同一条件下で移植された紫外線吸収人工水晶体(UV-IOL)108名112眼と紫外線非吸収人工水晶体(nonUV-IOL)134名137眼について,術後合併症や術後視力を臨床的に比較検討した.術後観察期間は平均9.60カ月(1カ月〜1年)であった.2群間には術後視力の有意差はなく,また両群とも6カ月以降の術後類嚢胞黄斑浮腫(CME)発生はなかった.UV-IOL群ではCMEは2例発生し(2/112=1.79%),フィブリン析出は5例であった(5/112=4.46%).nonUV-IOL群では,CME発生が3例(3/137=2.19%)で,フィブリン析出が1例(1/137=0.73%)であった.UV-IOLとnonUV-IOLの両者の間にはCMEを含めた術後合併症の発生率に有意差はなかった.
We tested the value of ultraviolet-absorbing intraocular lens (UV-IOL) in a consecutive series of 249 eyes in 242 subjects. UV -IOL, made by Cilco, was im-planted in 112 eyes, while conventional, UV-nonabsorb-ing chromophore intraocular lens was implanted in 137 eyes. The postoperative follow-up period ranged from 1 month to 1 year, average 9.60 months.
The incidence of cystoid macular edema was 2/112(1.8%) in the UV-IOL group, and was 3/137 (2.2%) in the non-UV-IOL group. In all the cases, the CME occurred within 6 months after surgery.
