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).

Inclusion Criteria:

• 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.

Exclusion Criteria:

• Individuals meeting any of the exclusion criteria at baseline will be excluded from study participation including: allergies to proparacaine, pilocarpine or brimonidine, eye infection or inflammation, glaucoma, retinal tear or retinal disease, eye surgery within the past 30 days, use of eye drops within the last seven days, participated in any other research study within the past 30 days.
