Pterygium is known to cause corneal topographic changes that can result in decreased visual acuity. We present a case of recurrent pterygium causing blurred vision and diplopia, and document the corneal topographic changes, showing astigmatism of 15 diopters induced by lateral gaze, prior to surgical excision.
