Viscoelastic substance in the anterior chamber elevates intraocular pressure.

An 85-year-old man underwent an extracapsular cataract extraction OD with posterior chamber intraocular lens implantation. Sodium hyaluronate (0.3 mL) was used during the procedure, and approximately 1.0 mL of the solution, including the sodium hyaluronate, was aspirated before wound closure. The next day, the intraocular pressure OD was elevated to 60 mmHg, and it remained high despite medication. Three days later, the intraocular pressure was still high, a paracentesis was done, and viscous solution was obtained. After the paracentesis, the intraocular pressure OD normalized.
