This technique is for use in eyes with mature or hypermature cataract resulting in lack of fundus reflex during capsulorhexis. Fluorescein staining is performed before the capsulorhexis is made. A blue filter in the coaxial light accentuates the remaining rim of bright blue fluorescence and aids in exact formation of the anterior opening. Seven eyes with a postoperative visual acuity of light perception had surgery using this technique. Visual acuity ranged from 20/200 to 20/20 up to 3 months postoperatively. No untoward reaction to the fluorescein was observed; however, the long ultrasound exposure for very hard nuclei (up to 4 minutes) caused corneal edema in two eyes. This technique is regularly used in all eyes with insufficient fundus reflex caused by lens opacity or vitreous disease.
该技术用于患有成熟或过熟白内障且在撕囊过程中导致眼底反射缺失的眼睛。在进行撕囊之前进行荧光素染色。同轴光中的蓝色滤光片可增强剩余的亮蓝色荧光边缘，并有助于准确形成前开口。七只术后视力为光感的眼睛使用该技术进行了手术。术后3个月内视力范围为20/200至20/20。未观察到对荧光素的不良反应；然而，对非常硬的核进行长时间超声照射（长达4分钟）导致两只眼睛出现角膜水肿。该技术常用于所有因晶状体混浊或玻璃体疾病导致眼底反射不足的眼睛。
