| Abstract Background: Blepharoptosis is a drooping of the upper eyelid. The effect of ptosis surgery on corneal topography is debatable and needs to be identified. Aim of Study: To evaluate the corneal topographic changes after levator resection surgery in patients affected by congenital or acquired ptosis. Patients and Methods: This is a prospective study included 20 eyes with moderate to severe ptosis and a levator function range of 6-10mm and with the probability to be subjected to clinical examination and topographic investigations. Patients underwent between 14 to 20mm of transcutaneous levator muscle resection. The patients underwent complete ophthal-mological examination, routine lid examination for ptosis and corneal topography. Topographic parameters included K1, K2, astigmatic axis and power and pachy apex. Results: After surgical ptosis repair, corneal topography demonstrated a reduction in K1 of 0.12±0.28 diopters (D) which was non statistically significant, also k2 showed a reduction of –0.12±0.28 diopters (D) and that difference is not considered statistically significant. Regarding corneal astigmatism it increased by 0.02±0.29 diopters (D) and by measuring the p-value of that change it is not considered statistically significant. Both corneal astigmatism axis and pachy apex didn’t show statistically significant change. Conclusion: Correction of ptosis by levator muscle resec-tion increased corneal astigmatism six weeks after surgery with non-significant degree. | ||||
