Although the majority of aphakic patients will have intraocular lens implants (IOLs), there are several groups of patients for whom IOLs are not indicated. Synthetic keratophakia for the correction of aphakia has several inherent advantages over alternative forms of refractive surgery which use lathed corneal tissue. For example, the ability to produce a synthetic lens to precise specifications before surgery is a dramatic advantage over the use of lathed tissue lenses whose refractive properties cannot be determined until weeks or months after the lens is in place on the recipient cornea. Synthetic materials appear to behave in a predictable manner and are biocompatible. Both polysulfones and hydrogel materials can be used to correct aphakia in clinical situations where other modalities are less appropriate.
虽然大多数无晶状体患者会植入人工晶状体（IOL），但有几组患者不适合植入IOL。与使用切削角膜组织的其他屈光手术替代形式相比，用于矫正无晶状体的合成角膜移植术有几个固有优势。例如，术前能够生产出符合精确规格的合成晶状体，这比使用切削组织晶状体具有显著优势，因为切削组织晶状体的屈光特性要在其植入受者角膜数周或数月后才能确定。合成材料似乎表现出可预测的特性，并且具有生物相容性。在其他方式不太合适的临床情况下，聚砜和水凝胶材料都可用于矫正无晶状体。
