目的 :对于软性角膜接触镜相关性表层点状角膜上皮病变 (SCL R SPK)进行临床分析 ,探讨防治措施。方法 :对于 2 0 2 8例SCL配戴者的验配记录进行回顾性研究 ,对于 1 68例SCL R SPK患者进行临床分析 ,探讨防治措施。结果 :SCL R -SPK发生率为 8 2 8%。位于睑裂部者占 80 95% ,发生率为 6 71 % ;弥漫型者占 1 5 4 8% ,发生率为 1 2 8%。 4 1 7%配适偏紧 ,但有 55 2 0 %所配SCL曲率半径偏小。 86 90 %无明显症状。复查过者占 70 2 4 % ,其中 3 6 90 %经处理后恢复配戴 ,3 1 55%未再复查 ,1 79%停戴。结论 :SCL R SPK颇为常见 ,其主要原因可能是由于泪膜稳定性下降 ,角膜干燥 ,其次是患者对护理液和 /或镜片沉淀物过敏。积极研发具有良好的保湿性能的SCL与作用强而温和的护理液 ;加强SCL护理教育 ,正确配戴 ,认真护理 ,如期更换镜片 ,定期复查 ,发现问题及时处理 ,可大大降低SCL R SPK发生率。除去诱因 ,SCL R SPK很容易愈合。
Objective: To investigate the clinical analysis of SCL R SPK associated with soft contact lens and to explore the prevention and treatment measures. Methods: A retrospective study was performed on the fitting record of 2 028 cases of SCL wearers. Clinical analysis was performed on 168 cases of SCL R SPK patients and the preventive measures were also discussed. Results: The incidence of SCL R-SPK was 82.8%. In the palpebral fissure accounted for 80 95%, the incidence was 6 71%; diffuse type accounted for 1548%, the incidence was 128%. 4 1 7% fit tight, but 55 2 0% with the SCL radius of curvature is small. 86 90% No obvious symptoms. 70,2 4% of the respondents were reviewed, of whom 36,90% recovered after treatment, 31 55% were not reviewed, and 1 79% stopped wearing them. CONCLUSIONS: SCL R SPK is quite common, primarily due to decreased tear film stability and corneal dryness, followed by patient allergies to conditioning fluids and / or lens deposits. Actively develop SCL with good moisturizing properties and strong and mild care solution; strengthen SCL nursing education, correct wear, serious care, regular replacement of lenses, regular review and timely treatment of problems, can greatly reduce the incidence of SCL R SPK . Remove the incentive, SCL R SPK is easy to heal.
