NSAID activity at trough drug levels
June 23rd 2008Animals undergoing lens removal surgery were treated with non-steroidal anti-inflammatory drugs pre- and postoperatively. On the first day after surgery, aqueous humor samples were taken at times corresponding to trough drug levels. The mean aqueous prostaglandin E2 concentration was significantly lower in animals being treated with ketorolac 0.4% (Acular LS, Allergan) compared with those receiving bromfenac 0.09% (Xibrom, ISTA Pharmaceuticals).
Ophthalmologists debate whether ectasia is preventable
June 23rd 2008In a point-counterpoint debate at the annual meeting of the American Academy of Ophthalmology, one clinician contended that the rate of post-LASIK ectasia is declining and that, with careful screening and other preparatory steps, the rate of ectasia can be kept very low. The counter-argument by another clinician suggested that the multifactorial basis of ectasia as well as unknown risk factors make it impossible to prevent a certain percentage of cases from developing.
Aspheric IOL offers better contrast sensitivity
June 23rd 2008In a prospective, randomized, contralateral study of 75 adults, eyes in which an aspheric IOL (AcrySof IQ model SN60WF, Alcon Laboratories) had been implanted demonstrated better mesopic contrast sensitivity, significantly less spherical aberration, and significantly less total higher-order aberrations compared with eyes in which a standard spherical IOL (AcrySof model SA60AT, Alcon Laboratories) had been implanted. Cumulative uncorrected visual acuity and best-corrected visual acuity were equivalent between both groups.
Advanced glycation in diabetic patients leads to cataracts
June 16th 2008The higher level of advanced glycation end products (AGE) in senile diabetic patients may correlate to a higher rate of cataract development, according to a study published in the May?June 2008 issue of the Journal of Diabetes and its Complications.
Multifocal IOLs in glaucoma patients
June 16th 2008Further study is needed to establish the role of multifocal IOLs in eyes with glaucomatous damage, according to Ike Ahmed, MD, who was speaking during the glaucoma subspecialty day at the annual meeting of the American Society of Cataract and Refractive Surgery.
Is cataract surgery the best way to lower IOP?
May 22nd 2008Extraction of cataracts lowers intraocular pressure (IOP) to normal levels in glaucoma patients, and may in fact be a better treatment option than combined surgery, according to a study presented at this year's meeting of the Italian Society of Ophthalmology.
LASIK corrects residual error after multifocal IOL implantation
May 19th 2008Wavefront-guided LASIK is safe and effective in correcting residual refractive error after diffractive multifocal IOL implantation, according to a study published in the March 2008 issue of the Journal of Refractive Surgery.
Post-LASIK contact lens launched
May 12th 2008A hybrid contact lens designed for eyes that have suffered corneal trauma or undergone either refractive surgery or penetrating keratoplasty has been launched by SynergEyes Inc, US. The SynergEyes PS lens can also be used in eyes with degenerative corneal conditions.
