Condition(s) studied
Astigmatism
Investigational drug(s) / intervention(s)
nomogram
nomogram: nomogram was added to nomogram group
Study summary
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.
