About this trial
To analyze the difference between measured total corneal astigmatism and actual corneal astigmatism under different region modes and optimize the region setting.
Eligibility criteria
Qualifiers
Age ≥ 18 years
Patients who had received phacoemulsification surgery with or without implantation of toric IOL are with a certain amount of corneal astigmatism.
Best corrected visual acuity ≥ 0.66 (20/30 Snellen)
Disqualifiers
Corneal diseases or severe irregular astigmatism (e.g., pterygium, keratoconus), existence of corneal opacification;
Ocular disease which may affect visual acuity (e.g., glaucoma, uveitis, retinal disease, pathologic myopia);
History of ocular surgery or ocular trauma before this cataract surgery;
Decentration of IOL > 0.3mm or tilt > 5°
