Comparison of Burst, Pulse, and Linear Modes Used in Phacoemulsification Surgery

Abstract

Phacoemulsification power should be kept at minimum in order to induce minimal trauma and to achieve early rehabilitation.

Microincision versus small-incision coaxial cataract surgery using different power modes for hard nuclear cataract

“…€ Ozkurt et al 17 report that the CCT was significantly higher in a pulse-mode group than in a burstmode group at 1 day and 1 week, whereas there were no significant differences between the pulse and continuous modes and between the burst and continuous modes. € Ozkurt et al 17 report that the increased CCT in pulse mode was associated with the higher US power.…”

Torsional and burst mode phacoemulsification for patients with hard nuclear cataract

“…[21] In addition, burst ultrasound mode can reduce the overall ultrasound energy, as evidenced by less mean CDE, and the effective UST in the torsional and burst mode compared with the conventional mode. As high ultrasound energy is associated with increased damage to corneal endothelial cells, [4] the lower energy used in torsional and burst mode may contribute to less corneal endothelial cell injury. Our findings are consistent with the previous reports that the torsional burst phacoemulsification mode was associated with greater safety and less damage to the corneal endothelial cells compared with the conventional phacoemulsification mode.…”

“…Damage of the corneal endothelial cells during cataract surgery positively correlates with the power and time of ultrasound. [4] Burst ultrasound mode can reduce the overall ultrasound energy by reducing the mean CDE and the effective UST. Therefore, the combined torsional and burst mode has better efficiency than the conventional mode, and damage to the surrounding ocular tissue is less.…”

Estudio clínico comparativo de la refracción obtenida tras facoemulsificación con implante de lente intraocular al realizar la biometría con el Iolmaster y Otiscan-1000 en función de la longitud axial

“…Hemos encontrado una correlación directa entre la cantidad de edema corneal y estos dos parámetros, como ya se había observado previamente 108 . Sin embargo, no existe una correlación entre estos dos parámetros y la refracción final, tanto esférica como cilíndrica ni tampoco con la estabilización refractiva o paquimétrica.…”
