To review the corneal biomechanic concepts and to analyse, clarify and understand their relevance in refractive surgery.
A literature review has been done using different databases.
Corneal biomechanic concepts are not new and are applied implicitly in numerous surgical procedures. Their origin is related to tonometry studies, but they gained in popularity when they were linked to the treatment of keratoconus, a pathology in which the mechanical properties of the cornea are altered. Factors determining corneal stability were thus defined. Corneal biomechanics have also been used following refractive surgery to study post-operative keratectasia and to improve ablation patterns, which ignores the corneal response. The new ablation systems need to include the biomechanical factors, which motivate research conducted in physical-mathematical models and in corneal wound healing, improving our knowledge about the corneal biomechanical response.
The corneal biomechanic concepts have gained in popularity with the advent of refractive surgery, although they did exist previously. Their relevance is linked to improvements in the ablation systems used in an attempt to obtain more accurate and reliable results.
回顾角膜生物力学概念,并分析、阐明和理解其在屈光手术中的相关性。
利用不同数据库进行了文献综述。
角膜生物力学概念并不新颖,且在众多外科手术中被隐性应用。其起源与眼压测量研究有关,但当与圆锥角膜的治疗相关联时,其受到了更多关注,圆锥角膜是一种角膜力学特性发生改变的病症。由此确定了决定角膜稳定性的因素。屈光手术后也会利用角膜生物力学来研究术后角膜扩张,并改进忽略角膜反应的消融模式。新的消融系统需要纳入生物力学因素,这推动了在物理数学模型和角膜伤口愈合方面的研究,增进了我们对角膜生物力学反应的了解。
尽管角膜生物力学概念此前就已存在,但随着屈光手术的出现,其受到了更多关注。其相关性与旨在获得更准确可靠结果的消融系统的改进有关。
