Bilateral clear lens extraction and intraocular lens implantation in a child with microspherophakia and Marfan syndrome

ABSTRACT We report the case of a 4-year-old boy with Marfan syndrome whose parents reported he had had low visual acuity since birth. On examination, there was microspherophakia and a small subluxation of the lens. The objective refraction was -23.75 - 2.75 x 70 in the right eye and -25.50 -3.50 x 90 in the left eye. Since the microspherophakia and the high myopia severely affected the boy's quality of life, clear lens extraction, anterior vitrectomy, posterior surgical capsulotomy via the pars plana, and intraocular lens implantation were performed. Two years postoperatively, the patient had centered intraocular lenses and a corrected visual acuity of 20/30 in both eyes. The child was satisfied with his vision and was able to study and perform daily activities without visual limitations.

摘要 本文报告1例4岁马方综合征（Marfan Syndrome）男性患儿，其家长自述患儿自出生起即存在视力低下。眼科检查显示患儿存在小球形晶状体（microspherophakia）及晶状体轻度半脱位。右眼客观验光结果为-23.75 -2.75 ×70，左眼为-25.50 -3.50 ×90。鉴于小球形晶状体与高度近视严重影响患儿生活质量，临床遂行晶状体摘除术、前段玻璃体切割术、经睫状体平坦部后囊膜切开术及人工晶状体植入术。术后2年随访，患儿人工晶状体位置居中，双眼矫正视力均为20/30。该患儿对自身视力状况满意，可正常开展学习及日常活动，无视觉相关活动受限。
