Objective:

Determine the relationship between subjective lens opacity classification by LOCS III, best corrected visual acuity and objective visual quality analysis by aberrometry.

Methods:

A cross-sectional observational descriptive study was conducted based on LOCS III to classify senile cataracts in patients with visual acuity above 0.7 and objective visual quality measurement by wavefront analysis attending the Ocular Microsurgery Center of Ramón Pando Ferrer Cuban Institute of Ophthalmology from June 2016 to December 2017.

Results:

Cortical cataracts were associated to a large number of higher-order ocular aberrations, mainly coma and trefoil. Significant spherical aberration values were also found in the nuclear cataract group. Cataracts in the posterior subcapsular group did not display a prevailing aberration type. It was not possible to determine the relationship between the magnitude of the cataract as classified by LOCS III and visual quality indicators or best corrected visual acuity, because sample size was insufficient to be related to the large number of categories in LOCS III.

Conclusions:

In patients with senile cataract and good visual acuity, the type and degree of opacity as classified by LOCS III determines the type and magnitude of the aberrations, and thus the deterioration of visual quality.
