| 发明名称 | Apparatus and method for generating cut surfaces in the cornea of an eye for correction of ametropia | ||
| 摘要 | An apparatus for generating cut surfaces in the cornea of an eye in order to correct ametropia is provided, said apparatus comprising a laser unit, which can focus pulsed laser radiation into the cornea and move it therein in order to generate cut surfaces, and a control unit, which controls the laser unit for generating cut surfaces such that a predetermined lenticle to be removed is separated from the surrounding corneal material in the cornea by at least one cut surface, and that at least two mutually spaced apart cut surfaces are formed as opening cuts, each extending from the lenticle to the anterior corneal surface, the position and shape of the opening cuts being selected such that the opening cuts contribute to the correction of the ametropia of the eye or do not counteract the correction of the ametropia of the eye. | ||

| 主权项 | 1. A method for generating cut surfaces in a cornea of an eye in order to correct ametropia using an apparatus, said apparatus comprising: a laser unit, which focuses pulsed laser radiation into the cornea and moves said focused radiation therein in order to generate cut surfaces within the cornea; and a control unit, which controls the laser unit for generating cut surfaces such that a predetermined lenticle to be removed is separated from the surrounding corneal material within the cornea by at least one cut surface, the method comprising: forming at least two mutually spaced apart cut surfaces as opening cuts that are structured such that the lenticle or a portion thereof can be removed therethrough and that are structured such that the opening cuts do not lead to a corneal flap that can be folded back, each opening cut extending from the lenticle within the cornea to an anterior corneal, and selecting a position and a shape of each opening cut such that the opening cuts contribute to the correction of the ametropia of the eye or do not counteract the correction of the ametropia of the eye being made. | ||
