek dioptrilerde PRK uygulanan gözlerde haze ve regresyon gelişebilir.

Comparison of PRK and FS-LASIK Procedures in Treatment of Myopia and Myopic Astimatim

Aim: To compare the results of photorefractie keratectomy (PRK) and femtosecond-assisted laser in situkeratomileusis (FS-LASIK) procedures in treatment of myopia and myopic astimatim.Material and Methods: One hundred and fourteen eyes of 57 patints with myopia and/or myopic astimatimwho had undergone PRK procedure were compared retrospectiely with 114 eyes of 57 patints with myopiaand/or myopic astimatim who had undergone FS-LASIK procedure.Results: In respect to age and sex, there were no signifiant diffrences between PRK and FS-LASIK groups.Regarding preoperatie and postoperatie spherical, cylinderical and spherical equivalent values, uncorrecteddistance visual acuity (UDVA) and corrected distance visual acuity (CDVA), there were no signifiant diffrencesbetween two groups. Predictability, efficy and safety index values were high and similar in both groups. Hazedeveloped in two eyes in PRK group, but they recovered 6 months later and regression occured up to -1.00 Din three eyes in PRK group. However, these were not signifiant statitially.Conclusion: Both PRK and FS-LASIK are effient, safe and predictable procedures for correctin of myopia andmyopic astimatim. PRK may induce haze and regression in high diopters.
