Brief Summary:
The main complaint of patients who received a presbyopia correcting lens (regardless of the design) are visual disturbances such as glare, halos (rings around lights), starbursts (rays around light sources), mainly at night. The degree of limitation or how bothered patients are varies from patient to patient. To explain these symptoms different theories have been proposed including splitting the light into different focal points which decreases the intensity of the light reaching the retina. Most factors are common to all patients who received the lens; however, patients are not equally affected by these symptoms. Angle kappa has been considered a factor. Angle κ is the angle between the visual axis (straight line that passes through both the center of the pupil and the center of the fovea) and the pupillary axis (perpendicular line to the surface of the cornea that passes through the center of the pupil).

Condition or disease Intervention/treatment
Pseudophakia Diagnostic Test: Angle Kappa Other: Visual disturbance questionnaire.

Study Type : Observational
Estimated Enrollment : 30 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of Angle Kappa and Different Intraocular Lens Calculation Formulas in Acrysof® IQ Panoptix Intraocular Lens Outcomes, Visual Disturbances and Patient Satisfaction
Actual Study Start Date : January 21, 2020
Estimated Primary Completion Date : January 31, 2021
Estimated Study Completion Date : April 30, 2021

Group/Cohort Intervention/treatment
Participants will receive the PanOptix intraocular lens.
Diagnostic Test: Angle Kappa
Angle kappa will be measured using the OPD III scan.

Other: Visual disturbance questionnaire.
Questionnaire evaluating visual disturbances.

Primary Outcome Measures :
  1. Effect of angle kappa in visual disturbances [ Time Frame: 3 months ]
    Angle kappa will be measured in microns. The value will be correlated to the presence of visual disturbances

Secondary Outcome Measures :
  1. Effect of angle kappa in patient satisfaction [ Time Frame: 3 months ]
    Angle kappa will be measured in microns. The value will be correlated with patient reported satisfaction
