[Disorders of the blood-aqueous barrier after phacoemulsification].
OBJECTIVE
To determine the status of blood-aqueous barrier after small incision phacoemulsification with implantation of foldable intraocular lens.


METHODS
The blood-aqueous barrier status in 64 eyes of 60 patients who underwent cataract surgery was examined using a laser flare cell meter. The protein level of anterior chamber aqueous humor was evaluated by measurement of the flare value preoperatively and postoperatively.


RESULTS
The mean preoperative flare intensity was (6.94 +/- 0.34) photon counts/ms, which increased to (26.27 +/- 1.37), (13.96 +/- 1.05), (9.07 +/- 0.43) and (7.16 +/- 0.27) photon counts/ms on days 1, 7, 30 and 90 after the surgery, respectively. Significantly statistical differences on flare values were found between preoperative data and those on days 1, 7 and 30 after surgery. The blood-aqueous barrier was recovered on day 90 postoperatively. The variables such as age, gender, eye (left/right) had no influence on the flare value. Patients with iris prolapse had a higher flare value at day 1 and day 7 after the surgery.


CONCLUSIONS
Blood-aqueous barrier after phacoemulsification with implantation of intraocular lens can be measured quantitatively by the laser flare cell meter. The blood-aqueous barrier disorders can be recovered shortly after phacoemulsification.
