Presbyopia therapy: Comparison of corneal versus lens-based optionsThe authors assess the quantitative and qualitative aspects of vision following various lens- and corneal-based therapies for presbyopia. In many cases the KAMRA corneal inlay offers a long-term solution. It can easily be removed if the patient is not satisfied with the outcome.
Presbyopia compensation with femtosecond laserThis article discusses the advantages and limitations for surgical compensation of presbyopia with the femtosecond laser using corneal inlays and the Intracor technique.
Intraoperative aberrometry can help improve refractive resultsIntraoperative aberrometry aphakic and pseudophakic readings can be comparable with careful control of surgical variables. Both readings can be useful to predict postoperative manifest refraction.
Refractive surgery for special needs children: The time is nowThe time for refractive surgery for special needs children seems to be at hand, considering that advancements in laser and IOL technologies have been proven to be efficacious. Correcting a special needs child’s vision can reduce fearfulness and improve their behavioral challenges.
Optimizing individual outcomes through staged cataract surgeryIn this third of a four-part column, Arun C. Gulani, MD, continues the discussion on staged cataract surgery.
Device improves irregular astigmatism in pseudophakic eyesA pinhole implant placed in the ciliary sulcus can improve visual acuity and reduce dysphotic symptoms in pseudophakic eyes with irregular corneal astigmatism. Implantation is even easier with the latest version of the investigational device
Pupil expander manages unique needs of small pupilsA pupil expansion device is flexible, yet stable and can easily be inserted and removed for cataract surgery procedures.
IOLs in cataract surgery – do the risks outweigh the benefits in infants?This article presents recent epidemiological findings outlining the association between cataract surgery, potential visual acuity gains, glaucoma and the risk of undergoing additional general anaesthesia in under 2s. The authors of the original study concluded that use of IOLs in cataract surgery in young children should be critically reassessed, particularly in settings/communities where close, long-term follow-up is challenging.
The dexamethasone nanowafer: A novel method of drug delivery for dry eye diseaseThis review presents a therapeutic nanowafer as an alternative to eye drops for dry eye disease, designed to enhance efficacy and improve patient compliance to treatment. In an experimental animal study, the novel dexamethasone nanowafer drug delivery system was comparable in efficacy to twice-daily dexamethasone eye drop treatment and has the potential to minimise risk of cataract formation and glaucoma.
IOL power calculation for keratoconus: One-size strategy does not fit allAnalyses of predicted refractive outcomes using different IOL calculation formulas suggest possible strategies for increasing predictability in eyes with mild or moderate keratoconus.
