PURPOSE: To evaluate the efficacy and safety of therapeutic application of recombinant tissue plasminogen activator (rtPA) for fibrin reaction after uneventful cataract surgery.
SETTING: Department of Ophthalmology, SSK Istanbul Hospital, Istanbul, Turkey.
METHOD: In a prospective study between January and June 2000, 26 eyes of 26 patients with fibrin reaction after uneventful cataract surgery received 3 microg of intracameral rtPA. Patients were evaluated for recurrences of fibrin reaction or complications by slitlamp biomicroscopy 2, 12, and 24 hours, 1 week, and 1 and 6 months after rtPA application. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry. Visual acuity was tested using a standard Snellen chart 1 week after rtPA application.
RESULTS: All 26 eyes had complete fibrinolysis. Three eyes (11.5%) had corneal edema that lasted fewer than 24 hours. Visual acuity improved by 0 to 7 lines in 19 patients (73.1%). No patient had an increase in IOP. At 6 months, no patient had hyphema or recurrence of fibrin reaction.
CONCLUSIONS: Complete lysis of fibrin after cataract surgery with conventional topical medications can take a long time and is not successful in some patients. Intracameral application of 3 microg rtPA was an efficient, safe method for the treatment of fibrin reaction after cataract surgery.
