  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Individuals must meet all of the inclusion criteria in order to be eligible to participate in the study. Men and women between ages 60 years and above with monofocal intraocular lenses bilaterally corrected for distance and +/- 0.5D sphere vision who need only +/- 2.5 D correction for reading. Given the age group selected only post menopausal women will be evaluated.

About this study

Official title: Effectiveness of Pilocarpine and Brimonidine to Improve Near Visual Acuity in Patients With Monofocal Intraocular Lenses

The current study aims to assess the use of pilocarpine and brimonidine to improve near visual acuity in patietns with monofocal intraocular lenses. Thirty-three subjects with be enrolled and baseline visual acuity with be measured at near and distance. This will be compared to visual acuity after drop administration over 6 hours. A quality of life questionnaire will also be evaluated.

Read the detailed description

This research study will try to find out if pilocarpine and brimonidine can help people with intraocular lens implants read without reading glasses. Thirty-three subjects will take part in this research study. Baseline visual acuity with be measured at near and distance. This will be compared to visual acuity after drop administration over 6 hours. A quality of life questionnaire will also be evaluated.All subjects will take part at Massachusetts Eye and Ear Infirmary (MEEI).

Being tested
Brimonidine, pilocarpine
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Brimonidine, pilocarpineDrug

    Also called Mirvaso; Alphagan P; Salagen; Isopto Carpine

    1 drop of pilocarpine (0.5%)

    1 drop of brimonidine (0.2%)

Study groups in NCT03825081
Study groupRoleWhat they receive
InterventionExperimentalInterventions will be the drugs: * pilocarpine - 0.5% * brimonidine - 0.2% One drop of each of the study drugs will be placed in the non-dominant eye and patient will be evaluated for adverse events. At hour 1 and 3 vision will be measured for distance at 20 ft and reading at 14 inches; pupil size will be measured and patient will be evaluated for adverse events. At hour 6 vision will be measured for distance at 20 ft and reading at 14 inches; pupil size will be measured; patient will be evaluated for adverse events; and quality of life/satisfaction survey (NEI RQL-42) will be given to patient.
Receives: Drug: Brimonidine, pilocarpine

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in visual acuity after administration of pilocarpine and brimonidine

    The primary aim of our study is to determine if the combination of pilocarpine and brimonidine improves near visual acuity in pseudophakic subjects 1 hour following drop placement, compared to baseline.

    Measured: baseline; hour 1

Secondary outcomes (1)
  1. Change in near and distance visual acuity

    Near visual acuity at 3 hours and 6 hours, distance visual acuity at 1,3, and 6 hours.

    Measured: baseline; hours 1; 3; and 6

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Brimonidine, pilocarpine in people with Presbyopia and Pseudophakia, run by Massachusetts Eye and Ear Infirmary at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 31 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Matthew Gardiner, MD (617-573-3202, Matthew_Gardiner@meei.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in visual acuity after administration of pilocarpine and brimonidine (time frame: baseline; hour 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jan 2019.
