- Observational non invasive
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Retinal sensitivity thresholds, measured by means of perimetry, as a function of ocular aberrations.
- Secondary Outcome Measures
Name Time Method Change in retinal sensitivity thresholds, measured by means of perimetry, as a function of ocular aberrations before and after clear lens extraction in PAC patients<br /><br><br /><br>Other<br /><br>Corneal aberrations, ocular biometry, ocular scatter, intraocular pressure, visual acuity and refraction. Cases and controls are matched for age and gender; visual field damage and refraction are used for descriptive statistics, to characterize the study population.
