To report the explanation and exchange of Hydrophilic Acrylic foldable intraocular lens (IOL) on 14 patients who had visual disturbances caused by the change of transparence on optic.
Sixteen Hydrophilic Acrylic foldable intraocular lenses from 14 patients who presented with decreased visual acuity from 6 months to 1 year after normal phacoemulsification and IOL implantation associated with extensive transparent change on optic of the lens. The lenses were explanted with the bisection technique. All the eyes were reinserted with Acrysof foldable lenses.
Sixteen lenses were removed successfully and exchanged with the new lens in the capsule. The posterior capsular rupture and vitreous loss were found in the first two cases. One of them had the zonulysis due to the radial tear of the anterior capsule during the enlargement of the capsular opening. The anterior vitrectomy was performed with IOL fixed on the ciliary sulcus. The visual acuity of all the patients improved obviously without posterior complication.
Foldable lens explanation with the bisection technique and exchange had a successful outcome with improvement of ocular condition.
报告对14例因人工晶状体光学部透明度改变导致视力障碍的患者进行亲水性丙烯酸折叠式人工晶状体（IOL）的取出及置换情况。
14例患者在正常白内障超声乳化吸除联合IOL植入术后6个月至1年出现视力下降，晶状体光学部出现广泛透明性改变，共取出16枚亲水性丙烯酸折叠式IOL。采用二分法取出晶状体。所有患眼均重新植入Acrysof折叠式人工晶状体。
成功取出16枚晶状体并在囊袋内置换新晶状体。前两例发生后囊膜破裂及玻璃体脱出。其中1例在扩大囊口时前囊膜发生放射状撕裂导致悬韧带离断。行前部玻璃体切除术并将IOL固定于睫状沟。所有患者视力均明显提高，无术后并发症。
采用二分法取出并置换折叠式人工晶状体取得成功，眼部情况得到改善。
