白内障,眼内レンズ移植後早期の眼圧を非接触型眼圧計(以下NCT)によって測定することの妥当性を検証するため,59例62眼に対して手術を行い,術前,術6〜8時間後,術翌日,術2日後の眼圧を,NCTとゴールドマン圧平眼圧計(以下GAT)とで測定し,その相関を検討した。
1.術後6〜8時間から2日目までの眼圧は術前にくらべ有意に上昇した。
2.NCTの値はGATの値に高い相関を示した。
3.NCTの値はGATの値よりやや低い傾向にあった。
4.眼圧測定による合併症はなかった。
We measured the intraocular pressure (IOP) in 62 eyes following posterior chamber lens implanta-tion surgery using two methods: applanation tonometer by Goldmann and pneumatic noncontact tonometer by American Optical. IOP was measured 6 to 8 hours, one day and two days after surgery. When compared with the preoperative level, the IOP increased significantly at each of the 3 post-operative measurements. While the applanation and noncontact measurements showed parallel values, the latter tended to show lower readings than the former. There was no ocular complication due to tonometery by either method. The findings show that pneumatic tonometry is reliable and safe when performed during the early postoperative period after intraocular lens implantation.
