低至12~ 15mmHg ，並與正常人的眼壓相較也降低至正常值範園，與國外臨床量測相似， 並且模擬術
化手術做為隅角閉鎖型青光自民的第一線治療的依據。 The efficiency of phacoemulsification surgery has been excellence for the treatment of angle closure
glaucoma in recent years. Therefore, these simulations were focused on situation before and after
phacoemulsification surgery. Phacoemulsification cataract surgery is an intraocular lens implantation surgery
which is followed by destructing cloudy lens into tiny pieces by ultrasound or emulsification then removes it.
This study is based on numerical simulation method to explore pressure of external vitreous and posterior
chamber changes, and compared results of pressure difference between before and after the
phacoemulsification surgery for the treatment of angle closure glaucoma.
According to simulated results of this study, the pressure reduced to a health intraocular pressure range
after phacoemulsification surgery, these simulated preoperative and postoperative intraocular pressure
transmission results are similar to foreign clinical studies; this research is sometimes difficult to achieve in
the clinical, and this study provided an approval for use of phacoemulsification surgery as the first treatment of angle closure glaucoma.
