    • Instruments and methods are provided which permit a surgeon to implant multiple radial inserts within a patient's cornea through one or more incisions made into the cornea. Instruments provided by the invention include a corneal marker, a radial pocket-forming instrument, and a positioning instrument. In one method provided by the invention, the surgeon uses the corneal marker to mark the patient's cornea with an incision mark, radial pocket marks, and circumferential channels marks simultaneously. The surgeon forms clockwise and counter-clockwise intrastromal circumferential channels through a single incision into the cornea, and then the surgeon inserts the radial pocket-forming instrument through the incision and into one of the circumferential channels to form radial pockets beneath the radial pocket marks. The surgeon inserts radial intrastromal inserts through the incision and into the circumferential channels and positions them within the radial pockets using the positioning instrument.
    • 提供的仪器和方法允许外科医生通过制成角膜的一个或多个切口在患者的角膜内植入多个径向插入物。 本发明提供的仪器包括角膜标记物,径向口袋形成仪器和定位仪器。 在本发明提供的一种方法中,外科医生使用角膜标记物同时用切口标记,径向袋痕迹和圆周通道标记来标记患者的角膜。 外科医生通过单个切口进入角膜形成顺时针和逆时针的基底内圆周通道,然后外科医生通过切口将径向口袋形成器械插入到其中一个周向通道中,以在径向穴位下方形成径向穴。 外科医生通过切口插入径向的基质内插入物并进入圆周通道,并使用定位仪将它们定位在径向穴内。
