Eligibility Criteria
You may qualify if:
- Primary open-angle glaucoma patients with cataract in our Ophthalmic Center;
- Topical use of hypotensive drugs in the treatment of poor or intolerable intraocular pressure control;
- The patients were aged from 50 to 80 years old, regardless of gender;
- Class operation and phacoemulsification were performed;
- Patients are able and willing to comply with the research guidance and may complete all visits required by the research;
- Informed consent has been signed.
You may not qualify if:
- Allergic to any perioperative medication in this study;
- History of ocular trauma;
- Any previous intraocular surgery;
- Angle of the chamber was narrow by angle microscopy (Schaffer grade III and below);
- Patients diagnosed as secondary glaucoma;
- Optic atrophy caused by other reasons;
- The serious complications such as posterior capsule rupture and choroidal hemorrhage occurred during the operation;
- Serious complications of eyes occurred after operation;
- The patient's history indicated that he had severe dysfunction of heart, lung, liver and kidney;
- Women in pregnancy, lactation or planned pregnancy;
- The researchers believe that the patient's condition may put the patient at significant risk, and may confuse the research results.
