摘要
目的评价三襻式Bi加ag人工晶状体在高度近视屈光晶状体置换术中的临床效果。方法对53例80只眼高度近视伴或不伴晶状体混浊，施行屈光晶状体置换术，其中单眼高度近视19例，双眼高度近视因近视力低于0．1，选择近视力及矫正视力较好的单眼进行手术的7例，双眼手术的27例，全部行超声乳化吸出植入低度数或负度数亲水性丙烯酸酯折叠Bigbag人工晶状体，观察术中和术后并发症。观察手术前后最佳远视力（VA），最佳矫正视力（BCVA），近视力（NVC），眼轴长度，屈光状态，术后随访6月-1年。结果术后56只眼（占70％）裸眼视力≥0．3，46只眼（占57．5％）裸眼视力I〉0．5，6只眼（占7．5％）裸眼视力i〉0．8，≤0．3有24只眼（占30％），除2例（占3．7％）术前裸跟近视力≤O．1，术后视力无改善外，其余病人均较术前最佳矫正视力提高。术中因撕囊口偏小，植人人工晶状体后囊破裂人工晶状体偏位1例，其余病例人工晶状体与后囊膜紧贴，后囊膜未见皱褶，人工晶状体固定良好。结论通过详细术前检查，超声乳化吸出植入低度数或负度数Bigbag人工晶状体，完成屈光晶状体置换手术安全有效，视觉质量好，不仅降低了后囊膜皱褶，后发性白内障，稳定囊袋，同时也减少了视网膜脱离的风险。
Objective To evaluate the clinical effects of folded artificial lens BigBag with three haptics in refractive lens exchange operation for highmyopia patients. Methods Eighty eyes of 53 patients with opaque lens or not were received the refractive lens exchange operation, 19 monocular high myopia patients, 27 binocular and 7 binocular who chose the eye with better near visual acuity or corrected visual acuity, accepted the phacoemolsification combined with hydrophilie folded acrylic intraocular lens （IOL） BigBag. Observed intra-operative and post operative complications, preopera- tive and post operative best visual acuity （VA）, best corrected visual acuity （BCVA）, eye axial length, and refraction and so on. All patients were followed up for 6 months to 1 year. Results Ex- cept one IOL was deviation because the posterior capsular was broken when implanting IOL resulted from too small incision, the others were in the right position and sticked to the posterior capsular membrane where no folds were found. The postoperative unaided visual acuity were ≥0.3 in 56 eyes, ≥0.5 in 46 eyes, 50.8 in 6 eye and ≤0.3 in 24 eyes. Except 2 patients, post operative vi- sion were not improved, whose preoperative near visual acuity were ≤0.1, the others were better than their best preoperative visual acuity. Conclusion Careful preoperative examination and phaco- emulsifcation combined with low or negative dipoter IOL BigBag can not only steady posterior cap- sular bag but also reduce the occurrence of posterior capsular membrane folds, posterior capsular cat- aracts and retinal detachment.
