AI Summary & Key Takeaways
AI InsightConclusion: Lowest dissipated energy with highest efficiency was gained in the group that is longitudinal energy was descending and torsional energy was in ascending order, so torsional method is more effective and more preferable method in phacoemulsification surgery.
📌 3 Key Takeaways
Abstract
Purpose: Comparison of longitudinal and torsional energies regarding on-time parameters. Materials and Methods: This prospective study comprised 75 eyes of 75 patients, that is grouped into three. In the first group, longitudinal and torsional on-time was fixed, in the second group longituinal and torsional on-time was in ascending order, and in the third group, longitudinal on-time was descending, while torsional on-time was in ascending order. Cumulative dissipated energy (CDE), phaco and torsional time, used at foot position 3, aspiration time were accepted as measures of efficiency and compared. Results: As for the comparison of cumulative dissipated energy, statistically lowest energy was measured in the third group. For the comparison of phaco time, torsional time and aspiration time again lowest measures were gained in the third group. Conclusion: Lowest dissipated energy with highest efficiency was gained in the group that is longitudinal energy was descending and torsional energy was in ascending order, so torsional method is more effective and more preferable method in phacoemulsification surgery.
Özet
Amaç: Fakoemülsifikasyonda longitudinal ve torsional enerjilerin on-zamanı parametrelerine göre karşılaştırılması. Gereç ve Yöntem: Bu prospektif çalışmaya 75 hastanın 75 gözü dahil edildi. Hastalar 3 gruba ayrıldı, birinci gruptaki 25 hastada longitudinal ve torsional on-zamanı sabit tutuldu, ikinci gruptaki 25 hastada longitudinal ve torsional on-zamanı artan oranda, üçüncü gruptaki 25 hastaya ise longitudinal on-time azalan, torsional on-zamanı artan oranda ayarlandı. Kümülatif yayılan enerji (KYE), ayak pedalı 3. pozisyondayken fako ve torsional zaman, aspirasyon zamanı verimlilik açısından karşılaştırıldı. Bulgular: Kümülatif yayılan enerji açısından yapılan karşılaştırmada, istatistiksel anlamlı olarak en düşük enerji 3. gruptaki hastalarda bulundu. Fako zamanı, torsional zaman ve aspirasyon zamanı açısından en kısa süre gene 3. grupta elde edildi. Sonuçlar: Fakoemülsifikasyonla en az enerji yayılımı ve en yüksek verimlilik longitudinal on zamanı azalan ve torsional on zamanı artan oranda ayarlanan grupta elde edilmiştir. Bu nedenle torsional metot fako cerrahisinde çok daha etkin ve tercih edilmesi gereken bir yöntemdir.
