目的 :对角膜塑型术 (Orghokeratology,OK镜 )治疗中患者出现的重影现象进行初步分析。方法 :观察随访 9～ 14月的 OK镜治疗者共 5 0例 96眼的重影情况 ,并重点分析重影出现与近视度数、偏位情况、角膜上皮情况等的关系。结果 :本组≤ - 3.0 DS,- 3.2 5～ - 5 .0 DS,>- 5 .0 DS三组患者重影发生率分别为 2 9.6 %、 6 3.8%和 81.8% ,且伴散光者 6 0 %有重影 ,说明随着近视度数的加深 ,重影产生的比率越高 ,且以伴散光者为多 ,重影与角膜上皮擦伤关系不密切 ,但与中央的擦伤有关。重影的产生与次弧下荧光环的形态及镜片偏位有密切关系 ,这关键是我们操作医生未能参与设计或与设计者根本无法沟通 ,不能随个体差异的不同及时进行调整的原因。结论 :OK镜虽可提高远视力 ,但治疗过程中所存在的视觉质量问题 ,值得关注。
Objective: To analyze the ghosting phenomenon in patients with Orghokeratology (OK) treatment. Methods: A total of 50 patients (96 eyes) with OK mirror who were followed up from 9 to 14 months were observed. The relationship between the appearance of ghosting and the degree of myopia, deviation and corneal epithelium were analyzed. Results: The incidence of ghosting in the patients with ≤3.0 DS, -3.25 ~ -5.0 DS,> -5.0 DS were2.66%, 68.8% and81.8%, respectively, and those with astigmatism6 0% ghosting, indicating that with the deepening of myopia, ghosting the higher the rate, and astigmatism and more, ghosting and corneal epithelial abrasions are not closely related, but with the central bruising. The occurrence of ghosting is closely related to the shape of the fluorescent ring under the secondary arc and the deviation of the lens. This is the reason that doctors in our operation can not participate in the design or can not communicate with the designer at all, and can not adjust in time according to individual differences. Conclusion: Although OK lens can improve the far vision, but the visual quality problems in the course of treatment is worth attention.
