What a Cataract Evaluation Covers

A cataract clouds the eye’s natural lens over time, gradually reducing clarity, contrast, or night vision. When you visit SharpeVision in Bellevue or Renton for a cataract evaluation with Dr. Schmitz, the appointment focuses on two core questions: how much of your visual difficulty comes from the cataract itself, and which surgical and intraocular lens plan fits the rest of your eye.

Rather than starting from a generic menu of lenses, the evaluation examines corneal shape and tear film stability, retinal health, optic nerve status, eye pressure, and any history of prior laser vision correction or eye surgery.

Key Factors That Shape Your Surgical Plan

  • Intraocular Lens Selection & Visual Targets: Comparing monofocal, toric, extended depth of focus (EDOF), and multifocal lens designs based on the distances you use most—such as night driving, computer work, or reading—and your willingness to wear glasses for certain tasks.
  • Coexisting Glaucoma or Elevated Eye Pressure: Evaluating optic nerve health, visual fields, and target eye pressure to determine which lens optics are appropriate and whether cataract surgery alone or a combined glaucoma procedure (such as MIGS) should be discussed.
  • Prior LASIK, PRK, or Corneal Surgery: Accounting for previous corneal reshaping with specialized biometry and post-refractive lens calculation methods, while setting realistic expectations for target accuracy.
