High voltage electric burns can cause various ocular injuries and may manifest in the form of conjunctival hyperemia, corneal opacities, uveitis, miosis, spasm of accommodation, cataract, retinal edema, papilledema, choroidal rupture, chorio-retinal necrosis/atrophy, retinal detachment and optic atrophy. The involvement of crystalline lens exclusively with sparing of other ocular structures is rare. We report a case of 16 year old male with bilateral total cataract after electrical injury by over-head high tension electric transmission cable accidentally falling on patient's head 6 months back. B scan showed no abnormality in both the eyes. The intra ocular pressure in both the eyes was within normal limits. Patient underwent lens aspiration with posterior chamber intraocular lens (PCIOL) implantation in both the eyes, under peribulbar anaesthesia (with an interval of 1 week between both the operations). Intra-operative and post-operative period were uneventful. Post operative BCVA was 6/6 in both eyes and fundus examination was within normal limits. Outcomes after surgery are very good if not associated with other ocular lesion like optic atrophy, chorio-retinal lesion, uveitis etc. This observation should encourage the ophthalmologist to undertake surgery for electric cataract, where necessary.
高压电烧伤可导致各种眼部损伤，表现形式可能有结膜充血、角膜混浊、葡萄膜炎、瞳孔缩小、调节痉挛、白内障、视网膜水肿、视乳头水肿、脉络膜破裂、脉络膜视网膜坏死/萎缩、视网膜脱离及视神经萎缩。单纯晶状体受累而其他眼部结构未受累的情况较为罕见。我们报告一例16岁男性患者，6个月前 overhead 高压输电电缆意外落在其头部，导致电击伤后双侧完全性白内障。B超显示双眼无异常。双眼眼压均在正常范围内。患者在球周麻醉下双眼行晶状体抽吸联合后房型人工晶状体（PCIOL）植入术（两次手术间隔1周）。术中和术后过程顺利。术后双眼最佳矫正视力（BCVA）均为6/6，眼底检查正常。如果不伴有视神经萎缩、脉络膜视网膜病变、葡萄膜炎等其他眼部病变，手术效果非常好。这一观察结果应鼓励眼科医生在必要时对电伤性白内障进行手术。
