We describe the technique and the results of three cases where we performed a posterior lamellar keratoplasty.
Case reports
The following surgical technique was performed in all cases. The donor posterior button was obtained from an entire fresh globe. We made sure that intraocular pressure was adequate by injecting BSS (balanced salt solution, Alcon) in the vitreous cavity. With a Moria ONE microkeratome, an anterior cap of 250 μm was cut and lifted. A Barron trephine 7 mm in diameter was used to obtain the posterior button, covered afterwards with viscoelastic to protect it and to avoid desiccation.
With our microkeratome an 8.5 mm in diameter, nasal hinge and 250 μm flap was obtained. The trephination was made with a 7 mm Barron trephine and completed with corneal scissors, under viscoelastic protection.
After the intraocular injection of acetylcholine the posterior donor button was placed on the recipient eye under viscoelastic protection. Six 10-0 Nylon interrupted sutures were used to secure and close the wound. Immediately after, the flap was put back and fixated with six interrupted 10-0 Nylon sutures and the knots were buried. The viscoelastic anterior chamber was exchanged with …
