The effect of anterior chamber depth on endothelial cell count and postoperative corneal edema in phacoemulsification surgery

Öz

Objectives: To investigate the effect of anterior chamber depth on corneal endothelial cell loss and development of postoperative corneal edema in patients undergoing pha­coemulsification surgery. Materials and methods: The effect of preoperative an­terior chamber depth was evaluated by ultrasound bi­ometry of 35 eyes with senile cataract and treated with phacoemulsification on intraoperative endothelial cell loss and at postoperative central corneal thicknesses by specular microscopy. Results: The mean age was 64.8 ± 10.7 years (range 42-84). Preoperative anterior chamber depth, cell density and central corneal thickness were 3.37 ± 0.51 mm (1.61-4.33 mm), 2345 ± 341 cell/mm² (1600-2915 cell/mm²) and 536 ± 32 μ (457-588 μ) respectively. Postoperative endothelial cell densities were detected 1876 ± 443 cell/mm², 1882 ± 457 cell/mm² and 1920 ± 456 cell/mm² at first week, first month and at third month respectively. Compared to preoperative values, decreases of endothe­lial cell densities at postoperative first week, first month and third month were found to be significant (p

Fakoemülsifikasyon cerrahisinde ön kamara derinliğinin endotel hücre sayısı ve postoperatif korneal ödem üzerine etkisi

Öz

Amaç: Fakoemülsifikasyon cerrahisi yapılan olgularda, ön kamara derinliğinin korneal endotel hücre kaybına ve postoperatif korneal ödem gelişimine etkisinin incelenme­si. Gereç ve yöntem: Senil katarakt tanısı alıp fakoemülsifi­kasyon cerrahisi uygulanmış 35 vakanın ultrasonik biyo­metri ile ölçülen preoperatif ön kamara derinliğinin endo­tel hücre kaybı ve postoperatif santral kornea kalınlığına etkisi, speküler mikroskopi verileri kullanılarak incelendi. Bulgular: Olguların yaş ortalaması 64.8 ± 10.7 yıl (42 - 84 yaş) idi. Preoperatif ön kamara derinliği 3.37 ± 0.51 mm (1.61-4.33 mm), hücre yoğunluğu 2345 ± 341 hücre/mm² (1600-2915 hücre/mm²) santral kornea kalınlığı (SKK) 535.9 ± 32.3 μ (457-588 μ) idi. Postoperatif endotel hüc­re yoğunluğu 1. haftada 1876 ± 443 hücre/mm², 1. ayda 1882 ± 457 hücre/mm², 3. ayda 1920 ± 456 hücre/mm² olarak saptandı. Preoperatif değer ile kıyaslandığında; 1. hafta, 1. ay ve 3. aydaki hücre yoğunluğu azalmalarının anlamlı olduğu bulundu (p
