Anterior Synechiolysis with Healon Needle and Ophthalmic Viscosurgical Devices after Anterior Lamellar Dissection in Penetrating Keratoplasty.

Purpose: We described a technique to perform anterior synechiolysis with a healon needle and Viscoat (R) ophthalmic viscosurgical devices (OVDs) through anterior lamellar dissection in penetrating keratoplasty. Methods: OVDs were gently injected between iridocorneal adhesions with a healon needle to make a blunt dissection after anterior lamellar corneal dissection. Anterior synechiolysis at 360 degrees was completed with a healon needle and OVDs. Subsequently, the deep corneal lamella was cut with right and left Troutman-Katzin corneal scissors. 24 interrupted sutures were made with 10-0 nylon suture to implant the donor cornea. Results: In two eyes from two patients, with corneal opacity and nearly total anterior synechiae, clear grafts and relatively deep anterior chambers were achieved. Penetrating keratoplasty with anterior synechiolysis was thus successful with a healon needle and OVDs through lamellar dissection. Conclusions: Anterior synechiolysis with a healon needle and OVDs through lamellar dissection is a safe and efficient technique for keratoplasty in patients with corneal opacity with anterior synechiae.
