Abstract
PURPOSE
To investigate the frequency of transient (1 month) and persistent (at least 6 months) postoperative ptosis following clear corneal sutureless phacoemulsification and to analyze the factors affecting them.
DESIGN
Cohort study.
METHODS
Patients who underwent phacoemulsification cataract surgery from October 2016 to June 2018 in a tertiary center were enrolled. Margin reflex distance 1 (MRD1), MRD2, and levator function were measured and facial photography was taken before, 1 month, and at least 6 months after the surgery. Clinical ptosis was defined as any postoperative drop of MRD1 and clinically significant ptosis as MRD1 drop of ≥2 mm. Photo-based ptosis was assessed by a masked oculofacial plastic surgeon at the end of the study.
RESULTS
A total of 234 patients (313 eyelids) were included. The majority of surgeries were performed by senior residents (65.5%, 205/313) and under topical anesthesia (78.0%, 244/313). Persistent clinical, clinically significant, and photo-based ptosis were 25.4% (71/279), 3.2% (9/279), and 3.3% (9/276). Eyelids with persistent postoperative ptosis showed a significantly (P = .03) lower preoperative levator function (13.9 vs 15.8 mm). No other factor was significantly different between the eyelids with and without postoperative ptosis.
CONCLUSION
Persistent clinically significant ptosis was observed in more than 3% of patients undergoing clear corneal sutureless phacoemulsification cataract surgery. It should be counseled preoperatively. Lower preoperative levator function was significantly associated with a higher frequency of postoperative ptosis. Duration of surgery, level of surgeons, and other variables did not have any significant effect on the frequency of postoperative ptosis.
