HyperVOPTICA: Feasibility of Measurement of Optical Aberrations in Hyperopia by Using an Adaptive Optics Visual Simulator (AOVIS-I)
Study Details
Study Description
Brief Summary
The primary purpose of the protocol is to evaluate the adaptive optics visual simulator to measure optical aberrations in hyperopic eyes.
The study hypotheses are the:
-
Ability to measure optical aberrations in hypermetropia.
-
Knowledge of optical aberrations of the eye hyperopic.
-
To adapt therapeutic management in optical aberrations measured.

Detailed Description
The procedure is guided by the custom made software and its graphical user interface. The interface has been designed to be user-friendly, being very similar to the software usually managed by the clinicians in their daily professional practice. The complete procedure in one patient takes less than 5 minutes and is completely non-invasive. The optical measurements only involve the use of low power infrared laser and the visual testing is as simple for the patients as watching television and making responses.
