- Keratoconus or other irregular corneal patients
- Soft hydrophilic contact lens wearers are affected by long-term special conditions such as dryness, severe dust or volatile chemicals
- Pregnant, lactating or plan to be pregnant
- Only one eye meets the requirements for enrollment
- Participating in other clinical trials or less than ten days after the end of a soft contact lens clinical trial
- Less than three months after the end of a drug clinical trial

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
The ratio of corrected visual acuity of left and right eyes is ≥5.0
Time Frame: 1 week
|
The standard logarithmic visual acuity chart consistent with the guiding principle is adopted in this scheme. - Success criteria: If the lower limit of 95% CI of the evaluated rate of corrected for visual acuity for both eyes ≥ 5.0 at 1 week visit is ≥-10%, the primary endpoint of the two groups is non-inferior. |

The occurrence of adverse events
Time Frame: 3 month
|
Compare the number of adverse events and serious adverse events, the number of cases and the incidence rate; list the number and cases of adverse events; describe the adverse events that are related to the investigational products.
