To verify the clinical usefulness of glare test and to measure contrast sensitivity function in patients with cataract.
Twenty eyes from 20 consecutive cataract patients were studied. Mean age was 64. 9 years. Ali were submitted to a complete ophthalmological examination and had their visual acuity measured using the Snellen Chart, the VCTS 6500 Chart ( Vistech Consultants, Inc.) and MCT 8000 ( Vistech Consultants, Inc.).
The results were converted to a MAR log scale and they showed that VCT 6500 and MCT 8000 are able to measure a change in the day and night visual acuity in patients with cataract.
The authors concluded that the two tests are valuable a uxilia ry to o ls when s uggesting phakectomy surgery in cataract patients with visual acuity ≥ 20140.
