Encouragement and motivation impact outcomes
In light of these issues, we performed a multicentre study to determine whether encouragement and motivation would have any significant impact on the outcome of the VA measurement using the standard Snellen chart after the initial reading of the test chart.11
Method
When the patient stated what he/she can read, the examiner tried to motivate and encourage the patient to read more, using the following prompts:
1. The patient was asked if he/she could read below the line that he/she stopped at initially.
Each patient's VA was measured three times. Firstly, unaided then with the assistance of spectacles and finally with pinhole. Results both without and with encouragement were recorded and all patients were informed and consented to the study. To investigate the statistical significance of motivation on the patients VA tests, we also applied paired t-test and P values to the results.

Evaluating the clinical performance of ZEISS AT ELANA and the new ’ELISA’* approach
July 30th 2025In this insightful analysis, Dr. Joong Hun Kim presents real-world clinical outcomes with bilateral implantation of ZEISS AT ELANA 841P. Dr. Kim recommends AT ELANA® 841P as an excellent option for patients undergoing cataract surgery as its fully trifocal optical design translates into a full range of vision. He also introduces the so-called ‘ELISA’ approach for patients requiring astigmatic correction in one eye only, combining AT ELANA 841P and ZEISS AT LISA tri toric 939MP. Early objective and subjective clinical data from this novel approach reveal promising visual outcomes and high patient satisfaction
