Abstract

Purpose : To investigate the surgically induced astigmatism after 3.2 mm temporal or superior clear corneal incisions in phacoemulsification+ foldable inraoculer lens (IOL) implantation. Methods : 31 eyes of 25 patients with temporal clear corneal incision and 27 eyes of 25 patients with superior clear corneal incision were included in the study. Foldable acrylic ıntraocular lens (Acrysof®. Alcon) was implanted through 3.2 mm incision in all eyes. Surgically induced astigmatism was evaluated with vector analysis at 1. week. 1. month and 3. month. Mann-Whitney U test was used for statistical analysis. Results : Mean surgically induced astigmatism was 0.48±0.47 D in temporal group and 0.85±0.76 D in superior group at 1.week (p>0.05). 0.47±0.42 D and 0.96±0.80 D at 1.month (p=0.02). 0.48±0.49 D and 0.92±0.75 D at 3.month (p=0.02). According to vector analysis of Cravy method. mean surgically induced astigmatism shifted 0.24±0.60 D. 0.02±0.53 D.0.05±0.61 D with-the-rule in temporal group. -0.69±0.86 D.-0.88±0.92 D.-0.80±0.95 D against-the-rule in superior group at 1. week. 1.month and 3.month (p=0.0001. p=0.0004. p=0.0009) respectively. Conclusion : Surgically induced astigmatism was different at two groups in the aspect of astigmatism type and amount. Lower and with-the-rule astigmatism was observed in temporal clear corneal incision. Against-the-rule astigmatism shift was noted in superior clear corneal incision.

Özet

Amaç: Üstten veya temporalden uygulanan 3.2 mm saydam kornea kesiyi takiben fakoemülsifikasyon+katlanabilir intraoküler lens yerleştirilmesi sonucunda oluşan cerrahiye bağlı astigmatik değişimin incelenmesi. Gereç-Yöntem: Temporal saydam kornea keşi uygulanan 25 hastanın 31 gözü ve üstten saydam keşi uygulanan 25 hastanın 27 gözü çalışma kapsamına alındı. Tüm gözlere 3.2mm'lik keşiden katlanabilir akrilik göz içi lensi (AcrySof®, Alcon) yerleştirildi, l.hafta, l.ay ve 3.ayda oluşan cerrahiye bağlı astigmatizma vektör analizi ile incelendi. Veriler Mann-Whitney U istatistik yöntemi ile karşılaştırıldı. Bulgular: 1.haftada oluşan cerrahiye bağlı astigmatizma temporal saydam korneal kesili grupta ortalama 0.48±0.47D ve üst saydam korneal kesili grupta 0.85±0.76D idi (p>0.05). Bu değerler l.ayda temporal kesili grup için 0.47±0.42D ve üstten kesili grup için 0.96±0.80D (p=0.02), 3.ayda temporal kesili grup için 0.48±0.49D ve üstten kesili grup için 0.92±0.75D (p=0.02) oldu. Cravy'nin eksene dayalı tetkikine göre temporal kesili grupta l.hafta,l.ay ve 3. ayda sırası ile 0.24±0.60D,0.02±0.53D ve 0.05±0.61D'lik kurala uygun astigmatizmaya, üstten kesili grupta ise l.hafta, l.ay ve 3.ayda sırasıyla -0.69±0.86D,-0.88±0.92D ve -0.80±0.95D'lik kurala aykırı astigmatizmaya kayış tespit edildi (p=0.0001, p=0.0004, p=0.0009). Sonuç: Cerrahiye bağlı astigmatizmamn miktarı ve yönü açısından her iki grubun farklı olduğu gözlendi. Temporal kesilerde oluşan astigmatik değişikliğin hem daha az, hem de kurala uygun olduğu, üstten yapılan saydam kesilerde ise kurala aykırı astigmatizmaya eğilim olduğu görüldü.
