Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Demodex blepharitis is a prevalent cause of comorbid infection among individuals undergoing cataract surgery. Several complications may arise in the postsurgical period from Staphylococcus or Streptococcus co-infections, as Demodex is a vector for these pathogens. Hence, prophylactic treatments before cataract surgery may lead to a reduction in complication rates. Since Demodex infestation and cataract surgery are two prevalent coexisting conditions in the general population, this study aims to test the effect of four combined treatments to eradicate or improve the Demodex infestation index before surgery. The investigators are conducting a single-blinded randomized trial of four therapies in participants undergoing cataract surgery. All participants will or are receiving daily eyelid cleansing bid and topical 0.3% ciprofloxacin q4h for three days added to the allocated treatment arm. Our four intervention groups are: \[1\] Blephaclean eye scrubs; \[2\] 50% dilution baby shampoo; \[3\] tea tree oil shampoo; \[4\]: topical 0.3% ciprofloxacin alone. To assess treatment efficacy, the investigators will perform eyelash hair epilation pre and postoperatively. The primary outcome is a change in the mean Demodex spp. infestation index. Also, a change in the crude number of Demodex (egg, larvae, nymph, or adult-form) spp. in eyelashes after one-week of therapy.

Demodex Infestation Demodicosis Cataract

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients diagnosed with Demodex spp. infestation undergoing cataract surgery were randomly allocated into four comparison groups a control group (standard treatment) and three new modalities of Demodex therapy (Blephaclean, baby shampoo, and tea tree oil) + conventional treatment.
Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Investigators Outcome Assessors
Investigators and outcomes assessors were blinded to the treatment allocation of each participant. Outcome assessors were anterior segment surgeons who evaluated cases prior to cataract surgery. There was no indication of group allocation in the electronic medical records (EMR), only the participation of each candidate in the study. Similarly, investigators were blinded to group allocation and only recorded data directly from EMR. Blinding was kept after data analysis.
