Effectively treating dry eye, blepharitis and other eye surface problems before and after LASIK and cataract surgery is essential to achieving good surgical outcomes, according to a prominent cataract and refractive surgeon.
As many as 50 percent of older Americans needing cataract surgery and 30 percent of younger patients who desire elective LASIK eye surgery show [Read More …]
Surgeon recommends careful management of eye surface problems before LASIK, cataract surgery
January 27, 2010Expedited cataract surgery improves vision but does not reduce fall risk
January 20, 2010Prompt cataract surgery in older patients diagnosed with cataracts improves visual acuity but does not appear to significantly reduce the risk of potentially injury-causing falls among this population.
That’s the conclusion of Canadian researchers in a report published in this month’s issue of the Journal of Cataract and Refractive Surgery.
The investigators conducted a systematic review of [Read More …]
LASEK surgery reduces pre-operative straylight associated with glare, study finds
January 13, 2010Several studies have pointed out that a potential side effect of laser eye surgery is post-operative glare.
Researchers in Belgium have found just the opposite: LASEK eye surgery appears to reduce pre-operative retinal straylight, which is a potential source of glare. The results of their study suggests patients undergoing LASEK for the correction of myopia may [Read More …]
Flexivue corneal implant for presbyopia correction receives European market approval
January 6, 2010Flexivue, a small corneal implant designed to correct presbyopia, recently received CE certification for sales of the device within the European Economic Area (EEA).
The CE mark certifies that the implantable micro-lens meets European Union consumer safety, health and environmental requirements.
The approval was announced in a press release issued last month by Presbia, the Amsterdam-based ophthalmic [Read More …]
All-laser LASIK associated with fewer flap-related complications after enhancements
December 30, 2009Eyes that have undergone LASIK eye surgery with the corneal flap created with a femtosecond laser may be less likely to develop epithelial ingrowth if an enhancement (re-treatment) surgery is needed, according to a study published last month in Journal of Refractive Surgery.
Researchers in Indianapolis, Ind. reviewed the results of 272 consecutive LASIK enhancements performed [Read More …]
Toric phakic IOL successfully corrects high myopia and high astigmatism in Asian eyes
December 23, 2009The Visian Toric Implantable Collamer Lens (STAAR Surgical, Monrovia, Calif.), a premium type of phakic IOL, safely and effectively corrects high myopia and high astigmatism in Asian eyes, according to researchers in Hong Kong.
Forty-four eyes of 29 Asian patients with between -6.00 and -18.25 diopters (D) of myopia and -1.00 to -4.50 D of astigmatism [Read More …]
Dry eye after all-laser LASIK is mild and improves after three months, study finds
December 16, 2009Dry eye after all-laser LASIK with a femtosecond laser-created flap is mild and typically improves within three months, according to a new study by researchers at the University of Michigan’s W.K. Kellogg Eye Center.
The study was designed to determine whether corneal sensation and signs and symptoms of LASIK-induced dry eye are affected by varying the [Read More …]
Custom PRK corrects moderate myopia better than wavefront-guided LASIK, study finds
December 9, 2009A new study conducted in Brazil has found that wavefront-guided PRK with application of low-dose mitomycin C (MMC) is more effective than wavefront-guided LASIK for the correction of moderate myopia.
Eighty-eight eyes of 44 patients with moderate myopia were randomly selected to undergo either wavefront-guided (custom) PRK or custom LASIK. The mean amount of pre-operative myopia [Read More …]
Implantation of corneal rings followed by corneal collagen cross-linking provides more effective keratoconus treatment
December 2, 2009Researchers in Turkey have found that implantation of intrastromal corneal ring segments followed by corneal collagen cross-linking (CXL) therapy provides more effective treatment of progressive keratoconus than CXL followed by corneal ring segment implantation.
Keratoconus is a progressive eye disorder characterized by thinning and bulging of the cornea into an irregular cone-shaped profile, causing blurred vision [Read More …]
Bilateral multifocal IOLs produce good depth perception after refractive lens exchange
November 30, 2009Refractive lens exchange (RLE) with implantation of AcrySof ReSTOR multifocal intraocular lenses (Alcon, Inc.) produces good depth perception in patients with normal binocular vision prior to surgery, according to a new European study.
Researchers in Spain and Portugal evaluated the stereoacuity of 15 farsighted subjects who elected to undergo RLE in both eyes for the correction [Read More …]
