中文摘要 | 小瞳孔是造成晶體乳化術併發症的重要因素,也會增加環狀前囊 切開術的困難度及術後的併發症,如前囊切口收縮症,人工水晶體異位,同時在進行小瞳孔 晶體孔化術時,往往需將晶體核拉到虹彩平面進行乳化,會增加對角膜的傷害。為了避免併 發症及減少角膜的傷害,我們對於小瞳孔的白內障採用虹彩牽引鉤將瞳孔拉大,再進行乳化 術,首先用 25 號針頭在輸狀部份作四個穿刺,再將虹彩牽引鉤放入,調整矽膠套管將瞳孔 拉大,再以停止與劈開式或改良式的停止與劈開式晶體乳化術進行晶體乳化。這種方法可以 提高手術的安全性及減少對角膜的傷害,術後瞳孔的形狀也較美觀。 |
英文摘要 | Small Pupil is a risk factor of phacoemulsiication. The smaller pupil diameter also presents a challenge in performing continuous circular capsulotomy. Phacoemusification in small pupil is usually performed in the midpupil and at iris plane. It always increase corneal damage. We use iris retractor (Griehaber) to enlarge pupil so that phacoemulsification can be safely performed in the capsule bag. We use 25# needle to make 4 limbal incisions. Then iris retractors are inserted and adjusted the silicone sleeve to dilate pupil. "Stop and Chop" or "modified Stop and Chop" phacoemulsification is performed. The technique provides safe phacoemulsification condition and less corneal damage. It also recovers excellent physiologic function and cosmesis postoperatively. |
