Note: data accorded with normal distribution are presented as mean ± SD, and data not accorded with normal distribution are presented as median (P25 and P75). The difference was significant between two groups at postoperative 1h and 2h . Abbreviations: R: right eyes; L: left eyes, bo: before operation; po: postoperation, IOP: intraocular pressure, ACA: anterior chamber angle, TIA: trabecular-iris angle, AOD: angle opening distance, and PD: pupil diameter.
