JACOBOVITZ, Sérgio et al. Horizontal nucleofragmentation: a new technique for cataract surgery. Arq. Bras. Oftalmol. [online]. 2003, vol.66, n.3, pp. 365-368. ISSN 0004-2749. http://dx.doi.org/10.1590/S0004-27492003000300020.
PURPOSE: To study in vitro the efficacy of a pair of instruments designed to capture and split human nuclei obtained from extracapsular surgeries. METHODS: The sample is a compound of 47 cataract nuclei. They were classified as mature (4+) and immature (1 to 3+), and the visual acuity ranged from 20/60 to light perception. The instruments were used to split the nuclei. A methylcellulose over a gel base was made for this purpose. RESULTS: The average age was 67,38 years. Most patients (66%), had a visual acuity less than 20/400. 42,6% of the cataracts were mature. The capturing and splitting was easily done in over 90% of the nuclei. CONCLUSIONS: The designed instruments are effective to capture and split cataract nuclei.
