“…[28,46]). Errais et al recently demonstrated that the astigmatism in 20 eyes with pterygium, treated with surgical excision, was reduced from 5.47 ± 3.45 D to 1.79 ± 1.52 D and BCVA increased from 0.73 ± 0.20 to 0.89 ± 0.16 [17]. Bahar et al, in a similar study of 55 eyes with primary pterygium, came with almost the same results.…”

“…Even without involvement of the optical zone, pterygium can produce significant alterations in corneal shape and curvature. Thus, many studies have shown that pterygium is associated with regular and irregular astigmatism as well as changes in corneal curvature and refractive status, which improve at least in part after the surgery [1][2][3][4][5][6][7][8][9][10][11][12][13]. Corneal curvature in these studies has been investigated with corneal topography, which evaluates the front corneal surface.…”

“…1 Contrary to our results, some studies show no correlation between these 2 parameters. 19,20,21 ,This contradiction might be related to the larger horizontal pterygium sizes in present study In conclusion, pterygium results in high corneal astigmatism, which increases with the increase in horizontal length, and decreases to an acceptable level following excision. We found a significant correlation between the preoperative and postoperative astigmatic values as well as the changes in astigmatism with surgery…”

AIMS:To review the effect of surgery type on the postoperative recovery & astigmatism in pterygium surgery. SETTINGS AND DESIGN: Randomized comparative clinical trial. MATERIALS AND METHODS: Forty six patients (46 eyes) with primary pterygium were randomised to undergo pterygium surgery using either autologous fibrin glue (23 eyes) or 10-0 nylon sutures (23 eyes) to attach the conjunctival autograft. The patients were followed up 1day, 1wk, 2wks & 6 weeks. Outcome measures were keratometry changes & postoperative recovery.. The preoperative and postoperative keratometric measurements, evaluated using keratometer, were noted. RESULTS: Corneal astigmatism was significantly reduced in the total group from 2.94(SD-0.52) diopter to 1.91 (sd 0.57) diopter (p < 0.001) The reduction in astigmatism was not significantly different between the two groups In the autologous fibrin glue group, the mean operation time was13.96 (SD 3.2) min (range 10-20 min) and in the suture group (p<0.001) it was 29.78 (SD 4.6) min (range 20-35 min). One patient in each group had partial graft dehiscence; it was successfully reattached with autologous fibrin / sutures accordingly (p>0.05).The intensity of the postoperative watering, itching, were significantly lower in the autologous fibrin glue group than in the suture group (p<0.001). Postoperative redness was absent in 47.82% (11cases) and mild in 52.18% (13 cases) 2 weeks postoperatively in the autologous fibrin group while in sutured group 17.4% (4cases) had mild redness and 82.6% (19 cases) had moderate redness 2weeks postoperatively. CONCLUSION: Corneal astigmatism is reduced by

Effect of Pterygium Surgery on Corneal Topography

Abstract: Corneal topographic changes caused by the pterygium are almost reversible after surgical treatment. Successful pterygium surgery significantly reduces topographic astigmatism, SRI, SAI, and corneal flattening. However, precise prediction of these refractive changes is not always accurate.
