Abstract：
A new therapeutic alternative has been developed in the past 6 years to treat severe keratoconus in young patients. Those patients had only corneal transplantation as an option, but now a variety of surgical alternatives in the form of allogeneic corneal inclusions have bloomed and are becoming more popular. Although Bowman layer transplantation is the most studied technique, recent studies have described different options with very promising preliminary results. Mostly all the techniques described improve corneal curvature, visual acuity, pachymetry, contact lens tolerance, and foremost, manage to avoid or postpone corneal transplantation. Very few complications have been described so far, which makes these techniques not only feasible but also safe. Herein, we focus on reviewing recently published studies describing these techniques and their first results.
摘要：
在过去的6年中，已经开发出一种新的治疗方法来治疗年轻患者的严重圆锥角膜。那些病人只有角膜移植作为一种选择,但是现在，以同种异体角膜内含物形式的各种手术替代方案已经蓬勃发展并变得越来越流行。尽管Bowman层移植是研究最多的技术，最近的研究描述了不同的选择，并取得了非常有希望的初步结果。大部分描述的所有技术都能改善角膜曲率，视敏度,测厚仪,隐形眼镜公差,最重要的是,设法避免或推迟角膜移植。到目前为止，很少有并发症被描述，这使得这些技术不仅可行而且安全。在这里，我们专注于回顾最近发表的描述这些技术的研究及其初步结果。
