What Happens During a Cataract Evaluation?
A cataract evaluation is a comprehensive eye exam designed to determine whether cataracts are affecting vision and how significantly they may be impacting daily life. It also helps identify whether other eye conditions may be contributing to symptoms such as blurry vision, glare, or difficulty seeing at night.
MERSI Exam Process
At MERSI, a cataract evaluation begins with a detailed discussion of vision concerns and medical history, followed by a full eye health assessment. This includes measuring vision clarity, evaluating how the eye focuses light, and assessing overall eye function to better understand the source of visual changes.
What Should You Expect During a Cataract Evaluation?
During the exam, patients typically undergo advanced diagnostic testing to evaluate both the lens and the retina. This helps determine whether cataracts are present and how much they may be affecting vision. The goal is to ensure an accurate diagnosis before any treatment recommendations are made.
Imaging and Dilation

Advanced imaging may be used to examine the internal structures of the eye in detail. In many cases, dilation is performed so the specialist can get a clear view of the lens, retina, and optic nerve. This step is essential for ruling out other conditions that can mimic cataract symptoms.
Discussion of Lens Options

If cataracts are present and treatment is appropriate, the evaluation may include a discussion of lens options and surgical considerations. This helps patients understand potential next steps based on lifestyle, visual needs, and overall eye health.
