Description

technical field [0001] The invention relates to the technical field of computing systems after corneal refractive surgery, in particular to an IOL FY-L computing system after corneal refractive surgery. Background technique [0002] Corneal refractive surgery is a method of correcting nearsightedness, hyperopia, and astigmatism. According to international standards, according to the site of surgery, it can be divided into 13 types in three categories: corneal surgery, lens surgery and scleral surgery. [0003] Usually, various inspections and nursing care are required after the operation to ensure the success of the operation. Therefore, IOL calculation is required. There are many factors affecting the IOL calculation after corneal refractive surgery, and there are many numerical information to be calculated and measured, which is also relatively important. Existing A variety of independent measuring instruments are required for postoperative measurement and calculation. Th...

Problems solved by technology

[0003] Usually, various inspections and nursing care are required after the operation to ensure the success of the operation. Therefore, IOL calculation is required. There are many factors affecting the IOL calculation after corneal refractive surgery, and there are many numerical information to be calculated and measured, which is also relatively important. Existing A variety of independent measuring instruments are required for postoperative measurement and calculation. The integration of the measurement and calculation instruments is low, and it is more troublesome. For corneas that have undergone excimer myopia refractive surgery, keratometer or corneal topography The corneal curvature measured by the graph is not accurate enough. If the calculated corneal curvature is greater than the actual value, then after implanting the corresponding intraocular lens, the patient will have different degrees of postoperative hyperopia. Therefore, the accuracy of the calculation after corneal refractive surgery is particularly important.
