Study Details

Study Description

Brief Summary

This study will examine patient satisfaction and spectacle independence using a survey in patients who have undergone uncomplicated cataract surgery with a presbyopia-correcting lens at least 2 years prior to administration of the survey.

Condition or Disease Intervention/Treatment Phase
  • Other: Survey

Detailed Description

Purpose: To compare patient-reported satisfaction with a multifocal vs an accommodating presbyopia-correcting at least two years following implantation of either type of implant.

Number of study subjects: 200 (half with multifocal and half with accommodating lens implants)

In this study, we will send a secure, online questionnaire to patients who have previously undergone cataract surgery at least two years previously. Patients will receive an email invitation, and by clicking the embedded link and verifying their identity with date of birth and phone number, they will be directed to a survey. The survey will ask the following types of questions:

  • overall satisfaction with the surgery

  • would they do the same surgery again?

  • would they choose the same (elective) lens implant again?

  • for what types of activities (reading newspaper, driving, driving at night, fine print) do they require glasses to see clearly?

  • do they experience glare and halo symptoms?

  • how bothered is the patient by these symptoms?

These data will be stored on a secure server. Statistical analysis will be done by a statistician, using a student's t-test to determine statistical significance of any difference between patients with different types of lens implants.

No intervention will be planned with patients, other than analyzing the survey results. All patient identifying (demographic) information will be carefully protected according to HIPAA and HITECH standards.

Arms and Interventions

Arm Intervention/Treatment
Accommodating Lenses

Patients who underwent surgery with an accommodating lens implant.

Other: Survey

Multifocal Lenses

Patients who underwent surgery with an multifocal lens implant.

Other: Survey

Outcome Measures

Primary Outcome Measures

  1. Satisfaction [At least 24 months after cataract surgery was performed. No upper limit on time since surgery.]

    The patients will be asked to rate their satisfaction with their surgical results on a scale of "very satisfied", "satisfied", "neither satisfied nor dissatisfied", "dissatisfied", or "very dissatisfied".

Secondary Outcome Measures

  1. Ability to drive without glasses [At least 24 months after cataract surgery was performed. No upper limit on time since surgery.]

    The patients will be asked to rate their ability to drive without glasses on a scale of "very satisfied", "satisfied", "neither satisfied nor dissatisfied", "dissatisfied", or "very dissatisfied".

Eligibility Criteria
