Systane lubricant eye ointment should be used for 1-4 weeks after an ocular procedure, depending on the individual's healing progress and the doctor's specific instructions. The duration of use can vary based on the type of procedure and the patient's response to the treatment.
- Apply a small ribbon (about 1/4 inch) of ointment inside the lower eyelid 2-4 times daily and at bedtime.
- The ointment forms a protective barrier over the eye's surface, providing longer-lasting lubrication than eye drops, which helps promote healing and reduces discomfort after procedures.
- It's normal for the ointment to cause temporary blurred vision, so it's best applied before sleep or when clear vision isn't needed.
- If you experience increased pain, redness, discharge, or vision changes while using the ointment, contact your eye doctor immediately as these could indicate complications.
- Always wash your hands before application and avoid touching the tip of the tube to prevent contamination. According to a study published in 2020 1, Systane lubricant eye drops provided instant and sustained symptom relief for 8 hours post-single application, which supports the use of Systane ointment for an extended period. Another study from 2009 2 showed that Systane lubricant eye drops improved ocular surface parameters in subjects with moderate symptoms of ocular dryness after 28 days of use, further supporting the extended use of Systane ointment. However, the specific duration of use should be determined by the eye doctor based on individual patient needs and response to treatment.
