A patient with bilateral aniridia and progressive congenital cataract was treated at the age of 7 years through phacoaspiration with femtosecond laser capsulotomy, in-the-bag intraocular lens implantation, and pars plana vitrectomy (combined with posterior capsulotomy). The diameter of the planned anterior capsulotomy was 4.7 mm; however, due to elevated tension in the young capsular bag, the capsulotomy diameter increased (to around 6 mm) shortly after release of the tension by the laser. In addition, the patient had a very flat and small cornea, causing the formation of air bubbles in the curved laser interface. This was addressed by filling the gap by using a viscoelastic. A very similar situation was observed in both eyes. Use of the femtosecond laser facilitated a successful outcome in a complex congenital cataract case with a safe capsulotomy that ensured in-the-bag intraocular lens placement.
一名患有双侧无虹膜和进行性先天性白内障的患者在7岁时接受了治疗，采用飞秒激光晶状体囊切开术、囊袋内人工晶状体植入术和平坦部玻璃体切除术（联合后囊切开术）进行超声乳化。计划的前囊切开术直径为4.7毫米；然而，由于年轻囊袋内张力升高，在激光释放张力后不久，囊切开术直径增大（至约6毫米）。此外，患者角膜非常扁平且小，导致在弯曲的激光界面形成气泡。通过使用粘弹性物质填充间隙解决了这一问题。两只眼睛都观察到了非常相似的情况。飞秒激光的使用在复杂先天性白内障病例中促成了成功的结果，实现了安全的囊切开术，确保了囊袋内人工晶状体的植入。
