AIM: To investigate the related factors and solutions of early high intraocular pressure(IOP)after intraocular lens(IOL)implantation in cataract phacoemulsification.

METHODS:This retrospective cases series collected 658 patients(726 eyes)after IOL implantation in cataract phacoemulsification from Jan.2014 to Jan.2016 in the Second People's Hospital of Beihai.

RESULTS:High postoperative IOP happened in 38 eyes(5.2%), and the range was from 21mmHg to 55mmHg. Most of them happened between 6h to 24h after surgery. The main causes of high IOP were 24 eyes of viscoelastic residue(63.2%), 9 eyes of uveitis(23.7%), 2 eyes of hyphema(5.3%), 2 eyes of residual cortex(5.3%)and 1 eye of pouch blockage syndrome(2.6%). All cases were controlled under 21mmHg after 3d treating with drugs, anti-inflammatory and anterior chamber tapping. YAG laser therapy was performed in 1 eye of pouch blockage syndrome.

CONCLUSION: Viscoelastic residue and inflammation were the main causes of high postoperative IOP in phacoemulsification. With comprehensive preoperative evaluation, surgical skills improvement and effective response, the high postoperative IOP would be effectively prevented as well as the recovery of visual acuity.
