made at both sides of the main incision and at the inferior limbus. A drainage incision was made from the limbus at the 4 o'clock position. Irrigation was placed in the anterior chamber. Peripheral iridectomy was routinely performed to prevent pupillary block. The position of the iridectomy was dependent on each patient's specific conditions.

Preparation of Donor Tissue {#s2e}
---------------------------

The donor tissue was prepared by the Moria automated lamellar therapeutic keratoplasty microkeratome equipped with a 300 micron head and associated artificial AC (Moria Inc. Doylestown, PA, US). Following the microkeratome pass, the anterior stromal "cap" was removed, and the donor button mounted on the artificial AC was brought under view of the operating microscope. The graft diameter size was dependent on each patient's specific requirements, and ranged from 7 mmo'clock position. The Healon GV in the anterior chamber was removed with a balanced saline solution (BSS, Alcon, Fort Worth, TX, USA). The Busin glide was brought to the main limbal incision at the 12 o'clock position. Using a small amount of irrigation and pulling the stitch, the donor lenticule disc was inserted into the anterior chamber. The main incision was sutured. Irrigation was increased and the donor lenticule was unfolded. The anterior chamber was sufficiently deep and well maintained. The position of the donor lenticule was adjusted to attach to the matching area of the Descement membrane stripping and the anchoring prolene stitch was cut. No instrument entered the anterior chamber during the insertion procedure. A lenticule-sized bubble was injected from the auxilliary incision. Removal of fluid
