Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Not-attended rate | Compare the SMS and free eye drops patient not-attend rate with the control group to show the impact of SMS reminder associated with free eye drops on the adherence with scheduled follow-up visit | up to 1 year |
