摘要

AIM:To evaluate the possible effects of phacoemulsification cataract surgery on ocular hemodynamics.·METHODS:In this prospective study,intraocular pressure(IOP),pulsatile ocular blood flow(POBF),and ocular pulse amplitude(OPA) were measured pre-operatively(baseline) and at 1 week and 3 weeks postoperation in 52 eyes of 26 patients(mean age 63.15±10.25 years) scheduled for unilateral phacoemulsification cataract surgery with intraocular lens implantation.In all of the eyes,a blood flow analyzer(Paradigm DICON;Paradigm Medical Industries Inc.;USA) was used to obtain measurements of IOP,POBF,and OPA.The data obtained from operated eyes were compared statistically to untreated fellow phakic eyes of the patients.·RESULTS:For operated eyes,the mean baseline IOP,POBF,and OPA values were 15.9±4.64mmHg,17.41±4.84μL/s,and 2.91 ±1.12mmHg,respectively.The IOP,POBF,and OPA values were 17.19 ±4.34mmHg,17.56 ±6.46μL/s,and3.12 ±1.1mmHg,respectively,in the nonoperated control eyes.Statistically significant differences from baseline measurements were not observed 1 week and 3 weeks postoperation for the operated or nonoperated eyes.There were also no statistically significant differences in any measurements between the operated and nonoperated eyes in all the examination periods(P 】0.05for all).·CONCLUSION:Uncomplicated phacoemulsification surgery does not affect ocular hemodynamics in normotensive eyes with cataracts.
