Resumo: | IntroductIon: An appropriate evaluation cataract degree is essential for deciding to proceed with surgery. Our purpose was to study the relationship between objective metrics for quantifying age-related nuclear cataracts with visual impairment and phacodynamics parameters. Methods: Thirty eyes (30 patients) with age-related nuclear cataract were submitted to phacoemulsification. The average lens density (0 to 100) was evaluated by using a rotating Scheimpflug system (Pentacam HR, Oculus, Wetzlar, Germany) and the nuclear opalescence (NO) score was subjectively assessed using the Lens Opacities Classification System III (LOCS III). This different parameters were correlated with preoperative corrected distance visual acuity (CDVA) and cumulative dissipated energy (CDE). Results: The preoperative CDVA was correlated with the Scheimpflug-measured lens nuclear density value (r=0.617, p<0.01). The CDE was posi-tively correlated with the Scheimpflug-derived average density variable (r=0.681 p<0.01) than with LOCS III NO (r=0.661, p<0.01). Conclusion: The Scheimpflug-measured average density was correlated with subjective lens grading and preoperative CDVA. This metric also presented the highest positive correlation with phacodynamics. |

O objetivo foi estudar a relação entre parâmetros objetivos para quantificar cataratas nucleares relacionadas à idade com deficiência visual e parâmetros da facodinâmica. Métodos: Trinta olhos (30 pacientes) com catarata nuclear relacionada à idade foram submetidos à facoemulsificação. A densidade média da lente (0 a 100) foi avaliada usando um sistema Scheimpflug rotativo (Pentacam HR, Oculus, Wetzlar, Alemanha) e a pontuação de opalescência nuclear (NO) foi avaliada subjetivamente usando o Lens Opacities Classification System III (LOCS III). Estes diferentes parâmetros foram correlacionados com a acuidade visual corrigida para longe (CDVA) pré-operatória e energia dissipada cumulativa (CDE). Resultados: O CDVA pré-operatório apresentou uma correlação com o valor de densidade nuclear da lente medido por Scheimpflug (r=0,617, p<0,01). O CDE estava mais positivamente correlacionado com a variável de densidade média derivada de imagem de Scheimpflug (r=0,681 p<0,01) do que com LOCS III NO (r=0,661, p<0,01). Conclusão: A densidade média medida derivada da imagem de Scheimpflug foi corre- lacionada com a classificação subjetiva da lente e CDVA pré-operatório. Este parâmetro também apresentou a maior correlação positiva com a facodinâmica.
