About this trial

The goal of this clinical trial is to learn if nomogram could promote treatment outcomes in astigmatism correction. The main question it aims to answer is:

does the nomogram could promote treatment outcomes in astigmatism correction? If there is a comparison group: Researchers will compare non-nomogram adopted to see if the outcome acceptable.

Participants will ask to complete 3-month follow-up of manifest refraction and visual acuity test.
