摘　　要：目的:设计用准分子激光对表面角膜镜片进行加工时所用的模座。方法:通过理论分析建立了所设计的模座的曲率半径和待加工角膜镜片屈光度之间关系的方程式。根据计算结果试制成模座。结果:采用动物角膜进行了试验性加工,所设计的模座可加工出具有预期屈光度的角膜镜片。结论:设计的12D模座能加工出适宜于角膜表面镜片术应用的且有合适屈光度的角膜镜片。眼科学报 1995;11:180—182。Purpose: To design a mold for processing optical power in epikeratophakia. Method: With excimer laser, a corneal graft with appropriate optical power shall be got on the formula of the mold's radius curvature. Results: Based upon the formula from the data, a 12D mold was accomplished to obtain a suitable cornea lens for epikeratophakia. Conclusion: The 12D mold presents the value to some extent in processing the desired optical power of corneal graft for those patients requiring epikeratophakia. Eye Science 1995; 11: 180-182.
