Purpose:
To investigate the efficacy of lutein and zeaxanthin combined with trypan or brilliant blue for anterior capsule staining to
facilitate capsulorhexis during cataract surgery.
Setting:
All surgeries were performed in Federal University of São Paulo, Brasil, in the ophthalmology department.
Methods:
In this study of 80 cadaveric eyes, cataract surgery was performed. Different lutein and zeaxanthin concentrations (0.01–20%) combined with different Trypan or Brilliant Blue concentrations (0.0125–0.025%) were tested in the anterior capsule. The various dye solutions were in contact with the anterior capsule for 30 seconds and then were removed by mechanical aspiration or membrane peeling. RESULTS Contact between lutein and zeaxanthin combined with trypan or brilliant blue and the lens surface resulted in a green staining of the anterior capsule, which facilitated surgical steps in all eyes. Lutein and zeaxanthin combined with trypan or brilliant Blue had strong affinity for anterior capsule. No dye solutions remained in the eyes after the membrane removal.
Conclusions:
A dye solution containing lutein and zeaxanthin combined with trypan or brilliant blue efficiently stained the anterior capsule in human cadaveric eyes and may be a useful tool for cataract surgery.
