Cell loss
after small-incision DSEK is significantly influenced by surgical
technique
This retrospective review of 500 consecutive
cases of primary Descemet stripping with endothelial keratoplasty (DSEK)
identifies three surgical factors that influenced endothelial cell loss
six months after surgery. Cell loss was significantly less when
single-point fixation forceps were used for graft insertion and in grafts
that did not require repositioning. Combining DSEK with cataract
extraction also resulted in less cell loss. Ophthalmology, May
2008
Avastin
appears to have the same low endophthalmitis rate as
Lucentis
This retrospective review included 10,254
intravitreal anti-VEGF injections ¨C including pegaptanib, bevacizumab and
ranibizumab ¨C performed as an office-based procedure with povidone-iodine
as the only pre-injection preparation. The incidence of suspected
endophthalmitis per injection was 0.029 percent; a rate similar to or
lower than clinical trials that mandated the use of pre-injection
antibiotics and draping of patients. There was no difference in infection
rate among the three treatments. American Journal of
Ophthalmology, May 2008
LASIK can
treat some children with hyperopic anisometropic
amblyopia
Researchers evaluated the use of unilateral
LASIK to achieve refractive balance in 32 children in whom conventional
therapy was unsuccessful. At last follow-up, which ranged from one to five
years, visual acuity improved in the amblyopic eye and was associated with
decreased anisometropia. The children achieved results similar to that of
adults with comparable refractive errors. Journal of Refractive
Surgery, May 2008
Cyclosporine
A appears to speed visual recovery after LASIK
Researchers
retrospectively compared outcomes in patients treated with cyclosporine A
0.05% after surgery to those who received the standard regimen for 12
weeks. None of the 45 patients had pre-existing dry eye. Overall, eyes in
the cyclosporine A group showed dramatic improvement in UCVA recovery at
one week postop, with 44.9 percent of cyclosporine A eyes obtaining UCVA
of 20/15 compared with 22.2 percent of eyes in the standard treatment
group. Journal of Refractive Surgery, May 2008
Animal study
shows levofloxacin may be an alternative to standard therapy for
endophthalmitis
Researchers evaluated the efficacy of
intravitreal 1.5% levofloxacin compared to combined vancomycin and
ceftazidime in rabbits inoculated with either S epidermidis,
S aureus or P aeruginosa. In all three models of
endophthalmitis, levofloxacin treatment produced 3¨C5 log reductions in
CFU/ml of vitreous relative to that in untreated eyes, and there were no
significant differences in CFU/ml between the two antibiotic-treated
groups. British Journal of Ophthalmology, May 2008

ISRS/AAO NEWS
ISRS/AAO Web
site now features YOU
This new feature, Find a
Refractive Surgeon, is an online directory of all participating
ISRS/AAO members, accessible to both physicians and patients. You can find
it on the home page of our Web site. A more comprehensive directory than
the former Locate and ISRS Doctor service, Find a Refractive Surgeon
allows visitors to search for a refractive surgeon/practice in their
area by last name, city, state, zip or country. It also provides office
and education information for each member. As a member of ISRS/AAO, when
you are logged into the ISRS/AAO Web site, you can view additional
information about your colleagues, including e-mail address, committee
membership and awards received. If your practice is not listed or you have
changes, please e-mail isrsaaoprofile@aao.org with the
correct information.
It¡¯s not too
late to register for the ISRS/AAO Annual Regional Meeting next week in
Canc¨²n, Mexico
Registration is free to ISRS/AAO members,
but you still need to register. The meeting, Refractive and Cataract
Surgery: Today and Tomorrow, will take place 29 to 31 May, 2008.
Please contact us at registration@aao.org if you have
any questions.
