眼内レンズ挿入後の合併症に対するYAGレーザーの適応症について検討した。その適応症はフィブリン膜形成,後嚢混濁,後発白内障であり,それぞれ30眼(26.1%),19眼(16.5%),66眼(57.4%)で総数115眼であった。フィブリン膜形成は、対象症例(958眼)中で3.13%に認められ,糖尿病,網膜色素変性症,狭隅角緑内障,外傷の疾患で高頻度にみられた。後嚢混濁は白内障術後1週間から6か月の間にYAGレーザーが施行されていた。後発白内障は平均28か月でYAGレーザーが行われ,白内障術後最高視力とYAGレーザー実施時の視力差は0.5であった。
We performed Q-switched YAG laser treatment in 115 eyes for postoperative complications of pos-terior chamber lens implantation including: fi-brinous membrane in pupillary area 30 eyes, resid-ual opacification of the posterior capsule 19 and aftercataract 66 eyes. Fibrinous membrane forma-tion developed in 3.13% of 958 eyes. It was more common in eyes with diabetes, pigmentary retinaldegeneration, narrow angle glaucoma and prior ocular trauma. YAG laser treatment for residual opacification of the posterior capsule was perfor-med 1 week to 6 months after surgery. In eyes with aftercataract, YAG laser was applied after an average of 28 months after surgery. The differance in the visual acuity before and after YAG laser treatment averaged 0.5 in eyes with aftercataract.
