Has Snellen Chart Lost the Battle to ETDRS in Cataract Surgery Visual Acuity Evaluation?

description | This study was designed to explore practical differences between visual acuity (VA)
scores measured on Snellen chart versus ETDRS chart, to grade cataracts using LOCS III system, and
to compare VA on both charts depending on cataract grade and type. Prospective evaluation of uncorrected
and best-corrected visual acuity was carried out on the eye scheduled for cataract surgery preoperatively
and postoperatively on the Snellen and ETDRS charts. The study was carried out at Department
of Eye Diseases, Clinical Center of Serbia, during a two-year period. Inclusion criteria were
met by 540 patients who underwent testing, surgery, data collection and analysis. The mean VA score
was better on ETDRS than on Snellen chart. The mean difference was 6.05 letters or 1.21 lines. VA
results correlated with all types of cataract regardless of the chart used, with the highest statistical
significance (p<0.0001) for subcapsular cataract. The ETDRS chart was found to be more discriminative
and precise than Snellen chart, especially for poor VA. |
