Cataract & Refractive

Two trifocal IOLs enabled patients to have "a useful third focus for intermediate vision", but also resulted in increased background halos and reduced distance visual quality compared with a multifocal IOL, according to new research.

Patients with myopia of greater than -6.00 dioptres (D) who underwent femtosecond laser-assisted LASIK, experienced a more significant decrease in corneal hysteresis, corneal resistance factor, and p1 and p2 areas than patients who underwent small incision lenticule extraction (SMILE).

Monovision correction and multifocal IOLs work well for correcting distance vision, with multifocal IOLs reducing the need for glasses but significantly increasing dysphotopsia for those who underwent implantation.

Daily supplementation with selenium and/or vitamin E is unlikely to have a large preventive effect on the development of age-related cataracts, according to data from a recent study.

Cataract surgery is associated with a reduced risk of dementia later in life, researchers in Taiwan have found.

It's important to evaluate tear osmolarity during surgical planning to ensure that pre-surgical keratometry readings are not compromised by hyperosmolarity of the ocular surface.

Endoscopic cyclophotocoagulation (ECP) and phacoemulsification cataract extraction, when combined, result in greater reduction of IOP and need for IOP-lowering medications over 3 years compared with cataract extraction by itself.

Intracameral cefuroxime can help prevent endophthalmitis after cataract surgery and does so cost-effectively, according to Spanish researchers who conducted a systematic literature review.

Here, the author discusses the findings of a recent study examining the efficacy and safety of the Raindrop Near Vision Inlay in emmetropic presbyopes and then compares these with results from an unpublished study on patients with low hyperopia.

The standard of care is implantation with an IOL, and with the introduction of a new lens to the European market, Dr Hamid and colleagues conducted a small trial to analyse the differences between this new option and other available lenses. Here, he presents his findings.

In this article, Dr Conrad-Hengerer discusses a recent study investigating the impact of femtosecond laser-assisted surgery on anterior chamber flare values and macular thickness compared with standard phaco.

Prof. Dick discusses the challenges posed by a small pupil in femtosecond laser cataract surgery and the options that are available to surgeons to overcome pupil constriction.

A small-aperture corneal inlay (Kamra, AcuFocus, Irvine, California, USA) for presbyopia yielded superb results in an analysis of long-term data.

Controversy continues over whether the femtosecond laser provides advantages in cataract surgery that justify its added cost.

Advanced DNA testing for congenital cataracts can quickly and accurately diagnose a number of rare diseases marked by childhood blindness, according to a study recently published online.

The duration and pattern of action of pain-suppressing nonsteroidal anti-inflammatory drugs (NSAIDs) used prior to photorefractive keratotomy (PRK) varies with the NSAID used, according to South Korean researchers.

Light-adjustable intraocular lenses (IOLs) provide near-emmetropic refractive outcomes and good uncorrected distance visual acuity that remains stable over time, according to a recent study.

A stable IOL, decreased pseudophacodonesis and improved graft fixation are the benefits of combining Descemet membrane endothelial keratoplasty with glued intrascleral haptic fixation of a posterior-chamber IOL in patients with aphakic or pseudophakic bullous keratopathy, according to recently published research.

Removal of a cataract and implantation of an intraocular lens (IOL) improves overall sleep quality and sleep latency, according to a study published online before print.

When performing corneal collagen crosslinking (CXL), ophthalmologists should monitor the keratoconus index and the index of height asymmetry garnered from the Scheimpflug camera, because changes in values of these indices are independent from initial corneal thickness.

It is relatively safe and effective for infants to undergo primary IOL implantation for the correction of aphakia after having one cataract removed, according to new research out of China.

The addition of diquafosol tetrasodium (DQS) to a regimen of artificial tears and sodium hyaluronate helped relieve the symptoms of persistent dry eye in patients who had undergone laser in situ keratomileusis (LASIK), according to recent research.

In this article, Dr Kov?cs discusses his recent study evaluating whether femtosecond laser-assisted capsulotomy has an effect on the incidence of PCO when compared to the manual technique.

In this article, the authors discuss their research into alkylphosphocholine coated IOLs, which may offer some hope in the prevention of PCO in the future.

A diffractive trifocal IOL (FineVision, PhysIOL) provides a peak modulation transfer function for intermediate vision.
