The study objective is to assess changes in corneal sensation and dry eye signs and symptoms following cataract extraction/femtosecond arcuate relaxing incisions.
Our clinical hypothesis is to determine if a combination of cataract surgery and femtosecond arcuate relaxing incisions lead to a reduction in corneal sensation and the onset or worsening of dry eye signs and symptoms.

- Change in Corneal Sensitivity Testing [ Time Frame: Change from Screening to Month 3 ]Subject lies supine with the test line of the Cochet-Bonnet Aesthesiometer suspended over the cornea to measure the sensation of touch on the eye. Testing is done in a standard manner by an experienced operator.
- Ocular Surface Disease Index (OSDI) [ Time Frame: Change from Screening to Month 3 ]Subject questionnaire
- Subject Dry Eye Questionnaire [ Time Frame: Change from Screening to Month 3 ]Subject questionnaire
- Artificial Tear Use [ Time Frame: Change from Screening to Month 3 ]Subject questionnaire
- Corneal and Conjunctival Staining [ Time Frame: Change from Screening to Month 3 ]Clinical assessment of Dry Eye severity on the cornea via the use of fluorescein dye and on the conjunctiva via the use of lissamine green dye.
- Tear Break Up Time (TBUT) with Biomicroscopy [ Time Frame: Change from Screening to Month 3 ]Clinical assessment of Dry Eye severity via Biomicroscopy with fluorescein dye
- Best Corrected Visual Acuity (BCVA) [ Time Frame: Change from Screening to Month 3 ]Best Corrected Visual Acuity via eye chart examination
- Intraocular Pressure (IOP) [ Time Frame: Change from Screening to Month 3 ]Intraocular pressure via slit lamp examination
