糖尿病白内障国产折叠人工晶状体植入术的临床观察

A clinical observation on the implantation of domestically made foldable intraocular lens in diabetic cataract patients

目的观察国产折叠式疏水性丙烯酸酯人工晶状体（DF—IOL）植入糖尿病白内障患者的安全性及有效性。方法对82例（125眼）糖尿病白内障行晶状体超声乳化吸出联合DF—IOL植入术，术后观察视力、角膜水肿、前房反应、眼压、后发性白内障等情况。结果9眼瞳孔散大不理想，有1眼后囊抛光时后囊破1小孔，所有病例囊袋顺利植入DF—IOL，术中无前房积血或悬韧带断裂，术后1d视力〈0．3者10眼（8．00％）、≥0．3者115眼（92．00％）、≥0．5者89眼（71．20％）、≥0．8者23眼（18．40％）；术后1d角膜水肿34眼（27．20％），1周内均消退，未发现角膜后沉着物、高眼压、虹膜粘连或晶状体表面渗出膜，无眼内炎发生，后发性白内障发生率仅8．80％。结论糖尿病白内障DF—IOL植入术是安全的、有效的。

Objective To observe the safety and effect of implanting domestically made hydrophobic acrylic foldable IOL（DF-IOL） for the patients with diabetic cataract. Methods One hundred and twenty five eyes of 82 cases of diabetic cataract were operated with phacoemulsification and DF-IOL implantation. The visual acuity, corneal edema, anterior chamber inflammation, intraocular pressure （IOP） and posterior capsule opacification （PCO） after the surgery were observed. Results The pupillary dilation was not ideal in 9 eyes and the posterior capsular rupture（PCR） with a tiny hole when polishing occurred in 1 eye. The DF-IOL was implanted into the capsular bag in all cases without intraoperative hyphema or zonular dialysis. One day after the suegery,the visual acuity was less than 0.3 in 10 eyes（8.00% ）, better than 0.3 in 115 eyes （92.00%）, better than 0.5 in 89 eyes （71.20%） and better than 0.8 in 23 eyes （ 18.40% ）. Thirty -four eyes （27. 20% ） had corneal edema which faded away within 1 week. No keratic precipitate, intraocular hypertension, synechia, IOL surface exudate or endophthalmitis occurred. The incidence rate of PCO was only 8.80% . Conclusion DF-IOL implantation is safe and effective for diabetic cataract.
