Abstract

Purpose: To evaluate the impact of femtosecond laser assisted cataract surgery on corneal endothelium and keratometric values.Materials and methods: Thirty-six eyes eyes of 24 patients who underwent femtosecond laser assisted cataract surgery in the between the period of June 2013 and June 2014 were reviewed. The visual acuity, anterior and posterior segment examination, intraocular pressure and keratometric values as an indicator of surgically induced astigmatism were measured. Corneal endothelial cell count was evaluated via specular microscope. The visual acuity, keratometric values and corneal endothelial cells were evaluated 3 months later. The results are statistically analyzed with the Chi-square test.Results: The difference between the pre- and postoperative astigmatism were not more than +/- 0.25 diopters . Mean endothelial cell loss was about 8% after surgery, but in no case the endothelial cell number reached the critical level which leads to corneal decompensation.Conclusion: The impact of femtosecond laser assisted cataract surgery on corneal endothelium and keratometric values is minimal. The impact of femtosecond laser assisted cataract surgery on corneal endothelium and astigmatism is very low and the visual results are predictable.

Özet

Amaç: Femtosaniye lazer yardımlı katarakt cerrahisinin kornea endoteli ve keratometrik değerlerine olan etkilerini değerlendirmek.Gereç ve yöntem: Haziran 2013- Haziran 2014 döneminde femtosaniye lazer yardımlı katarakt cerrahisi uygulanan 24 hastanın 36 gözü retrospektif olarak değerlendirildi. Hastaların görme keskinliği, cerrahi olarak oluşturulmuş olan astigmatizmayı değerlendirebilmek amacıyla keratometrik ölçümleri, detaylı ön ve arka segment muayeneleri, göz içi basınç ölçümlerinin yanı sıra, speküler mikroskopi ile kornea endotel hücre sayımı yapıldı. Ameliyattan 3 ay sonra keratometrik ölçümler ve kornea endotel hücre sayıları yeniden değerlendirildi. Sonuçlar istatistiksel olarak ki-kare testi ile analiz edildi.Bulgular: Preoperatif ve postoperatif keratometrik değerler arasında ortalama +/- 0.25 diyoptrilik bir farklılık mevcuttu. Kornea endotel hücrelerindeki kayıp ise % 8 civarında olup hiçbir hastada dekompanzasyona neden olacak kritik seviyelere ulaşmadı.Sonuç: Femtosaniye lazer yardımlı katarakt cerrahisinin kornea endoteli ve keratometrik değerlerine olan etkilerinin çok hafi f olduğu ve görsel sonuçlarının daha öngörülebilir olduğu sonucuna varıldı.
