Abstract

Aim: To evaluate the efficacy of postoperative corneal haze prophylaxis with topical application of mitomycin C (MMC) in myopic photorefractive keratectomy (PRK). Material and Method: Medical records of patiens who underwent PRK (sixty-one eyes without MMC application and 55 eyes with 0.02% MMC application) were analyzed retrospectively. After 12 month's follow-up period, two groups were compared with regard to postoperatif UCVA, postoperative BCVA, postoperatif spherical refractive error, postoperatif cylindirical refractive error, safety ratio, efficacy ratio (EFFR) and postoperative haze scores. Results: Preoperatively, there were no difference between two groups with regard to age, spherical error, cylindirical error, spherical equivalent (SE) and best corrected visual acuity. Preoperatif mean spherical equivalent (SE) was -5.88±0.40 D in the MMC applied eyes and -6.42±0.41 D in the control eyes (p>0.05). At 12 months, mean SE was 0.02±0.19 D in the Mitomisin C eyes and -0.20±0.18 D in the control eyes (p>0.05). There were no difference between two groups with regard to postoperative uncorrected visual acuity, effectivity and safety. Mean haze was 0.36±0.07 in the MMC applied group and was 0.62± 0.06 in the control group. The difference between groups was statistically significant (p=0.008). Conclusions: Corneal haze formation was less in cases who underwent PRK with intraoperative MMC than cases who underwent PRK without MMC.

Özet

Amaç: Miyopik fotorefraktif keratotomi (PRK) uygulamalarında Mitomisin C uygulamasının (MMC), postoperatif haze gelişimi profilaksisi üzerine etkinliğini incelemek. Gereç ve Yöntem: PRK operasyonu geçirmiş, intraoperatif % 0,02 MMC uygulanan 35 hastanın 55 gözü ve intraoperatif MMC uygulanmayan 40 hastanın 61 gözüne ait tıbbi kayıtlar retrospektif olarak incelendi. Hastaların 12 aylık takiplerinin sonunda iki grup, postoperatif düzeltilmemiş görme keskinliği, postoperatif düzeltilmiş en iyi görme keskinliği, postoperatif sferik kırma kusuru, postoperatif astigmatizma değeri, postoperatif sferik eşdeğer (SE), efektivite, güvenirlik ve haze skorları açısından karşılaştırıldı. Bulgular: Gruplar arasında yaş, preoperatif sferik kırma kusuru, preoperatif silindirik kırma kusuru, preoperatif SE ve preoperatif en iyi düzeltilmiş görme keskinliği açısından fark yoktu. Preoperatif ortalama SE, MMC uygulanan gözlerde -5,88±0,40 D, kontrol grubunda -6,42±0,41 D idi (p>0,05). Onikinci aydaki ortalama SE, MMC’li grupta 0,02±0,19, kontrol grubunda -0,20±0,18 (p>0.05) olarak hesaplandı. Postoperatif en iyi düzeltilmemiş görme keskinliği, efektivite ve güvenirlik oranları açısından iki grup arasında anlamlı bir fark bulunmadı. MMC grubunda ortalama haze skoru 0,36±0,07, kontrol grubunda 0,62±0,06 olarak bulundu ve iki grup arasındaki fark istatiksel olarak anlamlı idi (p=0,008). Sonuç : Miyopik PRK uygulamalarında topikal MMC uygulanan gözlerde, uygulanmayan gözlere oranla daha az haze gelişmektedir.
