LZL nucleus density

Details and patient eligibility

About

To study the correlation between three different lens nuclear opacity classification methods and intraoperative phacoemulsification parameters .

Full description

Slit-lamp lens images, Pentacam and IOL-Master 700 images were collected in patients with dilated pupil before cataract surgery, and phacoemulsification parameters on the Centurion phacoemulsification machine (Alcon) screen were recorded. Spearman correlation analysis was used to analyze the correlation between lens nuclear density and phacoemulsification parameters based on SS-OCT and Scheimpflug techniques.

Enrollment: 53 estimated patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age-related cataracts performed by the same surgeon in our hospital;
2. Pupil diameter can be enlarged more than 6 millimetre.

Exclusion criteria

1. The pupil diameter cannot be dilated greater than 6mm;
2. previously ocular surgery or laser treatment;
3. history of ocular trauma;
4. other ocular diseases such as keratoconus, glaucoma and retinal detachment;
5. corneal opacities caused by leucoma, pterygium and other diseases;
6. lens dislocation or complicated cataract surgery (any complications during/after the operations);
7. poor fixation leading to low image quality or inability to cooperate with examinations.
