Intracorneal ring segments may not halt progressive keratoconus in long term

WARSAW, Poland — Implantation of intracorneal ring segments in young keratoconus patients may not be able to stop the progressive nature of the disease, even though it may provided a significant short-term improvement in visual, refractive and topographic status, according to one surgeon.”Several studies have shown the efficacy of this procedure in improving [visual acuity] and flattening the central cornea. However, there is no scientific data to support that corneal ring segment implantation can halt the progressive nature of the disease,” Alfredo Vega-Estrada, MD, said at the winter meeting of (Read more...)

Accelerated corneal cross-linking may prevent astigmatism after cataract surgery

WARSAW, Poland — Accelerated corneal cross-linking may be employed in cataract surgery to manipulate clear corneal incisions and prevent surgery-induced astigmatism, according to one surgeon.”Clear corneal incisions produce dramatic changes in topometric maps. These astigmatic changes may go away with time but may otherwise be a factor of poor visual function, especially with multifocal or toric lenses,” John Kanellopoulos, MD, said at an industry-sponsored symposium held during the winter meeting of the European Society of Cataract and Refractive Surgeons.

New aspheric aberration profile shows safety, efficacy in treatment of hyperopic astigmatism

WARSAW, Poland — Aspheric femtosecond LASIK offers a reliable method for correction of hyperopic astigmatism, according to one surgeon.The prevalence of hyperopia tends to decline with age, but latent forms often become significant with the onset of presbyopia. Laser treatment is a well-established procedure but not as straightforward as it is for myopic correction, Thomas Kohnen, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Improvements in multifocal IOLs increasing opportunity for spectacle independence

WARSAW, Poland — Steady advances in multifocal IOL technology could make monofocality obsolete in the near future, according to a speaker.”Recent improvements and new designs have solved or minimized the problems of multifocal IOLs, and new options like the toric component, the low near power and the trifocal technology have increased the opportunities for spectacle independence,” Roberto Bellucci, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Intracorneal silicone injection may offer pain relief in eyes with bullous keratopathy

WARSAW, Poland — Intracorneal injection of a transparent, biocompatible hydrophobic material is a fast, minimally invasive and promising new technique for the treatment of bullous keratopathy, according to a specialist.The ideas was first developed by George D. Kymionis, MD, PhD, who observed during vitreoretinal surgery that silicone oil that penetrates into the anterior chamber works as a hydrophobic barrier, Ioannis G. Pallikaris, MD, PhD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Optimized beam profile increases efficacy of corneal cross-linking

WARSAW, Poland — The safety profile of corneal cross-linking has been confirmed through more than 15 years of follow-up, and continuous innovation has increased efficacy, according to a speaker.Summarizing cross-linking results to date and current complication rates at the winter meeting of the European Society of Cataract and Refractive Surgeons, Theo Seiler, MD, PhD, said that 1% of eyes experience two lines of vision loss. Recognized risk factors are age older than 35 years and preoperative best corrected visual acuity greater than 20/25.

Surgeon discourages combining DMEK with phaco

WARSAW — Phakic eyes fare better than pseudophakic eyes after Descemet’s membrane endothelial keratoplasty, and given the low incidence of induced cataract development, there is no reason to combine DMEK with phaco, according to one surgeon. Fearing that endothelial grafts may be damaged by postoperative cataract development and subsequent phaco surgery, surgeons sometimes choose to combine the two procedures, Jack Parker, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Dual-optic accommodating IOL may offer premium technology without halo, glare

WARSAW, Poland — A dual-optic accommodating IOL may be the best option for many patients who ask to be treated with premium procedures and technologies, according to one surgeon.“Some patients come to my office and tell me that they want a premium technology but don’t want the problems their friends are experiencing, namely halos and glare. These are the perfect candidates for the [Abbott Medical Optics] Synchrony lens. I explain to them that they are likely to need some add for reading books, but computer vision will be perfect,” Matteo (Read more...)

Useful vision restored in retinitis pigmentosa patients who received subretinal implant

More than half of patients with severe retinitis pigmentosa who received the Alpha IMS subretinal implant recovered functional vision, according to results from a second human clinical trial of the device. The trial examined nine patients for a 3- to 9-month period after subretinal implantation of the Alpha IMS (Retina Implant), a 3 mm × 3 mm, 1,500-pixel device designed to restore vision without externally visible equipment.

New aberration-optimized algorithm leads to good results in hyperopic patients

WARSAW, Poland — A new aberration-optimized SupraCor algorithm leads to good results in hyperopic patients, according to one surgeon. A prospective study of 46 patients with refraction between +0.5 D and +4 D and astigmatism up to 3 D was presented at the winter meeting of the European Society of Cataract and Refractive Surgeons. A near addition of +2 D or more was needed. Patients underwent LASIK with the Femto LDV Crystal line (Ziemer) for flap creation. “In the hyperopic patient, you initially perform the correction for far, and in (Read more...)

Study: Low-price strategy in refractive surgery has no benefits, large profit losses

WARSAW, Poland — A low-price strategy in refractive surgery leads to no benefits and large profit losses for health care providers, according to a study carried out at the Bellevue Eye Clinic in Kiel, Germany. “We found that the level of price sensitivity is low amongst candidates for refractive surgery. About 12% of LASIK patients and 20% of refractive lens patients paid less than patient-related maximum willingness to pay,” Tim Herbst, project manager, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

AS-OCT facilitates decision making regarding surgical re-intervention after DMEK

WARSAW, Poland — Anterior segment optical coherence tomography showed high predictive value in evaluating graft adherence status and may facilitate decision making regarding surgical re-intervention after Descemet’s membrane endothelial keratoplasty.“Graft detachment is the most frequent complication in endothelial keratoplasty, occurring in about 10% of our cases at the NIIOS clinic in Rotterdam,” Marina Rodríguez Calvo de Mora, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Enhanced surgical technique optimizes safety and efficacy of corneal inlay

WARSAW, Poland — A new surgical technique for insertion of the Icolens corneal inlay proved safe and effective in a series of patients, according to one speaker.“The procedure is performed under topical anesthesia and involves two stages. Stage one is creation of the corneal pocket using the Femto LDV laser (Ziemer Ophthalmics), and stage two involves insertion of the hydrogel inlay using a unique preloaded deployment device,” Sarah Moran, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
