The Outcomes of Involutional Ptosis Surgeries in a Single Tertiary Center.

PURPOSE: To report the surgical outcome of anterior approach primary ptosis surgery in a tertiary center and to compare redo surgical rates between different grades of surgeons.

METHODS: This is a Retrospective review of series of annual audits. All involutional/aponeurosis-disinsertion ptosis surgeries performed at Moorfields Eye-hospital (MEH) between January 01, 2016 and December 31, 2019 were included. Only primary surgery was included. The following data were collected; number of surgeries per year, number of patients, demographics data, grades of surgeons, success rate, redo surgery rate from different grades of surgeons, complications rate and patients' satisfaction.

RESULTS: During the study period, 1191 ptosis surgery were performed, with 899 (75%) cases being involutional/aponeurosis-disinsertion ptosis. The mean redo surgery rate within one year from the primary surgery was 10.5% and the mean complication rate was 1.0%, with 78.95% of patients reported being satisfied with the results of the surgery, having no difference between surgeon's grades. The redo surgery rate was higher for cases performed by a junior surgeon (fellow/registrar) (64.26%) than by a consultant (38.94%).

CONCLUSIONS: We report the success rate of a large cohort of primary involutional ptosis surgery performed at the ophthalmic-specialist tertiary center. The success and complication rates are comparable to the literature at 90% and 1%, respectively. Redo surgeries were more frequently required when performed by junior surgeons compared to the consultants, whereas the patient satisfaction level did not differ between different grades of surgeons.
