ABSTRACT
PURPOSE:
This study was designed to evaluate the postoperative changes of astigmatism and corneal refractive power after surgical correction of epiblepharon using computerized topography.METHODS:
The surgical data were investigated retrospectively before surgery and 1 month, 3 month after surgery in 23 patients who had undergone surgery for epiblepharon. We evaluated 8 points of the corneal refractive index, the corneal center and nasal, temporal, inferior 1.0 and 2.0 mm and superior 1.0 mm respectively. And the incidences and types of astigmatism were evaluated before and after surgery.RESULTS:
After surgery, we observed corneal flattening at all points according to corneal topography, but corneal refractive changes were statistically insignificant except for inferior 1.0mm point (P< 0.05). Mean astigmatism was decreased after surgery and statistically significant 3 month after surgery (P< 0.05). Mean corneal refractive change on vetical meridian was prominent compared to horizontal meridia and statistically significant 3 month after surgery (P< 0.05).CONCLUSIONS:
In epiblepharon, children corneal topographic changes were observed due to reduction of corneal irritation and pressure by cilia and lower eyelid after surgery. Astigmatic changes were progressed 3 month after surgery and with-the-rule astigmatism was observed mainly before and after surgery. But corneal refractive changes were prominent on vertical meridian, and therefore there was a tendency toward improvement of with-the-rule astigmatism.
