The purpose of this prospective study is to evaluate the postoperative visual acuity, refractive error, intraocular pressure, and status of the posterior capsule in children with traumatic cataracts who undergo extracapsular cataract extraction and insertion of a posterior chamber lens.
Extracapsular cataract extraction and primary endocapsular fixation of a posterior chamber lens implant were performed in eight children (age range, 4-17 years) with unilateral traumatic cataracts.
There were no intraoperative complications, and seven of eight eyes achieved 20/40 or greater spectacle visual acuity during an average follow-up interval of 10 months (range, 5-20 months). The average postoperative spherical equivalent refractive error was +0.33 diopter (D) (range, -2.25 to +2.12 D); the average postoperative anisometropia was approximately 1 D (range, 0-2.25 D). In one patient, a coagulase-negative staphylococcal endophthalmitis developed 10 days after surgery. In three eyes that had opacified posterior capsules, YAG laser capsulotomy was performed.
These preliminary results suggest that intraocular lens (IOL) implantation may be a safe and effective method of optical correction for children with traumatic cataracts.
本前瞻性研究的目的是评估接受囊外白内障摘除及后房型人工晶状体植入术的外伤性白内障患儿的术后视力、屈光不正、眼压及后囊膜状况。
对8例(年龄范围4 - 17岁)单侧外伤性白内障患儿进行了囊外白内障摘除及后房型人工晶状体的一期囊内固定术。
术中无并发症发生,8只眼中有7只在平均10个月(范围5 - 20个月)的随访期内达到20/40或更好的矫正视力。术后平均等效球镜屈光不正为+0.33屈光度(D)(范围 - 2.25至+2.12 D);术后平均屈光参差约为1 D(范围0 - 2.25 D)。1例患者在术后10天发生了凝固酶阴性葡萄球菌性眼内炎。3只后囊膜混浊的眼睛进行了YAG激光囊膜切开术。
这些初步结果表明,人工晶状体植入术可能是外伤性白内障患儿进行光学矫正的一种安全有效的方法。
