METHOD FOR CARRYING OUT LASIC-OPERATION WITH PRELIMINARILY FORMED PRIMARY INCOMPLETE CORNEAL VALVE Russian patent published in 2007 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: method involves marking symmetry axis of primary incomplete or broken corneal valve for determining its pedicle position. Repeated corneal valve on pedicle is formed with its thickness being greater than that of the primary corneal valve. When forming the repeated corneal valve on pedicle having diameter greater than the primary incomplete or broken corneal valve diameter, symmetry axis of the repeated incomplete or broken corneal valve is traced at an angle of 80-100° to the primary corneal valve symmetry axis. When forming the repeated corneal valve on pedicle having diameter equal to the primary incomplete or broken corneal valve diameter, the repeated corneal valve symmetry center is 0.5-1 mm far along the primary valve symmetry axis from its center towards the beginning of repeated corneal valve formation. The repeated corneal valve symmetry axis is traced through this center at an angle of 80-100° to the primary incomplete corneal valve symmetry axis. Laser ablation of stromal corneal bed after having formed the repeated corneal valve on pedicle with microkeratome.

EFFECT: enhanced effectiveness of treatment.
