Analysis of Corneal Topographic Changes after Upper Lid Surgery in Congenital and Acquired Ptosis

Objective: To assess the corneal topographic and refractive changes after ptosis surgery. Study Design: Prospective longitudinal study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi Pakistan, from Jan 2020 to Jul 2021. Methodology: A total of 90 individuals were selected by non-probability convenience sampling. Patients with diagnosed Ptosis and planned for surgery were followed up for six months post-surgery. Corneal topography, visual acuity, and physical assessment for Ptosis were done pre and post-surgery and compared for differences. Result: There were more cases of acquired Ptosis than congenital in our sample (p=<0.001). The patients had more poor levator function pre-operatively (p=0.291), which improved to fair post-operatively (p=<0.0001). Post-operatively, a significant decrease in the SimK and Cylinder power was observed in the sample. The visual acuity improved significantly, and the MRD also improved. With no significant change in CCT post-operatively. Conclusion: Our study showed that post-surgery SimK, visual acuity, MRD, and cylindrical power improved. However, the CCT did not show significant alterations.
