| 摘要 |
<p>The invention is a system and method for modifying the corneal curvature by irradiating the cornea to deliver thermal energy to the stroma (134). The system includes multiple irradiation ports for introducing electromagnetic radiation; positioning means (42) such as a hemispherical dome (12) with several tracks (14) for positioning the irradiation ports, respectively, at locations of a pre-selected geometric pattern relative to the pretreated cornea, the geometric pattern being selected to correspond to a desired modified shape of the cornea; transmission means (76) adapted to deliver controlled amounts of the radiation to introduce the radiation to treatment volumes (140) of the stroma in a cooperative manner to induce desired shrinkage of the collagenous stromal tissue and cause change in the corneal curvature.</p> |
