Primary outcome
Follow-up visits were conducted at 1 week and 1, 6 and 12 months. The primary outcome was the incisional cross-sectional area in TM that was quantified with AS-OCT (CASIA, Tomey, Aichi, Japan). The exact contralateral TM of the corneal incision area was set at 0°, and measurement points were set at 5° increments (five points; − 10°, − 5°, 0°, 5° and 10°) as shown in Fig. Five measurement points of an incision with AS-OCT. The exact contralateral trabecular meshwork of the corneal incision area was set at 0°, and measurement points were set at 5° increments (five points: − 10°, − 5°, 0°, 5° and 10°). The average of five measurement points was used in the analysis.
