PURPOSE
To describe the application of the light adjustable lens (LAL) using an intrascleral haptic fixation (ISHF) technique for the correction of aphakia and post-operative refractive error.
OBSERVATION
The LAL was placed using a modified trocar-based ISHF technique for visual rehabilitation following removal of bilateral cataracts in a patient with ectopia lentis. She ultimately obtained an excellent refractive outcome after adjustment with micro-monovision.
CONCLUSIONS AND IMPORTANCE
Secondary intraocular lens placement has a much higher risk of residual ametropia than traditional in-the-bag lens placement. The ISHF technique with the LAL presents a solution for eliminating postoperative refractive error in patients requiring scleral-fixated lenses.
目的
描述使用巩膜内触觉固定（ISHF）技术的可调节人工晶状体（LAL）在矫正无晶状体眼和术后屈光不正中的应用。
观察
在一名晶状体异位患者双侧白内障摘除后，采用改良的基于套管针的ISHF技术植入LAL以进行视力康复。经微单眼视力调整后，她最终获得了出色的屈光效果。
结论与意义
与传统的囊内人工晶状体植入相比，二期人工晶状体植入残留屈光不正的风险要高得多。LAL的ISHF技术为需要巩膜固定人工晶状体的患者消除术后屈光不正提供了一种解决方案。
