Abstract

Purpose: To Evaluation evaluation of the anterior chamber depth and iridocorneal angle changes by the anterior segment optical coherence tomography (Visante OCT) after standard phacoemulsification and implantation of an intraocular lens. Materials and Methods: Thirty-five eyes of 45 patients with aof mean age of 70±10.17 years (22 female, 13 male) were included in the study. All patients underwent uneventful phacoemulsification and intraocular lens (IOL) implantation in the bag with temporal clear corneal incision. Following a detailed ophthalmological examination, anterior segment optical coherence tomography was performed on preoperatively and afteron 1st day, 1 st week, and 1 st month postoperatively. Preoperative endothelium-lens distance, and nasal and temporal anterior chamber angles, and postoperative endothelium-IOL distance, and nasal and temporal anterior chamber angles were measured. Statistical analysisThe data were done analyzed bywith paired t-test, Wilcoxon rank test, and ANOVA test. Results: Mean preoperative endothelium-lens distance was 2.54±0.46 millimeter (mm preoperatively) and, mean endothelium-IOL distance was 3.99±0.35 mm on after 1st 1 day, 3.97±0.28 mm on after 1st 1 week, and 3.91±0.25 mm on after 1st 1 month postoperatively. The mean preoperative nasal angle was 25.15±6.79 degrees (º) and, mean postoperative nasal angle was 39.39±5.38º on after 1st 1 day, 40.60±5.95º after 1 week after operation, and 41.23±4.62º after one 1 month after operation. Mean preoperative temporal angle was 24.17±7.39º and, mean postoperative temporal angle was 38.21±4.78º on after 1st 1 day, 40.57±6.32º after 1 week after operation, and 41.48±5.21º after one 1 month after operation. At each controlexamination, the endothelium-IOL distance, and nasal and temporal angle values were significantly found increased when compared tohigher than preoperative values and these were statistically significant (p<0.001). Conclusion: The changes in the anterior chamber depth and iridocorneal angle parameters can be evaluated quantitatively by Visante OCT after phacoemulsification and IOL implantation surgery.

Özet

Amaç: Standart fakoemülsifikasyon ve göz içi lensi (GİL) yerleştirilmesinden sonra meydana gelen ön kamara derinliği ve iridokorneal açı değişikliklerinin ön segment optik koherens tomografisi (Visante OCT) ile değerlendirilmesi. Gereç ve Yöntem: Yaş ortalaması 70±10.17 yıl olan 13’ü erkek, 22’si kadın 35 hastanın 45 gözü çalışmaya dahil edildi. Tüm hastalara temporal kornea kesisi ile komplikasyonsuz fakoemulsifikasyon ve kapsül içi GİL yerleştirilmesi operasyonu uygulandı. Hastaların ameliyat öncesi, 1. gün, 1. hafta ve 1. ay kontrollerinde detaylı oftalmolojik muayeneyi takiben ön segment optik koherens tomografisi ölçümleri alındı. Visante OCT (Carl Zeiss Meditec) ile ön kamarada ameliyat öncesinde endotel-lens mesafesi, nazal ve temporal ön kamara açıları, ameliyat sonrasında ise endotel-GİL mesafesi, nazal ve temporal ön kamara açıları ölçüldü. İstatistiksel analiz paired t-test, Wilcoxon rank testi ve ANOVA testi kullanılarak yapıldı. Bulgular: Ameliyat öncesinde endotel-lens mesafesi ortalama 2.54±0.46 milimetre (mm), ameliyat sonrası 1. günde endotel-GİL mesafesi ortalama 3.99±0.35mm, 1. haftada 3.97±0.28mm ve 1. ayda 3.91±0.25mm bulundu. Nazal açı ameliyat öncesi ortalama 25.15±6.79 derece (º), ameliyat sonrası 1. günde 39.39±5.38º, 1. haftada 40.60±5.95º ve 1. ayda 41.23±4.62º; temporal açı ameliyat öncesi 24.17±7.39º, ameliyat sonrası 1.günde 38.21±4.78º, 1. haftada 40.57±6.32º ve 1. ayda 41.48±5.21º olarak bulundu. Tüm kontrollerde endotel-GİL mesafesi, nazal ve temporal açı değerleri ameliyat öncesi değerlere göre istatistiksel olarak anlamlı derecede artmış bulundu (p<0.001). Sonuç: Fakoemülsifikasyon ve GİL yerleştirilmesi ameliyatından sonra ön kamara derinliği ve iridokorneal açı parametrelerindeki değişiklikler Visante OCT ile kantitaif olarak değerlendirilebilmektedir.
