Keratorefractive Effect of High Intensity Focused Ultrasound Keratoplasty on Rabbit Eyes

Keratorefractive Effect of High Intensity Focused Ultrasound Keratoplasty on Rabbit Eyes

Purpose. To evaluate high intensity focused ultrasound (HIFU) as an innovation and noninvasive technique to correct presbyopia by altering corneal curvature in the rabbit eye. Methods. Eighteen enucleated rabbit eyes were treated with a prototype HIFU keratoplasty. According to the therapy power, these eyes were divided three groups: group 1 (1 W), group 2 (2 W), and group 3 (3 W). The change i...

The Effect of High Intensity Focused Ultrasound Keratoplasty on Rabbit Anterior Segment

Purpose. To evaluate the safety of high-intensity focused ultrasound keratoplasty as a treatment for presbyopia by examining its effect on the rabbit anterior segment. Methods. The right corneas of 36 New Zealand rabbits were treated with HIFU keratoplasty. The animals were sacrificed at 1, 7, 15, 30, 60, and 90 days after operation. Collagen type I, MMP-2, and MMP-9 were evaluated using immuno...

High-Intensity Focused Ultrasound –

High intensity focused ultrasound (HIFU).

INTRODUCTION Curative treatments for localized prostate cancer, from least invasive to most invasive, include brachytherapy, cryosurgery, three-dimensional conformal radiation therapy, external beam radiation therapy, and radical prostatectomy. A patient with localized, low risk or intermediate risk prostate cancer who is diagnosed at an early age and receives one of these treatments has only a...

A microsurgical bifurcation rabbit model to investigate the effect of high-intensity focused ultrasound on aneurysms: a technical note

BACKGROUND Recent clinical studies confirmed the high potential of MR-guided focused ultrasound (MRgFUS) in the field of functional neurosurgery. While its ability for precise thermo-ablation within soft tissue is widely recognized, the impact of high-intensity focused ultrasound (HIFU) on larger vessels is less explored. We used a bifurcation aneurysm model in rabbits to investigate the possib...
