title: Fluorescein blue, light-assisted capsulorhexis for mature or hypermature cataract.
abstract: 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.
