Comparison of Two Different Ultrasound Methods of Phacoemulsification

A novel method to compare phacoemulsification parameters in vivo: two halves of one nucleus

“…Comparison of US modalities is frequently debated [1][2][3][4][5] while objective comparative studies are lacking as it is virtually impossible to select comparable groups [6]. The difficulties in the correct preoperative evaluation of the nuclei hardness and variability in lens sizes make it hard to objectively assess the advantages of phaco parameters in the traditionally designed comparative studies, which may look like an Bapples to oranges^rather than Bapples to apples^comparison of technologies [6].…”

Can we improve the efficacy of modern cataract surgery by using different tip designs? A comparison of balanced and tapered tip in femtosecond laser‐assisted cataract surgery and manual phacoemulsification

“…The efficiency of torsional phacoemulsification is influenced by the tip's anatomy . On the other hand, longitudinal phacoemulsification works by forward and backward movement of the phaco tip using the jackhammer effect . The drawback of torsional phacoemulsification is clogging, which can be prevented by a short burst of longitudinal phaco to avoid this complication …”

“…12 On the other hand, longitudinal phacoemulsification works by forward and backward movement of the phaco tip using the jackhammer effect. 3,11,13 The drawback of torsional phacoemulsification is clogging, which can be prevented by a short burst of longitudinal phaco to avoid this complication. 3,4,11,13 We designed a study to assess the clinical effects of two phaco tips, Intrepid balanced tip (BT) and Kelman tapered tip (TT), by comparing the intraoperative and short-term outcome of upgraded torsional microcoaxial phacoemulsification surgery and femtosecond laser-assisted cataract surgery (FLACS).…”

Efecto de la dexametasona tópica preoperatoria en el endotelio corneal y en biomarcadores inflamatorios de cámara anterior en la cirugía de la catarata del paciente diabético

“…Esto es debido a que la repulsión apenas existe, a diferencia de lo que ocurre con la energía longitudinal. La fractura de la catarata ocurre por cizallamiento y no solamente por el efecto de martillo neumático convencional 3,5,[8][9][10]111,113,114 .…”

“…La reducción de potencia de los US y la mejora de su eficiencia son los principales objetivos para reducir este efecto. A pesar de todos los avances, la cirugía moderna de la catarata condiciona una pérdida de un 5-15% de las CEC, frente a las técnicas más antiguas que condicionaban una mayor pérdida endotelial [3][4][5][6][7][8][9][10][11][113][114][115] .…”
