To evaluate the clinical outcome of vitrectomy in the management of dropped nucleus during phacoemulsification.
Twenty-five consecutive patients who underwent pars plana vitrectomy for the management of dropped nucleus from phacoemulsification, over a 36-month period, were studied. Twenty-two patients underwent vitrectomy within 15 days of cataract surgery. Most of the patients were followed for more than 6 months.
Final visual acuity was 20/40 or better in 71% (17/24) of eyes and 20/50 in 8% (2/24). Visual acuity was 20/70 or worse in 21% (5/24) of patients. Complications included persistent cystoid macular edema in three eyes, epimacular proliferation in two eyes, and a choroidal detachment in one eye.
Poor visual outcome after dropped nucleus at phacoemulsification cataract extraction can be avoided if managed by prompt pars plana vitrectomy.
评估玻璃体切除术在处理白内障超声乳化术中晶状体核坠入玻璃体腔的临床效果。
对连续25例在36个月期间因白内障超声乳化术中晶状体核坠入玻璃体腔而接受平部玻璃体切除术的患者进行研究。22例患者在白内障手术后15天内接受了玻璃体切除术。大多数患者随访时间超过6个月。
71%（17/24）的患眼最终视力达到20/40或更好，8%（2/24）的患眼视力为20/50。21%（5/24）的患者视力为20/70或更差。并发症包括3只眼持续性黄斑囊样水肿，2只眼黄斑前增殖，1只眼脉络膜脱离。
如果通过及时的平部玻璃体切除术进行处理，白内障超声乳化术中晶状体核坠入玻璃体腔后可避免视力不佳的结局。
