Summary
Upper eyelid gold weight implantation increases corneal astigmatism, primarily affecting the vertical axis. This change is reversible upon removal of the gold weight, offering a potential solution for managing astigmatism.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Facial nerve palsy can lead to eyelid dysfunction.
- Upper eyelid gold weight implantation is a surgical option to correct eyelid closure issues.
Purpose of the Study:
- To assess the impact of upper eyelid gold weight implantation on corneal astigmatism.
- To determine if astigmatism changes are reversible after gold weight removal.
Main Methods:
- Prospective cohort study involving 18 patients undergoing upper eyelid gold weight implantation.
- Corneal topography was performed before and after implantation, and after removal in nine patients.
Main Results:
- A significant increase in with-the-rule corneal astigmatism (1.4 D) was observed post-implantation (p=0.034).
- Following gold weight removal, corneal astigmatism decreased by 1.2 D, though this was not statistically significant (p=0.136).
Conclusions:
- Upper eyelid gold weight implantation induces an increase in corneal astigmatism, mainly in the vertical meridian.
- The induced astigmatism appears to be reversible upon the removal of the gold weight.
