In this prospective study the clinical results using three different small optic IOLs are presented. The best results were achieved in those cases with an anterior capsule rim overlapping the entire optic periphery. In those cases with sulcus fixation, haptic in/out and optic in/out positions a higher percentage of capsule fibrosis (Soemmering's rings) was documented (sulcus fixation: 100%, haptic in/out position: 75%, optic in/out position: 65.5%, bag: 7.3%). The fibrosis developed because of contact between the anterior and the posterior capsule leaf. These cases also showed decentrations of the intraocular lens (IOL) more often (sulcus fixation: 50%, haptic in/out position: 75%, optic in/out position: 34.5%, bag: 31.7%). Only one patient was disturbed by glare and halo phenomenons. Cellular reactions on the lens surface were moderate in most cases. Differences specific to lens type were found between the three IOLs implanted. The clinical results were comparable to the results of other comprehensive IOL studies. Under certain indication small optic IOLs represent an alternative to flexible implants for small incision surgery.
在这项前瞻性研究中，展示了使用三种不同小光学区人工晶状体的临床结果。在前囊边缘覆盖整个光学区周边的病例中取得了最佳结果。在那些采用沟内固定、襻进出位和光学部进出位的病例中，记录到更高比例的囊膜纤维化（索默林环）（沟内固定：100%，襻进出位：75%，光学部进出位：65.5%，囊袋内：7.3%）。纤维化是由于前后囊叶之间的接触而形成的。这些病例还更常出现人工晶状体（IOL）偏位（沟内固定：50%，襻进出位：75%，光学部进出位：34.5%，囊袋内：31.7%）。只有一名患者受到眩光和光晕现象的干扰。在大多数情况下，晶状体表面的细胞反应为中度。在所植入的三种人工晶状体之间发现了特定于晶状体类型的差异。临床结果与其他综合性人工晶状体研究的结果相当。在某些适应证下，小光学区人工晶状体是小切口手术中可折叠人工晶状体的一种替代选择。
