(R1-7AM-15) 後房レンズ毛様溝縫着術を行った110例110眼の術後成績を検討した。このうち1次挿入眼は73眼(1次挿入群),2次挿入眼は37眼(2次挿入群)であった。裸眼視力は両群ともにほとんどの症例で改善した。眼圧は1次挿入群で一時的な上昇を認めた。術後12か月での角膜内皮細胞数減少率は,1次挿入群,2次挿入群それぞれ14,4±12.6%,15.4±12.1%であった。術後合併症として前房・硝子体出血,眼内レンズの偏位・傾斜,網膜剥離などを認めたが,両群間の発症率に有意差はなかった。当術式は視力改善手段として有用であるが術後合併症は少なくなく,慎重な経過観察が大切である。
We reviewed 110 eyes of 110 patients who underwent sulcus fixation of the posterior chamber lens. The surgery was performed as primary procedure in 73 eyes and as secondary in 37 eyes. The uncorrected visual acuity improved in 100 eyes (91%). Transient ocular hypertention was frequent in the primary group. Corneal endothelial loss one year after surgery averaged 14.4 ± 12.6% in the primary group and 15.4 ± 12.1% in the second. There was no significant difference between the both groups. Postoperative complications included hyphema, vitreous hemorrhage, tilting or dislocation of the lens, and retinal hemorrhage. There were no significant differences in their incidence between both groups. The findings show the usefulness of this surgical procedure. Due precaution is necessary because of occasional postoperative complications.
