The most popular method in clinical practice for evaluating the visual performance through the field with a Multifocal Intraocular Lens or a Multifocal Contact Lens is the Visual Acuity Defocus Curve. This application allows you to measure Defocus Curves with several advantages versus conventional charts.
The application is based on a Freemium model, just downloading the App you will have access to the following options:
1.- Visual Acuity Defocus Curves
2.- Two possible distances (2 m and 4 m),
3.- Selecting a range of possible Defocus Lenses from +5.00 D to -5.00 D
4.- Snellen optotypes.
BEFORE DOWNLOADING ON IPHONE YOU SHOULD KNOW:
The functionalities differ depending on the installation on an iPad or iPhone:
1.- You need an iPad for conducting the Defocus Curve measurement
2.- If you install the MLA in an iPhone this only serves as a remote control, you will still need an iPad to measure the Defocus Curve
3.- You can access to more information about the procedure at:
