Study Population

Included in Eye Hospital of Wenzhou Medical University for "phacoemulsification combined with intraocular lens implantation" 2 hours after using a non-contact tonometer (FT-1000, TOMEY, JAPAN) to check that the intraocular pressure exceeds 28mmHg accompanied by corneal edema, anterior chamber radiation and age-related cataract patients over 60 years of age is required.

Description

Inclusion Criteria:

  1. Patients over 60 years old who underwent simple age-related cataract surgery in Eye Hospital of Wenzhou Medical University, the operation was successful, and there were no intraoperative complications such as posterior capsule rupture;
  2. Measurements were taken before and after drainage, and all data were complete ;
  3. The patient agrees and accepts the study.

Exclusion Criteria:

  1. Preoperative glaucoma, ocular hypertension, iritis, uveitis and other eye diseases, as well as other eye diseases and serious systemic diseases that may affect the prognosis of surgery, such as corneal lesions, vitreous volume blood, retinal detachment, poor blood sugar control in diabetes, etc.
  2. Previous history of eye trauma, etc.
  3. Cannot cooperate with the completion of intraocular pressure measurement and CASIA2 examination.
