Pterygium is a degenerative condition of the ocular surface. The growth is known to cause issues such as visual blur or recurrent inflammation. It can also induce astigmatism and corneal aberrations.

In this column, we describe a patient who had an improved higher-order aberrations profile after pterygium excision.
