Ophthalmology and Optometry

​​​​​​​​​​​​​​​​​​​​​​​Marshfield Clinic Ophthalmologists and Optometrists specialize in the prevention, diagnosis and treatment of vision problems and eye diseases.

Optometrists provide regular eye examinations to identify vision problems. They check for vision problems such as nearsightedness, farsightedness and astigmatism. Optometrists also check for other eye conditions or diseases.

Ophthalmologists are medical doctors who diagnose and treat diseases of the eye. They also perform surgical procedures to correct conditions and disorders of the eye. Ophthalmologists perform LASIK eye surgery​.

Using medical, laser and surgical methods we are able to treat:

  • Glaucoma
  • Retinal diseases
  • Corneal and external eye diseases
  • Eyelid and eye watering problems
  • Orbital diseases
  • Vision problems requiring glasses or contact lenses

Common eye conditions

The most​ common eye conditions include:

​Myopia - nearsightedness

Myopia is nearsightedness. It occurs when the cornea is shaped too steeply or when the eyeball is too long. This means that the light entering the eye is focusing at a point in front of the retina instead of on the retina. A myopic eye can see near objects clearly. Distant objects are seen more clearly only with the aid of glasses, contact lenses or procedures such as laser vision correction.

​Hyperopia - farsightedness

Hyperopia is farsightedness. It occurs when the cornea is too flat centrally and steeper at the edges. This means the images focus beyond the retina. In our youth, the natural accommodating (focusing) power of the eyes often compensates. As we age, our eyes become less able to accommodate. Farsightedness can be reduced or eliminated by glasses, contact lenses, or procedures such as laser vision correction, by making the central part of the cornea more steeply curved.


Astigmatism is a condition that occurs when the cornea is not perfectly round/spherical like a basketball, but has two curvatures much like a football. This results in light rays not coming into a single focus. A blurred distorted image then occurs. Astigmatism can occur by itself or in combination with nearsightedness or farsightedness.
