Purpose: To grade the density of cataract objectively using a rotating
Scheimpflug camera and to investigate the correlation between the
grade of the density and the total phaco energies at the phacoemulsification.
Methods: In this study, one hundred eighty six eyes of
166 consecutive patients undergoing phacoemulsification for cataract
using Infinity (Alcon, US) by only one surgeon were preoperatively
examined with PENTACAM® (Oculus, Germany) and graded
into 5 grades according to the density and the area of the opacification
of lenses. The difference in the mean phaco energy between 5
graded groups was statistically analysed. Results: The numbers of
each grade were 59 (grade 1: G1), 63 (G2), 50 (G3), 7 (G4), 7 (G5).
The mean phaco energies were 4.28, 6.87, 7.34, 8.61, 8.93, (G1, 2, 3, 4,
5) and increasing as the grade was higher. In the group of the G1, the
mean phaco energy was statistically lower than any other groups
(from p < 0.001 to p < 0.05). Conclusion: The density of cataract was
able to be graded with the grading software in PENTACAM®, and the
mean phaco energy was increasing as the grade was higher. This
showed possibility that we could objectively evaluate the density
of cataract by using PENTACAM®.
