[Comparative analysis of refractive and topographic changes after eyelid surgery].

Abstract

BACKGROUND\nThere is largely a\xa0lack of clarity on the question of whether refraction or topography changes are to be expected after blepharoplasty, levator resection, or a\xa0lateral tarsal strip procedure.\n\n\nMATERIALS AND METHODS\nTherefore, in the present study, objective refraction, anterior eye segment tomography, and visual acuity tests were carried out pre- and postoperatively in 78\xa0patients and then analyzed. The examination was carried out preoperatively, at suture removal after 10\xa0days, and after 3\xa0months.\n\n\nRESULTS\nNeither after blepharoplasty nor after a\xa0lateral tarsal strip procedure were significant changes in vision or refraction seen in the topography. In contrast, the Wilcoxon sign test 10\xa0days after levator resection showed a\xa0significant increase in the cylinder after 10\xa0days compared to the preoperative level (p\u202f=\u20090.042). However, this change was no longer detectable after 3\xa0months.\n\n\nCONCLUSION\nThe authors postulate that extensive patient education with regard to temporary visual changes, particularly in the case of levator resections, is essential and that additional refraction and topography control can be useful postoperatively.
