Abstract:
Pars plana vitrectomy with encircling scleral buckling was performed for 30 eyes of 30 patients with complicated retinal disorders, and the changes of axial length, refractive power, and corneal curvature were analyzed. Significant axial length elongations were observed after encircling procedures. Mean elongation was 0.93+/-0.48mm after 3 months and 0.91+/-0.54mm after 6 months. These spherical equivalent of refraction showed myopic shift of -2.26+/-1.51 diopters(D) after 3 months and -2.19+/-1.39D after 6 months. These changes seem to be less prominent in the eyes with preoperative axial length of 24.50mm or longer(0.68+/-0.46mm after 3 months, 0.60+/-0.49mm after 6 months) than in the eyes with axial length of 24.49mm or shorter(1.18+/-0.35mm 1.23+/-0.38mm). Slight increase in astigmatism was observed, 0.80+/-1.35D after 3 months and 0.64+/-1.01D after 6 months. The mean keratometric readings showed no significant changes, 0.00+/-0.95D after 3 months and 0.26+/-0.95D after 6 months. The result of this study may give an important information when combined procedure of encircling scleral buckling and IOL implantation be planned.
