中文摘要 | 目的:報告一位高度近視病患發生自發性水晶體脫位的病例。方法:病例報告。結果:一個47歲女性在早上洗完臉之後發現右眼視力突然模糊來我們眼科門診求診。她有高度近視及白內障的病史並於九年前接受了雙眼白內障晶體乳化合併人工水晶體(MZ30BD, Alcon, length: 12.0mm, optic: 5.5mm)置入手術,並在六年前接受右眼雷射去後囊增生術。求診當時右眼最住矯正視力為5/60,左眼最佳矯正視力為6/6。裂隙燈下鏡檢發現右眼人工水晶體脫位及前玻璃體自後囊造口處往前突。於是為其施行人工水晶體移除並放置較大的人工水晶體(MC50BD, Alcon, length: 13.5mm, optic: 6.5mm)。病患在三個月後的術後追蹤右眼的最佳矯正視力為6/6.7,而兩年後的最佳矯正視力為6/7.5。結論:造成此病例手術後人工水晶體脫位的可能因素包括有長眼軸,雷射去後囊增生術術後及小人工水晶體。在有高度近視的病人因有較大的眼球體積及較寬的水晶體後囊,較小的人工水晶體可能會產生自發性脫位,尤其是在雷射去後囊增生術後。 |
英文摘要 | Purpose: To report a case of high myopia with spontaneous intraocular lens (IOL) dislocation. Methods: Case report. Results: A 47-year-old women came to our out-patient clinic due to sudden loss of vision of her right eye after washing her face in the morning. She was a victim of high myopia (OU) and had received cataract surgery (OU). Nine years ago she underwent phacoemulsification of her cataract with IOL (MZ30BD, Alcon, length: 12.0mm, optic: 5.5mm) implantation (OU) and laser capsulotomy (OD) 6 years ago. Under slit-lamp microscope, IOL dislocation and anterior vitreous protrusion through the capsulotomy site were noted. IOL exchange with a new IOL of a bigger size (MC50BD, Alcon, length: 13.5mm, optic: 6.5mm) was then performed. Best corrected visual acuity was 6/6.7 (OD) 3 months and 6/7.5 (OD) 2 years later. Conclusions: Possible predisposing factors for IOL malposition following surgery include a long axis of the eye ball and capsulotomy, especially when a small-sized IOL was implanted, as in the present patient. |
