Useful Prediction of Phacodynamics by Scheimpflug Lens Densitometry in Patients over Age 70.

Abstract:

PURPOSE:To evaluate the relationship between lens density using the Scheimpflug system and phacodynamics in nuclear cataracts as related to patient age. METHODS:In 262 eyes with nuclear cataracts, the objective lens density was determined by Pentacam Nucleus Staging (PNS) software while subjective grading was achieved using the Lens Opacities Classification System III (LOCS III). RESULTS:Overall, cumulated dissipated energy (CDE) had a positive correlation with Scheimpflug lens density and LOCS III nuclear scores. When analysis was done by patient age, LOCS III nuclear scores and Scheimpflug lens density had a positive correlation with CDE for patients in all age groups. Of interest, patients >70 years old showed a higher correlation coefficient (r) with Scheimpflug lens density than with LOCS III nuclear score. CONCLUSIONS:Scheimpflug lens densitometry may be more useful for predicting phacodynamics than LOCS III scores in nuclear cataract patients, especially in old age (>70 years).
