Added compatibility for iPads launched up to end 2022

Internal changes that do not affect to previous app performance

Added support to iPad 9th Generation (2021)

Added support to 2021 iPad devices

1.- Improved interface for new IOS versions. 2.- Corrected bug for statistical analysis section.

1.- Added compatibility of the Remote Control for IOS 14. 2.- Access to the Remote Control from iPad Pro account. 3.- Optimized the Remote Control performance.

Compatibility for iPad 8th and iPad Air 4 Generations added

Corrected error from version 3.0 related to import backups.

IMPORTANT!: Backup and export your database before updating - New statistics section for evaluating the average results for a particular protocol and filtering by the additional information of the exam. - iPad now can be also used as remote control in the Free version - The button bar can be moved to the left or right side of the screen for experimenters that do not use remote control. - Backups can be imported

The area under the defocus curve for total distance, far, intermediate and near calculated for each defocus curve.

PRO users: 1.- Included the "NA" (Not Available) possibility for pupil diameter selection in the Additional information. 2.- Corrected bug for which the App was closed during a backup if the protocol has not been assigned on any of the measurements.

Code optimization

Free Access updates 1.- Two possible distances (2 m and 4 m) 2.- Selecting a range of possible Defocus Lenses from +5.00 D to -5.00 D New PRO version with several options such as: 3.- Contrast Sensitivity Defocus Curve 4.- Optional steps of +/- 0.25D around de 0D step 5.- Sloan Optotypes (ETDRS) 6.- Auto-calculation of Sphere with Rx, Defocus and Distance 7.- Remote Control with another IOS device 8.- Historical Database to Store Defocus Curves 9.- Assign Defocus Curves to several Protocols (MIOLs or MCLs) 10.- Store Additional information (pupil, Rx, month, etc) 11.- Export Data to .CSV 12.- Calibrated considering several iPad models or the possibility of a personalized calibration. 13.- Export Defocus curve in a .png file by email 14.- Reverse the defocus curve plot from positive to negative or from negative to positive

1.- Added new psychophysical method in Premium area for research purpose. 2.- Possibility of attaching age, corneal power, IOL decentering and irregular astigmatism in the Premium area.

1.- Modified the psychophysical method for the contrast sensitivity defocus curve for improving the repeatability. The test now has a longer duration but only for contrast sensitivity defocus curves. 2.- Included in the preoperative measure the contrast sensitivity for an optotype size of 0.7 logMAR.

A new temporal label has been included in the top bottom alert of the defocus lenses for research purposes. This is a temporal change that does not affect any procedure from the previous versions.

Database information: •New additional fields in the edition of the exam in order to upload corneal aberrations and age of the patients. •Removed the information about the ETDRS visual acuity achieved by a subject at 3 m, 67 cm and 40 cm and the spherical refractive error by editing an exam. Style: •Subject list ordered by id. Now it is only possible to add users by a numeric identifier (no letters permitted). •Colors changed in buttons and labels in order to avoid glare in mesopic conditions. Application settings: •Positive contrast optotypes incorporated for measuring Visual Acuity Defocus Curves in mesopic conditions (driving at night). •New lower spatial frequency (optotype size) than the currently available in order to measure contrast sensitivity defocus curves. •Precise procedure removed from the settings because fast procedure has demonstrated a good agreement with ETDRS visual acuity measurement (results pending of publication).

Changelog 1.0.4 1.- Corrected Figure sizes on iPad Air. 2.- Improved psychophysical method, now is faster with the same reliability. Improvements in the Premium Area: 1.- You cannot create a subject that already exists in the database. 2.- An alert message appears before to remove a Subject or an Exam. 3.- Corrected bugs in database performance. 4.- Corrected the date of the exam. 5.- You can include the ETDRS visual acuity achieved by a subject at 3 m, 67 cm and 40 cm and the spherical refractive error by editing an exam. 6.- Colored circles appear at each defocus lens indicating the reliability of the measure (this is not yet validated). 7.- Exams before the 17 of May of 2016 cannot be edited.

Corrected bug: The default gammas load each time the App is restarted. New Update: Ensure that screen brightness is set at the standard value for each exam.

Changelog 1.0.2 1.- Gammas personalization for improving contrast optotype reliability. 2.- ButtonBar can be located at the right or left side of the screen. 3.- Question mark for pressing if the patient refers not seeing the optotype. 4.- “Come Back button” during the exam for coming back to the start window without finishing the exam. Improvements in the Premium Area: 5.- Message error when the examiner does not insert the correct username and password or when the iPad is not connected to internet. 6.- Contrast Optotype up to -1.9 log units for Contrast Sensitivity Defocus Curve. 7.- Figures have improved the dimensions. 8.- New variable for inserting in the database: “Time after surgery” which means the number of days, months, etc. when the measure is done after the surgery. 9.- When the experimenter has finished an exam through the Premium area, it goes back to the database and It is not required to login again.

1.- Visual Acuity Defocus Curve results figure corrected. It was incorrectly represented the range from -5.00 to 0 D and has been changed by -4.00 to +1.00 D. 2.- Labels for the Figure have been included. 3.- Facebook Support Group Link included. The Facebook support group has been created in order to enable the communication between users of the app. You can use this group to receive the most recent information about the app.
