Purpose
We analyzed the corneal topography before and after blepharoptosis surgery and examined whether there was a difference in the corneal topographic changes with and without deepening of the upper eyelid sulcus (DUES).
Study design
Retrospective study.
Methods
A total of 23 eyes of 23 patients (6 men and 17 women) were enrolled in this study. The patients were divided into two groups according to the presence or absence of DUES, and their clinical characteristics were compared.
Results
There were no significant differences between the DUES (n = 9) and non-DUES (n = 14) groups in any of the parameters examined before blepharoptosis surgery, including age, best-corrected visual acuity (BCVA), margin reflex distance-1 (MRD-1), spherical equivalent, average keratometry (AveK), cylindrical power (CYL), corneal higher order aberrations (HOAs) and central corneal thickness (CCT). In the non-DUES group, BCVA, spherical equivalent, AveK, CYL, and CCT were not significantly different between before and after surgery. On the other hand, in the DUES group, BCVA, spherical equivalent, and CCT were not significantly different before or after surgery, however, AveK, CYL and HOAs showed significant decreases after surgery. In addition, related to the post-surgical changes in CYL, the DUES group had a higher rate of reduced CYL.
Conclusion
It is expected that in eyes with DUES blepharoptosis surgery can reduce AveK, CYL and HOAs in association with postoperative corneal flattening, and that will contribute to improvements in visual function.
