Abstract
Purpose : The purpose of this study was to evaluate the agreement of different methods on assessing toric lens rotation.
Methods : After fitting toric soft lens according to the manufacturer's guidelines at model eye and 57 eyes (average 24.79±1.29 years old), rotational evaluation was performed using a mobile phone photography, protractor application, portable magnifier and slit-lamp. Agreements among different methods and two testers were analyzed using Bland-Altman analysed.
Results : When the rotation amount of the toric soft lens was measured by the same rotation evaluation method with different testers, the average difference of the measured values was ?0.50, -0.70, -0.30 and ?0.13° showing similar results. Regarding the comparison of orientationevaluate methods, when using the mobile phone photography and protractor App, the measured values within the tolerance range were relatively low with 74.56% and 75.44%, respectively, and with the portable magnifier, the reliability was high with 95.61%.
Conclusion : Even if a slit-lamp can not be used in the prescription of a toric soft lens, clinically useful results for toric soft lens rotation evaluation can be obtained through photography, mobile phone protractor application and portable magnifier.
