The Contact Lens Exam
Because contacts sit directly on the eye, you will need a few additional tests over and above your regular comprehensive eye exam to determine what type of lenses will work best for you. In addition to the usual tests, like a visual acuity test, a refraction, and an intraocular pressure test, we will assess your corneal health and measure your cornea for the proper fit.
Corneal Topography
We use corneal topography to map the surface and curvature of your cornea. It’s a non-invasive, computerized test that can reveal any possible issues with the surface of your eye, such as scarring or astigmatism. Corneal topography allows us to find the perfect fit of contact lens for your eyes.
Spectral Microscopy
Spectral microscopy, or a spectral microscope, is non-invasive imaging software used to take photographs of the corneal endothelium. This allows us to evaluate your cornea’s integrity to determine if your eyes are healthy enough for contact lens use. We can also assess your ocular health after extended lens use. Using this information, we can make adjustments in your contact lens type or brand to ensure your eyes remain healthy and comfortable while wearing contact lenses.
