Purpose

Validation of the Easee web-based tool for the assessment of  visual acuity in patients who underwent cataract surgery. 

Setting

A single-center prospective hospital-based validation study, carried out in the University Eye Clinic Maastricht UMC+.

Methods

Subjects, aged between 18 and 69 years old who underwent cataract surgery on one or both eyes at the Maastricht University Medical Center+, were eligible to participate in this study. The uncorrected and corrected visual acuity assessments were performed using the Easee web-based tool (index-test), and conventional Snellen and ETDRS visual acuity charts (reference tests). The outcomes of the different tests were expressed in logMAR and a difference of ≥0.15 logMAR was considered clinically relevant.

Results

A total of 46 subjects with 75 operated eyes were included in this study. The difference between the measurements of the Easee web-based tool and the ETDRS chart had a value of -0.05±0.10 logMAR (p-value= 0.000; [0.15:-0.26]), and -0.04±0.08 logMAR (p-value 0.000; [0.13:-0.21]), for the uncorrected and corrected distance visual acuity, respectively. The Pearson correlation coefficients between these tests were for the uncorrected and corrected visual acuity measurements respectively, 0.94 and 0.89. In total, 82.9% to 88.2% of the visual acuity measurement differences were within the clinically acceptable range.

Conclusion

The Easee web-based tool can be validated for the assessment of visual acuities in patients who undergo cataract surgery when considering a difference of ±0.15 logMAR as clinically acceptable. Future studies need to be conducted to assess the applicability of this tool in regular cataract care.
