In this article, Dr Johannson presents intraindividual IOL comparison follow-up results. Although similar levels of PCO development were observed for both AcrySof and Tecnis one-piece IOLs, fewer glistenings appeared in the Tecnis material, 3 years after implantation.
This follow-up study found anterior capsule opacification development and anterior capsule retraction to be more frequent 3 years after cataract surgery when an IOL with interrupted sharp optic edge at the optic–haptic junction is implanted, compared with an IOL with a continuous edge.
Fluid-based accommodating IOL technology achieved “true accommodation” in a pilot study. A multicenter study of the lens is ongoing.
Multifocal IOLs with a trifocal diffractive optic design are available outside of the United States. They provide good visual acuity for distance, intermediate, and near and appear to provide slightly better intermediate vision than bifocal diffractive multifocal IOLs.
A warm viscoelastic technique aids in the intraoperative delivery and unfolding of a hydrophobic acrylic IOL during cataract surgery.
Modifications to a reusable injector system have reduced resistance between the plunger tip and the IOL, creating a smoother delivery of the lens into the eye.
An optometrist in British Columbia has developed an IOL that his company’s website says “is capable of restoring quality vision at all distances, without glasses, contact lenses or corneal refractive procedures, and without the vision problems that have plagued current accommodative and multifocal [IOL] designs.”
A new epidescemetic keratoprosthesis implanted without total corneal trephination, is a viable alternative to corneal transplantation, according to researchers from Spain, Egypt, and Kuwait reporting in the British Journal of Ophthalmology.
Different corneal diseases present different challenges to achieving the desired refractive outcome after cataract surgery. Cornea specialist Dasa V. Gangadhar, MD, highlights measures to consider in various situations.
The unique properties of a light-adjustable lens are designed to provide predictable results and customized refractive treatments.
Despite the advent of advanced technologies-such as corneal stromal collagen crosslinking (CXL), intracorneal ring segments (ICRS), toric phakic and pseudophakic IOLs, and keratoplasty-patients with keratoconus are mostly being managed with spectacles and/or contact lenses.
Implant exchange in multifocal IOL recipients unhappy with their vision is better performed sooner rather than later. It is even better to avoid the exchange whenever possible by identifying and addressing a treatable cause for the patient’s complaints.The best strategy of all is to prevent dissatisfaction in the first place by attention to patient selection and preoperative management, said Stephen G. Slade, MD.
In his debut blog, Dr. Packer writes of a cautionary tale to physicians when stuck between the wants and needs of married patients.
Highly variable myopia shifts can occur in pseudophakic children. IOL exchange seems to be an acceptable option for treating the high myopia that can develop with lens implantation in children.However, the use of IOLs in growing eyes remains controversial, and outcomes are uncertain because of lack of data, according to Courtney Kraus, MD.
A foldable, hydrophobic acrylic IOL embedded with a small-aperture mask provided excellent visual acuity across all distances in patients who underwent monocular implantation after cataract surgery and was not associated with any visual symptoms that may occur with other presbyopia-correcting IOLs.
With a wide array of IOL options available to their foreign colleagues, U.S. ophthalmologists eagerly await the approval and availability of additional lenses.
A new intraocular mini-telescope is easy to implant through a small incision and has optimized optics so that it reliably provides good quality vision.
Alcon recently announced a partnership to in-license Google’s smart lens technology, but many questions remain. What will this new product bring to eye care and will it change ocular medicine?
Rayner Intraocular Lenses Ltd. have launched a new injector, RaySert Plus, in the United States market after receiving 510(k) clearance from the FDA.
The recent agreement between Valeant and Croma-which would provide for the distribution of Croma’s ophthalmology products in Western Europe-is expected to expand Bausch + Lomb’s (B + L) ophthalmic portfolio in the United States.
The European Society of Cataract and Refractive Surgeons (ESCRS) never fails to entice ophthalmology with cutting-edge technology, and the XXXII Congress in London has not disappointed attendees. This year’s congress has displayed a wide range of new technologies from cataract and refractive platforms to diagnostic units to surgical instruments. From all the equipment presented, IOL advances have again captured the attention of attendees.
The Synchrony dual-optic accommodative intraocular lens (Abbott Medical Optics) seems to be clinically safe and effective after 2 years of follow-up. The visual function at intermediate and far improved rapidly postoperatively. Half of patients require a +1 D prescription for near vision.
When consulting with patients who present with decreased vision due to cataracts, ophthalmologists need to remember their role as physicians first, suggest the authors. The primary goal of the office visit is to address the complaint and the solution in entirety before moving into outcomes.
Among the 2013 ASCRS clinical survey results on astigmatism, findings showed that 57% of physicians saw benefits associated with femtosecond laser arcuate incisions compared with conventional manual incisions. Other trends were identified from the more than 1,000 physician responses.
Early treatment of pediatric cataracts is crucial, with proper consideration being given to age and the type of postoperative correction to be used.
