| Summary: | AIM: To analyze and study reasons of high intraocular pressure(IOP)after phacoemulsification and intraocular lens implantation and its therapeutic methods. <p>METHODS: Totally 1 258 cases(1 318 eyes)of cataract treated with phacoemulsification and intraocular lens implantation were retrospectively analyzed in our hospital from January 2006 to October 2012.<p>RESULTS: Among the 1 318 eyes, IOP occurred in 54 eyes(about 4.10%). The IOP reached the peak mostly 2 to 4 hours after the surgery, up to 22-60mmHg. One eye with congenital cataract; 2 eyes with traumatic cataract; 15 eyes with diabetes; 12 eyes with hypertension; 2 eyes with chronic pigment meningitis; 1 eye after vitrectomy; 11 eyes with high myopia; 10 eyes with unconsolidated systemic disease. Part of the cortical residual and the viscoelastic agent residue or crystal posterior capsular rupture vitreous overflowed into the anterior chamber or severe inflammatory reaction was observed through slit lamp in high IOP patients.<p>CONCLUSION: Viscoelastic agent residue and inflammation is the main reason of IOP. With diabetes, high myopia, chronic pigment meningitis, ocular trauma of disease such as cataract patients are more prone to IOP.
