The effect of punctal plugs in reducing ocular surface irritation after povidone-iodine preparation of intravitreal injection-a randomized trial.

ABSTRACT:

Purpose

To evaluate the utility of dissolvable collagen punctal plugs (CPP) in reducing ocular surface irritation after intravitreal injections (IVI).

Methods

Sixty-four subjects in the experimental group received CPP after intravitreal injections. Sixty-two controls did not receive CPP. Reductions in the Ocular Surface Disease Index^© (OSDI) and Standardized Patient Evaluation of Eye Dryness II (SPEED II) scores were analysed.

Results

Dry eye symptoms, as measured by reductions from the pre- to post-injection OSDI (p = 0.137) and SPEED II (p = 0.381) scores, did not significantly differ between the two groups. In sub-group analysis, patients with objective findings of dry eyes had significant improvement in their symptoms (p = 0.046) with CPP. The effect of
