Intraocular lens development is driven by higher patient expectations for ideal visual outcomes. The recently US Food and Drug Administration-approved Softec HD(™) lens is an aspheric, hydrophilic acrylic intraocular lens (IOL). The hydrophilic design of the lens is optimized to address dysphotopsia while maintaining biocompatibility, optical clarity, resistance to damage, and resistance to biocontamination. Aspheric lenses decrease postoperative spherical aberration. The addition of the Softec lens provides clinicians with another option for IOL placement; however, randomized comparative studies of this lens to others already on the market remain to be completed.
人工晶状体的发展是由患者对理想视觉效果的更高期望所推动的。最近美国食品药品监督管理局批准的Softec HD(™)晶状体是一种非球面、亲水性丙烯酸人工晶状体(IOL)。该晶状体的亲水性设计经过优化,以解决眩光问题,同时保持生物相容性、光学清晰度、抗损伤性和抗生物污染性。非球面晶状体可减少术后球差。Softec晶状体的加入为临床医生提供了另一种人工晶状体植入选择;然而,该晶状体与市场上其他现有晶状体的随机对照研究仍有待完成。
