Refractive

A pupil expansion device is flexible, yet stable and can easily be inserted and removed for cataract surgery procedures.

Analyses of predicted refractive outcomes using different IOL calculation formulas suggest possible strategies for increasing predictability in eyes with mild or moderate keratoconus.

Researchers explore the efficacy and reliability of laser vision correction for the treatment of residual refractive error after refractive lens exchange.

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.

This 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.

A small review recently found 28 different names for the procedure, and the chances are there are even more currently in use.

Intraoperative aberrometry enables better outcomes for demanding and challenging patients according to new study.

The number of presbyopia correcting options has increased along with the size of the presbyopic market. Clear lens exchange (CLE) is becoming a popular option as a result of the latest generation of intraocular lenses that have been shown to offer spectacle independence to a high proportion of patients. In this article, Mr Chitkara presents the 1-year results of his small study evaluating CLE with implantation of the Diffractiva-aA lens.

Here, Dr Verdoorn presents his experiences with the Raindrop Near Vision Inlay, which he has found to be a successful option for presbyopic patients.

Since scleral implant surgery for presbyopia correction was first introduced, numerous enhancements have standardized and simplified the procedure. In this article, Dr Cummings discusses binocular visual improvement outcomes observed with a new generation implant system, and explains which patients may benefit from the procedue.

A new sequentially shifting wavefront device for intraoperative aberrometry provides continuous feedback on refraction during cataract surgery.

Taking a look at the improvements made this past year in refractive accuracy through several new technologic evolutions.

A look at how crosslinking applications, topography-guided ablations, along with the introduction of the Symfony lens, dominated refractive surgery this past year.

The effect of astigmatism varies with different factors and can affect patient satisfaction with multifocal or monofocal IOLs.

Refractive surgery screening devices do not provide results that are interchangeable.

Kenneth J. Rosenthal, MD, explains the advantages of an add-on sulcus-based IOL for correcting refractive errors in eyes that have undergone cataract surgery with in-the-bag IOL implantation.

A diffractive trifocal IOL is novel technology that delivers good near, intermediate, and far vision and has other advantages.

FDA approval of topography-guided PRK brings additional benefits to small subset of patients

Early reports are positive for point spread function technology, which is the latest in a long line of attempts to replace the phoropter for refraction.

Loteprednol etabonate 0.5% provides enhanced safety, efficacy, comfort for refractive surgery

PRK less invasive; procedure more compatible in patients with suspected keratoconus

Pre-existing dry eye should be identified and controlled before surgery is considered

LASIK can be an option after management to normalize ocular surface

Uncertainty outweighs risks, benefits of simultaneous crosslinking to prevent postLASIK ectasia

How lens position, capsulotomy size/shape affect centration, visual outcomes
