SUMMARY

We evaluated visual acuity and keratometry variations in twenty one patients that underwent surgery for pterygium removal. Measurements were performed preoperative, 1 and 3 months after surgery.

Uncorrected visual acuity improved in 16 (76,2%) patients. Seventeen (81%) patients presented significant reduction of corneal astigmatism.

Further studies are necessary to better understand the effects of pterygium on visual acuity.

Key words: Visual Acuity; Keratometry; Pterygium Surgery; Astigmatism
