Sažetak
The aim of this study was to compare the correlation of features of cataracts graded by the Lens Opacities Classification
System, version III (LOCS III) with recorded operative characteristics during the phacoemulsification. The retrospective
study included 245 cases operated on by a single surgeron from October 2003 to March 2004. The cataract was
graded at the biomicroscope using the 4 grading scales of the lens opacities classification sistem, version III (LOCS
III); nuclear opalescence (NO), nuclear color (CO), cortical cataract (C) and posterior subcapsular catract (P). We recorded
2 intraoperative characteristics: machine masured phacoemulsification time, and average machine power. The
machine recorded phacoemulsification time and average power correlated positively with the estimated nuclear color
(NC) scale and nuclear opaclescence (NO) scale. Grading within categories of cortical catract (C) and posterior subcapsular
cataract (P) did not correlate with any of the operative variables. Exponentially, greater phacoemulsification energy
was required as NC and NO increased. LOCS III grading system enables the surgeon to anticipate potential pitfalls
and to adapt the operative technique to the individual patient.
