The implantation of transsclerally sutured posterior chamber lenses (P
CL) leads to greater trauma to the eye than endocapsular PCL implantat
ion. Persistent breakdown of the blood-aqueous barrier might impair th
e postoperative long-term prognosis. Using laser-tyndallometry, we qua
ntified the disorder of the barrier function during the early postoper
ative phase and in the long-term postoperative course for both surgica
l procedures. During the first 3 postoperative days, flare Values were
three times higher in the group with transsclerally sutured PCL than
in the conventional PCL group. Cell counts after transscleral suture f
ixation (27.7 +/- 18.3/0.075 mm(3)) decreased slightly during the firs
t 5 postoperative days. In contrast,the conventional PCL group regaine
d the preoperative level (2.5 +/- 5.1) after 3 days. After 3 months, n
o significant differences in flare values and cell counts were seen be
tween the two groups. After implantation of transsclerally sutured pos
terior chamber lenses, breakdown of the blood-aqueous barrier was init
ially more pronounced than in conventional PCL implantation. However,t
he barrier function was re-established equally in both groups in the l
ong term. No signs of a persistent disorder of the barrier were found.
