Low-Level Light Therapy Improves dry eye symptoms among patients undergoing Cataract Surgery
Cataract Surgery
Optimizing the ocular surface prior to cataract surgery has been highlighted in recent studies, especially for individuals who already have dry eye disease (DED). Nevertheless, a recent study published in British Journal of Ophthalmology indicates that even healthy patients having cataract surgery may benefit from low-level light therapy (LLLT) as a prophylactic measure.
Researchers have found in a new study that two sessions of low-level light therapy before and after cataract surgery were effective in ameliorating tear film stability and ocular discomfort symptoms.
LLLT or a sham therapy was randomly assigned to 153 individuals in this double-masked research. The sessions took place both before and after cataract surgery. The Ocular Surface Disease Index (OSDI) questionnaire, non-invasive break-up time (NIBUT), tear meniscus height, meibomian gland loss (MGL), and redness score were among the outcomes measured by the trial thirty days after surgery.
Patients who received LLLT demonstrated significantly lower OSDI scores at two different postoperative time points, indicating reduced ocular discomfort compared to the control group. Additionally, NIBUT values were higher among the LLLT-treated patients at the second assessment, suggesting improved tear film stability. Meibomian gland loss, which is often associated with DED, was also lower in the LLLT group at the first postoperative assessment.
