. We studied 129 eyes which were undergoing extracapsular cataract extraction with IOL‐implantation. The amount of residual Healon® had a clearcut effect on the IOP elevations postoperatively. In eyes operated on with the intercapsular technique, pressure elevations and the mean values during the first 6 postoperative hours were significantly higher than in eyes operated on with the planned ECCE (can opener‐technique) ( P <0.01). The pressure elevations reached the maximal values 8–12 h postoperatively and had normalized already at 24 h in most cases, except in glaucomatous eyes which at that time had significantly higher mean IOP values than the non‐glaucomatous eyes ( P <0.01). When operations were done with an air bubble no clearcut postoperative pressure increases could be observed. Our study indicates that a comparatively small amount of Healon® may cause a pressure elevation and the amount left in the eye has a greater effect upon the level of the pressure than the duration of the pressure elevation. The less we inject Healon® into the eye and the more we avoid leaving it there, the less risk we have of the possibility of vision deteriorating high postoperative intraocular pressure.
