Cataract & Refractive

Incorrect IOL power is one of the most frequent reasons for IOL exchange following cataract surgery. Different options for the correction of residual refractive errors are being developed, including piggyback IOLs, light-adjustable lenses and multicomponent IOLs.

Topography disparity can even provide a useful parameter for diagnosing the subclinical form of the disease, said David P. Piñero, PhD, and colleagues from the Medimar International Hospital, Alicante, Spain.

Cataract surgery appears to reduce the risk of glaucoma in eyes with pseudoexfoliation (PEX) syndrome, researchers said.

Rounded phaco tips reduce the risk of posterior capsule rupture, increasing the safety of phacoemulsification. The Dewey Radius Tip, which is used exactly like a sharp-edged phaco needle, has rounded edges. This reduces the risk of posterior capsule rupture during cataract surgery.

Five years of experience with the Rayner T-flex aspheric IOL show it to be a safe, highly effective long-term method of correcting the widest possible range of sphere and cylinder errors in pseudophakic patients with pre-existing corneal astigmatism.

The combination of MICS and MIGS can offer an effective surgical treatment for POAG when the reduction of IOP following cataract surgery alone is not sufficient to reduce a patient’s need for glaucoma therapies.

Corneal asphericity, OCT angiography, and balance control issues in glaucoma patients are analyzed in this industry update roundup.

In this article, the authors discuss how WF?guided and WF-optimized LASIK performed on hyperopic patients can provide similar results in terms of safety, contrast sensitivity and refractive error.

In SMILE the anterior-most stromal lamellae remain intact postoperatively. Here, the author discusses the biomechanical advantages of preserving the stronger anterior stroma and the resulting effects on spherical aberration control and optical quality.

PRK has been an established method for laser vision correction for nearly 30 years, however, its popularity has reduced somewhat due to the advent of LASIK. With a recent renewed interest in surface ablation techniques some modifications have been made to alleviate disadvantages of the procedure. In this article, the authors highlight their clinical experience of TESA in myopic eyes with or without astigmatism.

Anterior capsulotomy triggers an increase of prostaglandins in the aqueous humour immediately after FLACS, according to researchers from Ruhr University Eye Hospital, Bochum, Germany.

Researchers using the AREDS lens grading scale have found that long-term clinically relevant outcomes can be predicted by 2-year changes in severity of lens opacities.

When performing phacoemulsification, using a venturi-based vacuum may result in reduced clearance time of lens material compared to a peristaltic-based vacuum, according to new research.

More research required to clarify the short- and long-term effects of femtosecond laser-assisted cataract surgery (FLACS) on the corneal endothelium.

Femtosecond laser-assisted capsulotomy resulted in better circularity and more predictable size compared with standard manual continuous curvilinear capsulorhexis (CCC) in a prospective, randomized clinical study by researchers in Italy.

Anterior capsulotomies may be created safely and efficaciously using a femtosecond laser system (Catalys Precision Laser System, Abbott Medical Optics), according to a study published online in the Journal of Cataract & Refractive Surgery.

Extensive pars plana vitrectomy and cataract extraction can significantly improve visual acuity in juvenile idiopathic arthritis patients suffering from severe ocular complications of uveitis.

When compared with eyes of normal axial length, high-myopic pseudophakic eyes with posterior staphyloma had significantly less internal coma and less coma variations during mydriasis, according to recently published research.

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.
