Abstract

Purpose: To evaluate the central and peripheral corneal volume changes after uneventful phacoemulsification. Materials and Methods: Forty-two eyes of 34 (26 male and 8 female) patients who, underwent uneventful phacoemulsification, were examinedenrolled in this study. Corneal volumes of 3 mm, 5 mm, and 7 mm corneal volumes were measured using Scheimflug imaging (Pentacam, Oculus, Inc.) preoperatively and postoperatively at after 1st, 3rd, and 6th months. The paired t-test was used to compare preoperative and 1, 3, and 6 months’ postoperative corneal volume measurements. Results: Mean corneal volumes in 3 mm, preoperatively, and postoperatively at 1st, 3rd, and 6th months postoperatively were 3.84±0.23 mm3, 3.85±0.26 mm3, 3.83±0.25 mm3, and 3.89±0.25 mm3, respectively. Mean corneal volumes measurements in 5 mm preoperatively and postoperatively at 1st, 3rd, and 6th months postoperatively were 11.160± 0.67 mm3, 11.255±0.75 mm3, 11.155±0.75 mm3, and 11.286±0.73 mm3, respectively. Mean corneal volume measurements in 7 mm, preoperatively and postoperatively at 1st, 3rd, and 6th months postoperatively were 23.66±1.52 mm3, 23.89±1.64 mm3, 23.74±1.67 mm3, and 23.79±1.58 mm3, respectively. The mean 3 mm, 5 mm, and 7 mm central corneal volumes measurements did not reveal show any significant change preoperatively and or at postoperative 1, 3, and 6 months (p>0.05). Conclusion: A positive relationship between endothelial damage and corneal volume was known. So Therefore, corneal volume measurements in 3, 5, and 7 mm taken obtained with Pentacam can be useful to show corneal endothelial changes after phacoemulsification surgery.

Özet

Amaç: Sorunsuz fakoemülsifikasyon ameliyatı sonrası, merkezi ve periferal korneal hacim değişimlerini değerlendirmek. Gereç ve Yöntem: Çalışmaya sorunsuz fakoemülsifikasyon cerrahisi uygulanan 34 hastanın 42 gözü dahil edildi. Hastaların, merkezi 3, 5 ve 7 mm’deki kornea hacimleri, ameliyat öncesi ve ameliyat sonrası 1., 3. ve 6. aylarda Pentacam ön segment analiz cihazı ile değerlendirildi. Ameliyat öncesi ve ameliyat sonrası 1., 3., ve 6. aylar arasındaki kornea hacim değişiklerini karşılaştırmak için eşleştirilmiş t testi kullanıldı. Bulgular: Hastaların 3 mm’deki ortalama kornea hacimleri ameliyat öncesi, ameliyat sonrası 1., 3. ve 6. aylardaki değerleri sırası ile 3.84±0.23 mm3, 3.85±0.26 mm3, 3.83±0.25 mm3 ve 3.89±0.25 mm3 bulundu. 5 mm’deki kornea hacim değerleri ortalaması, ameliyat öncesi ve ameliyat sonrası 1., 3. ve 6. aylarda sırası ile 11.16± 0.67 mm3, 11.26±0.75 mm3, 11.16±0.75 mm3 ve 11.29±0.73 mm3 bulundu. 7 mm’deki kornea hacim değerlerinin ortalaması, ameliyat öncesi, ameliyat sonrası 1., 3., ve 6. aylarda sırası ile 23.66±1.52 mm3, 23.89±1.64 mm3, 23.74±1.67 mm3 ve 23.79±1.58 mm3 olarak bulundu. Ameliyat öncesi ve ameliyat sonrası 1., 3. ve 6. aylarda 3 mm, 5 mm ve 7 mm’deki kornea hacim değişimleri istatistiksel açıdan anlamlı bulunmadı (p>0.05). Sonuç: Endotel hasarı ile korneal hacim arasında pozitif bir bağlantının olduğu bilinmektedir. Bu bilgi ışığında Pentacam-Scheimflug görüntüleme sistemi ile korneanın merkezi 3, 5, ve 7 mm alanlarından alınan hacim ölçümleri, kornea endotelindeki değişimleri göstermesi açısından faydalı olabilir
