Abstract Facial feminization surgery (FFS) improves gender dysphoria. The brows and eyes are crucial in perceived gender, yet brow and eyelid surgeries are relatively underutilized. This study aimed to determine rates of brow and eyelid surgeries as part of FFS and characterize pre- and postoperative periocular features. We conducted a retrospective review to identify all patients with the diagnosis of gender dysphoria who underwent FFS at a single academic institution from 2019 to 2022. Thirty-four patients comprising 38 surgical cases were included. Twelve (35%) eyelid surgeries and 27 (79%) brow lifts were performed. Baseline eyelid measurements did not differ between brow lift and nonbrow lift cases. Those undergoing brow lift and eyelid surgery were older in age (p = 0.022), had a higher rate of negative canthal tilt (p = 0.050), and smaller baseline margin-reflex distance 1 (p = 0.014) than patients who had brow lift alone. Brow lift increased tarsal platform show (p ≤ 0.001) and lash-to-brow distance (p ≤ 0.001), and upper blepharoplasty increased tarsal platform show (p = 0.01). Rates of brow lift are high at our institution, and patients are appropriately selected for eyelid surgery in FFS. Brow lift and upper blepharoplasty can feminize anatomical features when using standards described for cisgender cohorts. The impact of periocular features on gender perception in transgender patients warrants further study.

Précis: Damage to disposable selective laser trabeculoplasty (SLT) lenses correlated with the amount of total laser energy. Furthermore, greater lens damage was associated with diminished patient treatment response. Purpose: Disposable SLT lenses have been observed to be damaged during use by laser, potentially affecting therapeutic response. This study sought to identify factors associated with the magnitude of lens damage and its effect on treatment outcomes. Patient and Methods: We analyzed 113 eyes from 82 patients who underwent SLT between 2020 and 2021 at an American academic medical center. For each procedure, we recorded baseline patient characteristics, procedure settings, physician age (as a possible factor causing laser defocus due to accommodation), and area of lens damage. Treatment response was calculated as the difference between preoperative and postoperative intraocular pressure (IOP). Results: Area of lens damage was associated with greater total laser energy (r=0.34, P<0.001) and greater mean energy per application (r=0.37, P<0.001). IOP reduction decreased with increasing lens damage (r=−0.19, P=0.022). Lens damage was not associated with patient characteristics indicative of glaucoma severity or user settings (physician age and slit lamp used). Greater IOP reduction was associated with higher preop IOP (r=0.46, P<0.001) and a smaller cup-to-disc ratio (r=0.22, P=0.036). IOP reduction was not associated with retinal nerve fiber layer thickness, patient age, or the number of glaucoma medications. Conclusions: Increased laser damage to disposable SLT lenses was associated with diminished treatment effect. The amount of damage was correlated with total and average laser energy, but not patient or physician factors. Overall, these findings call for reconsideration of using disposable SLT lenses as part of routine practice.
