中文摘要 | 無需縫合之白內障晶體乳化術具術後視力恢復快,符合經濟效益等優 點,為了解此項術式對病患角膜曲率之影響,作者收集20白內障病眼,比較其術 後一週、一個月及二個月後之角膜散光變化。研究結果顯示手術引發之散光於術 後一週最大,為1.09±0.68D,一個月及兩個月後分別為0.59±0.32D、0.71±0.61D。 術後散光與術前散光差別在一個月及二個月時分別有72及88患眼在±0.5D內。追 蹤一個月時,有85病人最佳視力可達0.5以上。吾等發現無縫合性技術僅在手術 切口造成短暫性,輕微角膜扁平的效應,且此無縫線式白內障之手術引發散光較 傳統的縫線手術明顯減低。為加速術後視力恢復,選擇手術切口於術前角膜弧度 最陡之軸位應是較合理之選擇。(慈濟醫學1996:8:307-311) |
英文摘要 | To evaluate the effect of sutureless phacoemulsification on the comeal topography, we compared the cornealcurvatures of 19 cataract patients (20 eyes) with keratometery preoperatively and at one week, one month, two monthsintervals postoperatively. Our results showed that 55 of the operated eyes had the net astigmatism changes within±0.5D at one week; the proportions increased to 72 and 88 at one month and two months' follow-up. The surgicalinduced astigmatism at one week postop was 1.09±0.68D, and was reduced to 0.59±0.32D and 0.71+0.61D at onemonth and two months postop respectively. Eighty-five percent of the operated eyes achieved the best corrected visualacuity 20/40 or better at one month's follow-up. According to the topographic change, only a mild transient flatteningeffect on the corneal curvature along the incisional axis. It appeared that with the sutureless technique the surgicalinduced astigmatism was much less when compared with the traditional sutured procedure. To achieve a rapid visualrestoration, preoperative determination of the steepest meridian of corneal curvature, which served as the axis of theincision, is warranted when performing the sutureless phacoemulsification.
