OBJECTIVE-To evaluate changes in visual acuity and corneal topography in pre and post pterygium surgery patients.
METHODS- It was a prospective study in which time course changes in visual acuity and corneal topography were measured using placido-based principle sirius machine preopatively and in postop cases at 1 and 3 months interval.
RESULTS-Study included 52 eyes that underwent excisions of primary pterygia. Examination included Snellen’s visual acuity, manifest refraction, slitlamp and corneal topographical examination in pre and postop cases.Pterygium was graded as: grade I-crossing limbus, gradeII- midway between limbus and pupil, gradeIII-reaching pupillary margin, gradeIV-crossing pupillary margin.The increasing size of pterygia correlated significantly with astigmatism, surface irregularity and asymmetry.Best-corrected visual acuity and size of pterygium correlated inversely.
CONCLUSION-pterygium surgery reduces pterygium-induced astigmatism and improves visual acuity slowly.
