This systematic review and meta-analysis evaluated the efficacy and safety of intense pulsed light (IPL) therapy for managing dry eye syndrome after LASIK surgery. Analyzing four studies with 146 treated eyes, the results indicated a significant improvement in patient-reported symptoms as measured by the Ocular Surface Disease Index (OSDI) with a P-value of 0.005, although other clinical outcomes did not achieve statistical significance.
Key findings
- IPL therapy significantly improved OSDI scores with a P-value of 0.005.
- Improvements in tear breakup time, artificial tear use, corneal staining, lipid layer thickness, and meibomian gland function were noted but not statistically significant.
- Substantial heterogeneity was observed between studies.
- Follow-up duration across studies was limited, ranging from 0 to 24 weeks.
Why it matters
Understanding the potential benefits of IPL therapy for post-LASIK dry eye is crucial for clinicians managing patients with this common complication. Improved symptom management could enhance patient quality of life.
What to keep in mind
The evidence is limited due to the small number of studies and the short follow-up duration.
