Accurate lens position, corneal power needed for calculations in post-refractive surgery patients
Calculating the correct IOL power for a patient who has undergone previous corneal refractive surgery is a challenge. Miscalculations in these patients have led in some cases to large “refractive surprises” requiring lens exchange or a secondary piggyback IOL, said Jack T. Holladay, MD, MSEE, FACS.
Back in school, kids’ eyes may be safer
A young boy is more prepared to expect a line drive during a Little League game than to be hit in the eye by a toy car thrown by his little sister as he surfs the Internet. But household trauma is a more common cause of eye injury than organized sports.
Keep accurate account of enhancement rate with detailed patient records, surgeon says
Surgeons can maintain an accurate record of their enhancement rates by keeping a monthly log of laser procedures, outcomes and surgical criteria, according to Daniel S. Durrie, MD.
Nurses, lay screeners achieved similar sensitivity in detecting vision problems in children
Nurses and lay screeners achieved similar levels of sensitivity using several different methods when screening preschoolers for amblyopia, strabismus and refractive errors, according to outcomes from the Vision in Preschoolers Study.
Uveitis recurrence rate lowered, adjunctive therapy reduced with implant
FORT LAUDERDALE, Fla. — Patients who received a sustained-release fluocinolone acetonide implant had a significantly lower rate of uveitis after implantation than in the year before implantation, according to Glenn J. Jaffe, MD. The need for adjunctive therapy was also reduced in treated eyes, he said.
NIH chief sees shift toward prevention in research
FORT LAUDERDALE, Fla. — A shift in research focus from disease treatment to disease prevention, now under way at the National Institutes of Health, is creating “much excitement for advancement in the field of vision research,” said Elias A. Zerhouni, MD, director of the NIH.
Vertex distance important for many power calculations
Vertex distance is an essential component when determining the correct power for contact lenses, excimer laser treatments and phakic IOLs. The measurement should always be included in power calculations, said Jack T. Holladay, MD, MSEE, FACS.
Lawsuits filed against Alcon for LADARVision
Several lawsuits have been filed against Alcon for alleged performance problems with its LADARVision 4000 Excimer Laser System. An online review of active litigation by Ocular Surgery News identified six cases by physicians and patients against the maker of the laser system.
Aspheric treatments reduce spherical aberration after cataract, refractive surgery
Applying aspheric treatments to cataract and refractive surgery procedures can significantly reduce spherical aberration and the consequent effects of glare and haloes, improving postoperative visual results, said Jack T. Holladay, MD, MSEE, FACS.
Annual survey finds LASIK up 26% in U.S.
Other notable findings of the survey of U.S. members of ASCRS included an overwhelming preference for acrylic IOLs, a unanimous interest in accommodating IOLs and a near-doubling of the use of clear corneal incisions from 5 years ago among the respondents.
