目的：分析眼球穿通伤所致白内障ＩＯＬ植入术后继发性近视发生的情况．方法：观察４ 例眼球穿通伤所致白内障ＩＯＬ 植入术后发生继发性近视的原发性损伤、治疗经过、继发性近视的发生／发展及矫正结果．结果：受伤年龄１１岁～３１岁，受伤前均系正视眼，白内障摘除及ＩＯＬ 植入术都在受伤后２月内施行，ＩＯＬ屈光度合适，继发性近视的形成／发展于术后３月以上甚至３年或者更长的时问．结论：眼球穿通伤所致白内障ＩＯＬ 植入术后继发性近视的发生可能与眼穿通伤造成伤眼角膜散先、角膜疤痕、晶体混浊、玻璃体混浊等多种形觉剥夺因素有关．强调对眼外伤尤其严重性眼外伤者长期随访的重要性，及时去除各种形觉剥夺因素，以恢复和保持伤眼的有用视力．
Objective: To analyze the incidence of secondary myopia after cataract IOL implantation caused by penetrating eyeball. Methods: The primary injury of myopia following cataract IOL implantation in 4 cases of penetrating traumatic eyeball was observed, and the incidence and development of secondary myopia and the results of correction were observed. Results: The age of injury ranged from 11 to 31 years old. All the patients were eyedrops before injury. Cataract extraction and IOL implantation were performed within 2 months after injury. The IOL refraction was correct. The formation and development of secondary myopia were observed in March More than three years or more when asked. Conclusion: The incidence of secondary myopia after cataract IOL implantation caused by penetrating traumatic eye injury may be related to the various forms of deprivation of traumatic corneal sclerosis, corneal scarring, crystal opacity and vitreous opacity. Emphasize the importance of long-term follow-up of ocular trauma especially for ocular trauma and timely removal of various forms of deprivation to restore and maintain the useful visual acuity of the injured eye.
