Effect of Artificial Tears on Biometry

Impact of Lubrication With Artificial Tears on Biometry Measurements for Cataract Surgery

The purpose of this study is to determine if measurements for cataract surgery are improved with use of additional lubrication with artificial tears. The research study is being done to optimize measurements and provide patients with the best visual outcomes after cataract surgery.

Inclusion Criteria:

• Male or female ≥ 18 years of age
• Documentation of bilateral age-related senile cataracts diagnosis

Exclusion Criteria:

• Patients currently using regularly scheduled artificial tears. Patients with infrequent or irregular use of artificial tears may not be excluded from the study.
• Patients using contact lenses.
• Patients with any other surface pathology affecting corneal biometric measurements determined with slit-lamp examination or medical history.
