Aims: To establish a keratoprosthesis (Kpro) surgical technique that maintains an intact superficial corneal layer. Methods: A manual microkeratome (Moria LSK-1) was used to create a 130 mm flap of approximately 10 mm diameter in the right eye of Japanese white rabbits. The stoma beneath the flap area was dissected before the removal of a 5.0 mm stromal disc. A 5.0 mm collagen I immobilised pol...

OBJECTIVE To develop a laboratory model to study intracorneal keratoprosthesis implantation. METHODS A combination microkeratome and artificial anterior chamber system was used to create a hinged lamellar keratectomy on 13 human corneas. After reflecting the flap, the posterior stroma was trephined at either 2.5 or 3.0 mm. A model keratoprosthesis was positioned in the bed. The flap was sutur...

PURPOSE To describe the effect of prolonging the standard suction duration during laser-assisted in-situ keratomileusis (LASIK) and its effect on flap thickness and hinge length using sub-Bowman keratomileusis (SBK) microkeratome. METHODS Fifty-six eyes (28 patients) were included and divided into 2 groups; Group-A: eyes with flatter corneas (36 eyes, 18 patients) and mean keratometric readin...

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 p...

PURPOSE To determine the incidence and the type of flap complications in our initial series of eyes undergoing laser in situ keratomileusis and the impact of microkeratome-related complications on best spectacle-corrected visual acuity. METHODS We reviewed the charts of the 630 consecutive eyes operated in the Refractive Surgery Department of Cerrahpasa Medical School, University of Istanbul,...

PURPOSE To evaluate flap dimensions and cut deterioration with repeated blade use in an automated microkeratome. METHODS The Automated Corneal Shaper (Chiron-Adatomed, Munich, Germany), 160-microm plate attached, was used to make a corneal flap in 90 pig cadaver eyes, reusing blades up to five times. Flap diameter was measured by planimetry and thickness was calculated by ultrasound pachymetr...
