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.
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).

RECRUITINGChange 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.
Time frame: baseline; hour 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.
Time frame: baseline; hours 1; 3; and 6
