To evaluate the potential of diode laser thermokeratoplasty (DTK) in the correction of irregular astigmatism in patients with keratoconus.
The coagulation of deep layers of cornea stroma was made on four eyes of four patients suffering from advanced keratoconus at the mean age of 31 years by means of the infrared contact cw laser Prolaser Rodenstock 1.9 DTK. The aim of the treatment was to increase the curvature of cornea in flat meridians and to compensate flattening of cornea in steep meridians by way of forming traction strips between the contracted tissue of individual coagulation points. The changes on the cornea topography and changes of visual functions were determined.
The diode laser keratoplasty is capable to induce sector increase of cornea curvature and thereby improve symmetry pictures of irregular astigmatism in keratoconus. For a definitive inclusion of DLK into the spectrum of clinically applicable procedures, other therapeutic studies are needed as well as larger groups with relatively homogeneous pre-operation pictures.
评估二极管激光热角膜成形术(DTK)矫正圆锥角膜患者不规则散光的潜力。
使用红外接触式连续波激光罗敦司得1.9 DTK,对4例平均年龄31岁的晚期圆锥角膜患者的4只眼睛进行角膜基质深层凝固。治疗目的是通过在各个凝固点的收缩组织之间形成牵引带,增加角膜扁平子午线的曲率,并补偿角膜陡峭子午线的扁平化。测定角膜地形图的变化和视觉功能的变化。
二极管激光角膜成形术能够诱导角膜曲率扇形增加,从而改善圆锥角膜不规则散光的对称图像。为了将DLK最终纳入临床适用程序的范围,还需要其他治疗研究以及术前图像相对均匀的更大样本组。
