Abstract
Purpose: To investigate the effects of cataract hardness on the parameters and complication rates of phacoemulsification surgery. Materials and Methods: A total of 154 eyes in 154 patients who underwent phacoemulsification surgery under local anesthesia were assigned to one of two groups for the purpose of the study: a soft cataract group (SC) in which cataracts had a hardness of +1 or +2 (51 patients), and a hard cataract group (HC) in which cataracts had a hardness of +3 or +4 (103 patients). The groups were compared in phacoemulsification parameters (phaco time, phaco power and effective phaco time) and complication rates. Results: Mean age in the SC group was 68.14±9.6 years, and in the HC group it was 71.03±8.9 years. Mean phaco-time in the SC group was 1.7±0.7 minutes, and in the HC group it was 3.0±1.1 minutes; while mean effective phaco-time in the SC group was 22.1±22.1 seconds, in the HC group it was found to be 46.2±24.0 seconds, and these differences were statistically significant (p<0.05). Mean phaco percentage in the SC group was 0.2±0.1, while in the HC group it was found to be 0.2±0.08, and the difference between the two groups was not statistically significant (p>0.05). In both groups a significant correlation was confirmed between cataract hardness and phaco-time (SC group r=0.317, p=0.023; HC group r=0.313, p=0.01). In terms of complications, in the SC group posterior capsule rupture (PCR) was seen in 4 patients (7.8%), and iris injury in 2 patients (3.9%). In the HC group, PCR was seen in 17 patients (16.5%), capsulorhexis discontinuity in 2 patients (1.9%) and iris injury in 1 patient (1%). In the HC group, moderate corneal edema was observed 16 patients (15.5%) and no corneal edema was observed in SC group. Surgical complications were significantly more frequent in the HC group (p<0.05). Conclusion: Increased cataract hardness caused both a lengthening of phaco-time and an increase in complication rate. So it will be more prudent to advise cataract patients to have early operation before cataract hardness reaches a challanging condition
Özet
Amaç: Fakoemülsifikasyon cerrahisinde katarakt sertliğinin fako parametreleri ve komplikasyon gelişme oranına etkilerinin incelenmesi. Gereç ve Yöntem: Lokal anestezi altında fakoemülsifikasyon cerrahisi geçirmiş, katarakt sertliği +1 ve +2 olan 51 hasta yumuşak katarakt (YK) grubu ve katarakt sertliği +3 ve +4 olan 103 hasta sert katarakt (SK) grubu olmak üzere toplam 154 hastanın 154 gözü çalışma kapsamına alındı. Hastalar fako parametreleri (fako zamanı, fako yüzdesi, efektif fako zamanı) ve komplikasyonlar açısından karşılaştırıldı. Bulgular: Ortalama yaş YK grubunda 68.14±9.6 yıl, SK grubunda 71.03±8.9 yıl idi. YK grubunda ortalama fako zamanı 1.7±0.7 dk., SK grubunda 3.0±1.1 dk.; efektif fako zamanı YK grubunda 22.1±22.1 sn. iken SK grubunda 46.2±24.0 sn. bulundu, her iki parametre için iki grup arasındaki fark istatistiksel olarak anlamlıydı (p 0.05). Her iki grupta katarakt sertliği ile fako zamanı arasında anlamlı korelasyon tespit edildi (YK grubu r=0.317, p=0.023; SK grubunda r=0.313, p=0.01). YK grubunda 4 (%7.8) hastada arka kapsül yırtığı (AKY), 2 (%3.9) hastada fakoya bağlı iris hasarı görüldü. SK grubunda ise 17 (%16.5) hastada AKY, 2 (%1.9) hastada düzensiz kapsüloreksis ve 1 (%1) hastada fakoya bağlı iris hasarı görüldü. SK grubunda 16 (%15.5) hastada orta derecede korneal ödem görülürken, YK grubunda korneal ödem izlenmedi. Cerrahi komplikasyonlar SK grubunda istatistiksel olarak anlamlı oranda fazla idi (p<0.05). Sonuç: Katarakt sertliğinin artması hem daha uzun fako zamanına hem de komplikasyon oranının artmasına sebep olmaktadır. Bu sebeple fako tekniği uygulanacak kataraktların çok sertleşmeden ameliyat edilmesi komplikasyonları azaltmak açısından uygun olacaktır.
