Efficacy of Pilocarpine 1% in Presbyopia

In this before-after interventional study on patients with presbyopia after cataract surgery, uncorrected distance vision and corrected distance visual acuity are measured and recorded by Snellen chart. Corrected near visual acuity from a distance of 40 cm is measured by the standard near vision chart (Rosenbaum near vision card). Twenty minutes after the administration of pilocarpine 1%, the corrected near and far visual acuity is measured again. Also, the relationship between the difference in average near visual acuity after the administration of 1% pilocarpine in pseudophakic people is measured with iris color and pupil size.
