Official Title: Feasibility of Measurement of Optical Aberrations in Hyperopia by Using an Adaptive Optics Visual Simulator (AOVIS-I)

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 Summary: 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.

Current Primary Outcome: Measurement of optical aberrations [ Time Frame: 1 day (Participants will be followed for the duration of ophtalmology consultation) ]

Feasibility of Measurement of optical aberrations in hyperopia by using an Adaptive Optics Visual Simulator AOVIS-I. Outcome measure is assessed during a consultation


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Reproductibility of the measures [ Time Frame: 1 day (Participants will be followed for the duration of ophtalmology consultation) ]
    Evaluate the reproducibility of the measures obtained in hyperopic eyes. Outcome measure is assessed during a consultation
  • Quantitative measurement of optical aberrations [ Time Frame: 1 day (Participants will be followed for the duration of ophtalmology consultation) ]
    Expression of optical aberrations in numerical measures. Outcome measure is assessed during a consultation


Original Secondary Outcome: Same as current
