Objective: Surgical repositioning of the eyelids may change
astigmatism. The change in astigmatism may affect the results
of previous refractive procedures.
Material and Method: Twenty-eight eyes of 18 patients were
included in the study. Interpalpebral fissure height (IPF), margin
reflex distance 1 and 2 (MRD 1-2), and levator function (LF) were
recorded in all patients preoperatively and at the postoperative
third month. Keratometric values were measured by Scheimpflug corneal topography. Surgically induced astigmatism values
due to upper eyelid surgery were calculated using a vectorial
Results: The mean age of the patients was 45.46±18.8 years.
Blepharoplasty was performed in 11 eyes with dermatochalasis.
Levator resection was performed in nine of 11 eyes with ptosis,
and frontalis suspension was performed in the remaining two
eyes with ptosis. Blepharoplasty with levator resection was performed in six eyes where ptosis coexists with dermatochalasis.
There was no significant difference between preoperative and
postoperative keratometric and LF values. However, there was
a significant increase in IPF and MRD 1 values. Mean surgically
induced astigmatism was 0.54±0.22 D.
Conclusion: Upper eyelid surgery can induce astigmatism.
Therefore, it might be better to perform upper eyelid surgery
before refractive procedures.
