Posterior capsular clarity is important for long-term visual gain. Postoperative visual acuity could be reduced due to posterior capsular or intraocular lens opacification, which occur months or years after cataract surgery. We report early occurrence of posterior capsular calcification without opacification of intraocular lens.
We report the case of a 78-year-old male who had undergone phacoemulsification with implantation of hydrophilic intraocular lens (IOL) in the left eye for cataract. The patient was non-diabetic, and the surgical procedure was uneventful. On the third postoperative day, fine granular deposits were found on the mid-peripheral part of the posterior capsule. No deposits were found on IOL. The patient presented with diminished vision four months after surgery. Slit-lamp examination revealed distinct areas of calcification with an early opacification of the posterior capsule and no IOL calcification. Neodymium doped: YAG capsulotomy was done to clear posterior capsular opacification, and the patient regained visual acuity of 20/20. To the best of our knowledge, this report is the first to investigate posterior capsular calcification without opacification of IOL in a patient without any known etiological factors.
This case is reported to stimulate future study on the use of BSS plus and the development of posterior capsular or IOL calcification.
后囊膜清晰度对于长期视力恢复很重要。白内障手术后数月或数年,后囊膜或人工晶状体混浊可能导致术后视力下降。我们报告了一例早期发生后囊膜钙化但人工晶状体未混浊的病例。
我们报告了一名78岁男性患者,其左眼因白内障接受了超声乳化白内障吸除术并植入了亲水人工晶状体。该患者无糖尿病,手术过程顺利。术后第三天,在后囊膜的中周边部分发现了细小的颗粒状沉积物。人工晶状体上未发现沉积物。患者术后四个月视力下降。裂隙灯检查显示后囊膜有明显的钙化区域,并伴有早期混浊,人工晶状体未钙化。进行了掺钕钇铝石榴石激光后囊膜切开术以清除后囊膜混浊,患者视力恢复到20/20。据我们所知,本报告是首例在无任何已知病因的患者中研究人工晶状体未混浊的后囊膜钙化的病例。
报告该病例是为了激发未来对平衡盐溶液加药以及后囊膜或人工晶状体钙化发展的研究。
