About this study
This study is to compare the clinical outcome of Precizon toric intraocular lens(IOL) to that of Tecnis toric IOL.
Read the detailed description
In cataract surgery, after phacoemulsification, intraocular lens should be implanted for patient's better visual acuity. When patient has large amount of corneal astigmatism, toric intraocular lens are recommended to correct the preexisting astigmatism.
- Conditions
- Astigmatism
- Being tested
- Precizon toric intraocular lens, Tecnis toric intraocular lens

Questions about this trial
What is this clinical trial studying?
A study testing Precizon toric intraocular lens and Tecnis toric intraocular lens in people with Astigmatism, run by Samsung Medical Center.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative refractive astigmatism (time frame: postoperative 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03085901, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
