Abstract Details



Purpose:

To evaluate liquid hydrogel ocular bandages (OcuSeal&trade and ReSure&trade) to cover and protect clear corneal cataract surgical incisions.

Setting:

C.M.A Centro di Microchirurgia Ambulatoriale, Via Donizetti 24, Monza (Milan)

Methods:

At the conclusion of cataract surgery, we applied OcuSeal&trade liquid bandage (Beaver Visitec International) in 301 eyes of 219 patients (mean age67.69 ± 11.91) or ReSure&trade Adherent Ocular Bandage (Ocular Therapeutix Massachusetts,USA) in 74 eyes of 65 patients (mean age 68.11 ± 9.89) to reinforce closure of clear corneal incisions (up to3.75mm).OcuSeal&trade consists of a synthetic dentritic hydrogel comprised of2separate components: powdered polyethylene glycol (PEG) and liquid polyethylene amine(PEI). Resure&trade consists of a polyethylene glycol-based hydrogel. Hydrogel is activated by mixing 2 separate components: powder polyethylene glycol(PEG)and a diluent liquid precursor containing trilysine. After application, both bandages cross-link within 30 seconds.

Results:

During the immediate post-operative interval, patients treated with both bandage reported improved comfort. Resure&trade protected the wound by remaining localized over the de-epithelialized tissue for at least 24 hours in 74 eyes (100%) of patients while Ocuseal&trade within 12 hours.

Conclusions:

Liquid bandage applied at completion of cataract surgery may enhance incisional wound closure and improves post-operative patient comfort. After refilling with BSS, the anterior chamber is increasing with the bandages due to improvement of watertight properties.
