Abstract

Aim: Investigate corneal changes in patients who use contact lenses.
Materials and Methods: 18 patients included in this study. Central corneal thickness and keratometry measured by topography, corneal endothelial values obtained using specular microscope and Schirmer results were recorded.
Results: The mean age was 22.77±4.00. 15 patients were female, 3 male. K1, K2, CCT and endothelial cell count levels showed decreases after lens use (p<0.05). An increase was observed in posterior K1.
Conclusion: Despite their high oxygen permeability, silicone hydrogel lenses still affect the physiology and architecture of the cornea.

Yumuşak kontakt lens kullanıcılarında korneal değişikliklerin incelenmesi

Abstract

Amaç: Kontakt lens kullanan hastalardaki korneal değişimlerin incelenmesi.
Gereç ve Yöntem: Kontakt lens kullanmak için başvuran 18 olgunun, topografi cihazı ile ölçülen merkezi korneal kalınlık (MKK) ve keratometri değerleri (K1, K2), speküler mikroskop cihazı kullanılarak elde edilen kornea endotel değerleri ve schirmer testi sonuçları kaydedildi.
Bulgular: Çalışmaya 18 hastanın 36 gözü dâhil edildi. Olguların yaş ortalaması 22,77±4,00, 15’i kadın, 3’ü erkekti. K1, K2, MKK ve endotel sayısı değerlerinde lens kullanımı sonrası anlamlı bir azalma olduğu görüldü. (p<0,05) Posterior K1 değerinde lens kullanımından sonra anlamlı bir artış olduğu görüldü.
Sonuç: Silikon hidrojel lensler yüksek oksijen geçirgenliğine rağmen korneanın fizyolojisi ve mimarisini hala etkileyebilmektedir.
