COMPARISON OF THE TARGET REFRACTIVE VALUE AND THE RESULTING REFRACTIVE VALUE IN PATIENTS UNDERGOING PHACOEMULSIFICATION SURGERY

Abstract

Objective: To evaluate the target refractive value before and after surgery in patients who underwent phacoemulsification surgery. Material and Method: Patients diagnosed with cataracts who underwent surgery between January 2015 and March 2017 in the Department of Ophthalmology in Istanbul University’s Faculty of Medicine were accepted in this study. The difference between the target refractive value and the resulting refractive value was recorded as a refractive error. Results: 150 eyes of 107 patients were accepted and used in this study. The SRK-T formula was applied to 100 eyes and the SRK-2 formula were applied to 50 eyes. The mean targeted refractive value was -0.21±0.17 D in the SRK-T formula group and -0.22±0.29 D in the SRK-2 formula group. The mean resulting refractive value was -0.19±0.37 D in the SRK-T formula group and -0.12±0.77 D in the SRK-2 formula group. The mean refractive error was 0.2±0.25 D in the SRK-T formula group and 0.51±0.59 D in the SRK-2 formula group. The difference between the two groups was statistically significant (p=0.001). Conclusion: The SRK-T formula gave results which were significantly closer to the refractive target than the SRK-2 formula.

FAKOEMÜLSİFİKASYON CERRAHİSİ YAPILAN HASTALARDA HEDEF REFRAKTİF DEĞER İLE SONUÇ REFRAKTİF DEĞERİN KARŞILAŞTIRILMASI

Abstract

Amaç: Fakoemülsifikasyon cerrahisi uygulanan hastalarda cerrahi öncesi hedeflenen refraktif değer ile cerrahi sonrası ortaya çıkan sonuç refraktif değerin karşılaştırılması. Gereç ve Yöntem: Katarakt tanısı ile Ocak 2015- Mart 2017 arasında İstanbul Üniversitesi İstanbul Tıp Fakültesi Göz Hastalıkları biriminde cerrahi uygulanan hastalar çalışmaya alındı. Cerrahi öncesi hedeflenen refraktif değer ile cerrahi sonrası ortaya çıkan sonuç refraktif değer arasındaki fark refraktif hata olarak kaydedildi. Bulgular: 107 hastanın 150 gözü çalışmaya alındı. 100 gözde SRK-T, 50 gözde SRK-2 formülü kullanıldı. Ortalama hedeflenen refraktif değer SRK-T formülü uygulanan grupta -0,21±0,17 D, SRK-2 formülü uygulanan grupta -0,22±0,29 D idi. Cerrahi sonrası ortalama refraktif değer SRK-T formülü uygulanan grupta -0,19±0,37 D, SRK-2 formülü uygulanan grupta -0,12±0,77 D idi. Ortalama refraktif sapma SRK-T formülü kullanılan grupta 0,2±0,25 D iken, SRK-2 formülü kullanılan grupta 0,51±0,59 D idi ve refraktif sapma değerleri açısından iki grup arasında istatistiksel olarak anlamlı fark mevcuttu (p=0,001). Sonuç: Fakoemülsifikasyon cerrahisi öncesi SRK-T biyometrik formülü kullanılan grupta SRK-2 biyometrik formülü kullanılan gruba göre anlamlı olarak hedeflenen refraktif değere daha yakın sonuçlar elde edildi.
