PURPOSE: Applied pre- and postoperative corneal topography outcomes with visual acuities were evaluated to determine the surgical results in pterygium therapy.
METHODS: The study group consisted of 30 eyes of 26 patients with primary and recurrent pterygium. Mean patient age was 52.26+/-11.50 years (range: 27 to 68 years). Pre- and postoperative visual acuity and comeal topography were evaluated for each case. Statistical analysis was performed using the repeated-measure test.
RESULTS: The mean uncorrected visual acuity was 0.41+/-0.30 preoperatively and 0.63+/-0.26 postoperatively (P<.001). The mean best spectacle-corrected visual acuity was 0.59+/-0.28 preoperatively and 0.84+/-0.22 postoperatively (P<.001). Surface regularity index ranged from 1.96+/-1.08 preoperatively to 1.09+/-0.76 postoperatively (P<.001). The mean surface asymmetry index was 3.05+/-2.85 preoperatively and 1.39+/-1.70 postoperatively (P=.003). The mean topographic astigmatism was 4.65+/-3.02 preoperatively and 2.33+/-2.26 postoperatively (P=.003).
CONCLUSIONS: Examination of the topographic records reveals pterygium-associated corneal flattening in the horizontal meridian along the line of the pterygium. The improvement in topographic pattern and best spectacle-corrected visual acuity can be used as one indicator of the success of pterygium surgery.
