摘要

我們回溯性分析，有關玻璃體切除術後產生白內障，而接受晶體乳化術病患之病歷，探討其視力預後，手術中及手術後的併發症。本研究共收集35個病人，36隻眼睛。最終手術後視力，改善者有35隻眼睛，佔97%，維持不變有1隻眼睛，佔3%，有少數病人手術中產生前房深淺變動大，瞳孔縮小，造成手術困難，有一位病人在手術中產生後囊破裂，晶核掉入玻璃體中，這個病人，手術前已懷疑有後囊破裂，這可能是玻璃體切除術時產生的。手術後最常見的併發症是續發性白內障。我們的結論是：晶體乳化術在這類白內障是很安全的，手術中及手術後的併發症並不常見。雖然原先視網膜的狀況限制了視力的進步，但大多數的病人，術後的視力都得到改善。

We performed a retrospective study to review the charts of patients with a history of vitrectomy and subsequent phacoemulsification to assess the visual outcome, intraoperative and postoperative complications. Thirty-six eyes of 35 patients were studied. The best-corrected visual acuity improved in 35(97%) of 36 eyes and unchanged in 1(3%) of 36 eyes. In a few cases, surgery was made difficult by unusual fluctuation in anterior chamber depth and small pupil size. Intraoperative complication occurred in one eye with posterior capsule rupture and lens drop into the vitreous, which was probably caused by lens touch during previous vitrectomy. The most common late complication was after cataract. In conclusion, phacoemulsification and IOL implantation can be performed safely in postvitrectomy eyes. Intraoperative and postoperative complications were uncommon. Preexisting posterior segment lesions limited the ultimate improvement in visual acuity, hut visual acuity of most patients had improved postoperatively.
