Pre-cut donor tissue for Descemet stripping automated keratoplasty: anterior hinged lamella on versus off.

Aims: To compare two different techniques for preparation of pre-cut lamellar corneal tissue for Descemet stripping automated keratoplasty.

Background/methods: Eight donor lenticules were created with a full pass of the microkeratome blade, which resulted in a posterior lamella and a free cap (anterior lamella off group (AL-off)). Contralateral donor lenticules were created with an incomplete pass of the microkeratome blade, which resulted in a posterior lamella and a hinged anterior cap (anterior lamella on group (AL-on)).
