About this study

Eighty patients (80 eyes) with simple age-related cataracts were treated from December 2019 to December 2020 in the Wenzhou Medical University. Investigators specifically included patients who were bodily healthy and underwent a successful implantation of an IOL. Inclusion criteria for this study were patients who were older than 40 years old, had an axial length of 22-26mm, and could complete 4 follow-up visits.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

-patients who were older than 40 years old, had an axial length of 22-26mm, and could complete 4 follow-up visits.

Exclusion criteria

  • people cannot cooperate with the check， corneal opacity, glaucoma, and other eye diseases
  • any other previous intraocular surgery, and intraoperative complications including anterior or posterior capsulartears
  • Continuous circular capsulorhexis is not centered and Mydriasis is less than 7mm.

Treatment and study plan

Primary outcomes

  1. Capsular bend index (CBI)

    Time frame: 2020.12.1

    capsule bend formation has 5 continuous stages from 0 to 4，The stage score varies over different positions of the same capsule bag, because the capsule bend formation is inconsistent along the entire optic edge. CBI is the mean of the different stage scores in different positions and represents the general capsule bend state of the whole capsule bag.
