Abstract Purpose:Recently, three-dimensional heads-up surgery(HUS)has been increasing used, especially in vitrectomy and cataract surgeries. However, little is known about blepharoptosis surgery using HUS. In this study, we report our experience with the HUS-assisted blepharoptosis surgery compared to regular microscopic surgery.

Participants and Methods:Forty eyes of 20 patients diagnosed with involutional blepharoptosis were age and gender-matched and equally divided into two groups that underwent blepharoptosis surgery using HUS(NGENUITY®, Alcon)or a regular microscope(MS). The total operation time(T1), incision(T2), levator resection(T3)and closure(T4)were step-wise compared between the two groups. According to the use of the green filter, the HUS group was further divided into two subgroups and the corresponding parameters were compared. Further, a self-assessment questionnaire survey was conducted for intraoperative pain and microscopic light dazzle(visual analog score, VAS). The lid swelling score(VAS)and, the improvement of MRD1 at 1 month following surgery were also investigated.

Results:The T1, T2, T3 and T4 were 21.5±4.2 min, 6.7±3.9 min, 3.61±2.62 min, and 9.4±5.7 min for the HUS group and 13.8±2.6 min, 3.2±0.88 min, 3.15±1.7 min and 5.35±2.61 min for the MS group. The T1, T2, T4 showed significant differences between the two groups(p=0.014, p=0.002 and p=0.01, Student t-test). For HUS, the green filter subgroup showed significantly decreased surgical time of T1 and T2 compared to no-filter subgroup(p=0.016 and p=0.007). There was no significant difference in intraoperative pain, intraoperative light dazzle, postoperative lid swelling and improvement of MRD1 between the two groups.

Conclusions:Although HUS-assisted blepharoptosis surgery is time-consuming compared to regular microscopic surgery, the application of green filter can be beneficial for increased visibility of the surgical field and hence contribute to shortened surgical time.
