Abstract

Pur po se: To evaluate the effects of silicone hydrogel contact lenses (SHCL) on central corneal thickness (CCT), corneal endothelial cell morphology, and tear functions. Ma te ri al and Met hod: Fifty-five eyes of 28 SHCL wearers (Group 1) and 52 eyes of 26 healthy subjects (Group 2) were included in this study’. According to their contact lens wearing time, the contact lens wearing subjects were divided into 2 groups: Group 1a - wearing time less than 1 year and Group 1b - wearing time more than 1 year. CCT, epithelial thickness, corneal endothelial cell morphology, ocular surface disease index score (OSDI), and tear break-up time (TBUT) were evaluated. Re sults: In Group 1 and Group 2, the mean CCT was 561.85±39.98 μm and 537.25±27.12 μm, respectively (p: 0.001).The epithelial thickness was 50.38±5.41 μm and 55.64±5.32 μm, respectively (p: 0.001). In Group 1a and Group1 b, the mean CCT was 573.39±33.86 μm and 546.96±42.98 μm (p: 0.014) and the epithelial thickness was 49.51±4.78 μm and 51.50±6.04 μm (p>0.05), respectively. In Group 1, the percentage of endothelial cells larger than 700μ was low, while the percentage of endothelial cells between 200 and 400μ was high (p

Özet

Amaç: Silikon hidrojel kontakt lenslerin (SHKL); santral kornea kalınlığına (SKK), kornea endotel hücre morfolojisine ve gözyaşı fonksiyonlarına etkilerinin değerlendirilmesi. Ge reç ve Yön tem: Silikon hidrojel kontakt lens kullanan 28 olgunun 55 gözü ile (Grup 1), kontakt lens kullanmayan 26 sağlıklı bireylerin 52 gözü (Grup 2) çalışma kapsamına alındı. Lens kullanan olgular kontakt lens kullanım ’sürelerine göre Grup 1a: 1 yıldan az, Grup 1b: 1 yıldan fazla olmak üzere ikiye ayrıldı. Tüm olgularda SKK ve kornea epitel kalınlığı, kornea endotel hücre morfolojisi, oküler yüzey hastalık indeks skoru (OSDİ) ve gözyaşı kırılma zamanı (GKZ) değerlendirildi. Sonuçlar: Grup 1 ile Grup 2’de ortalama SKK sırasıyla 561,85±39,98 μm; 537,25±27,12 μm(p: 0,001), epitel kalınlığı 50,38±5,41μm, 55,64±5,32 μm bulundu (p: 0,001). Grup 1a ve 1b’de ortalama SKK sırasıyla 573,39±33,86 μm; 546,96±42,98 μm (p: 0,014), epitel kalınlığı 49,51±4,78 μm, 51,50±6,04 μm (p>0,05) idi. Grup 2’ye göre Grup 1’de 700μ’dan büyük endotel hücre yüzdesi daha az, 200-400μ arasındaki endotel hücre yüzdesi fazlaydı ( p
