While the accuracy of IOL power selection has advanced since the early days of phacoemulsification, the selection of the proper IOL power is always in the background when a surgeon performs cataract surgery, Dr. Hill said.

With myopia on the rise, greater understanding of genetic and environmental factors is needed to refine interventions that may curtail disease progression.

Severe myopia affected the attitudes of both Theodore Roosevelt and Ronald Reagan, but in opposite ways, according to biographer Edmund Morris.“Since both of them became aware of their myopia in their early teens, it was obviously a formative experience for both of them,” Morris told Ophthalmology Times.

The 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.

This article discusses the advantages and limitations for surgical compensation of presbyopia with the femtosecond laser using corneal inlays and the Intracor technique.

Intraoperative aberrometry aphakic and pseudophakic readings can be comparable with careful control of surgical variables. Both readings can be useful to predict postoperative manifest refraction.

A 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

In this third of a four-part column, Arun C. Gulani, MD, continues the discussion on staged cataract surgery.

The 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.

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.
