    • An accommodative intraocular lens is provided to replace a natural lens. The intraocular lens structure includes an optical portion and a haptic portion. The optical portion includes a replacement lens while the haptic portion includes the structure that holds the lens in position while keeping the anterior capsular sac taunt and annular in shape. The haptic in the present invention stabilizes the annular structure of the peripheral zone at the capsular sac's largest diameter and also stabilizes the conical structure of the capsular sac as well. The haptic structure includes a helical coil of increasing radius from the lens to the terminating annular ring that thus forms a conical coil spring. Compression and relaxation of the coiled (spring) haptics between the anterior and posterior capsule, during tightening and relaxation of lens zonule and ciliary body, move the lens to anteriorly and posteriorly and induces accommodation.
    • 提供调节型眼内透镜来代替天然镜片。 眼内透镜结构包括光学部分和触觉部分。 光学部分包括替换透镜,而触觉部分包括将透镜保持在适当位置的结构,同时保持前囊泡囊状和环形形状。 本发明中的触觉装置使囊周围区域的环状结构稳定在囊状囊的最大直径处,并且还稳定囊囊的锥形结构。 触觉结构包括从透镜到端接环形环的增加的半径的螺旋线圈,从而形成锥形螺旋弹簧。 压缩和放松前后胶囊之间的螺旋(弹簧)触觉,在镜片区和睫状体的收紧和松弛过程中,将镜片向前和向后移动并诱导调节。
