[Observations on the intraocular pressure after extracapsular cataract extraction].

The author observed the IOP of 32 eyes after extracapsular cataract extraction with posterior chamber intraocular lens implantation. The IOP was elevated in all cases, over 0.67 kPa (5 mmHg) in 22 cases, over 1.33 kPa (10 mmHg) in 12 cases, and the highest was 5.05 kPa (38 mmHg). The peak of elevation was at 24 hours after operation and most cases resumed the preoperative levels in 48 hours. The IOP of eyes with intracameral carbachol was significantly lower than that of those without at 6 hours after operation, but the difference became insignificant after 24 hours.
