%X OBJECTIVE: To analyze the relationship between tear meniscus dimensions and higher-order aberrations (HOAs) in patients with lacrimal passage obstruction using anterior segment optical coherence tomography (AS-OCT).
METHODS: This study was a retrospective observational study of 71 eyes of 49 patients with lacrimal passage obstruction. These patients received sheath-guided dacryoendoscopic probing and bicanalicular intubation (SG-BCI) at Toyama University Hospital between August 2020 and October 2021. Using AS-OCT, tear meniscus height (TMH), tear meniscus area (TMA), and total corneal HOAs values were measured before and after surgery.
RESULTS: Surgical success was achieved in 69 eyes (97.1%). At the final observation, 62 eyes showed lacrimal patency (89.8%). The preoperative TMH, TMA, and HOAs values were 1.55 ± 0.96 mm, 0.11 ± 0.14 mm2, and 0.37 ± 0.27 µm, respectively, and the final postoperative TMH, TMA, and HOAs values were 0.97 ± 0.74 mm (p < 0.0001), 0.06 ± 0.11 mm2 (p = 0.02), and 0.29 ± 0.16 µm (p = 0.001), respectively. The results showed a significant improvement. The changes in HOAs before and after surgery were positively correlated with the changes in TMH (r = 0.3476, p = 0.0241) and TMA (r = 0.3653, p = 0.0174).
CONCLUSIONS: SG-BCI for lacrimal passage obstruction resulted in a significant decrease in measured HOAs. The decrease in HOAs was correlated with decreases in tear meniscus dimensions.
