An ambitious French study has been launched with the goal of determining the clinical and medico-economic benefit of femtosecond laser-assisted cataract surgery, according to Cedric Schweitzer MD. Addressing delegates attending the annual meeting of the French Implant and Refractive Surgery Association (SAFIR), Dr Schweitzer said the FEMCAT* study represented an important and necessary effort to establish some scientific basis for the theoretical benefits of femto-cataract surgery.

As technologies evolve and national health systems become increasingly conscious of the need to reduce costs, there is perhaps a real rationale in redefining the current definition of cataract to enable greater account to be taken of quality of vision in its definition and diagnosis, according to Beatrice Cochener MD, PHD.

Endothelial cell loss and cataract were the two most common reasons for the removal of phakic IOLs cited in a long-term French study presented at the annual meeting of the French Implant and Refractive Surgery Association (SAFIR). In a retrospective review of 10 years of phakic IOL explantations carried out at the University Hospital, Toulouse, Pierre Fournié MD reported that 129 phakic implants in total were explanted between 2003 and 2012.

With multifocal intraocular lens near vision adds ranging from +2.5 to +4.0 D now available, the question arises: how much is enough? The answer depends on several factors, including reading habits and even language, Hiroko Bissen-Miyajima MD, Tokyo, Japan, told the American Society of Cataract and Refractive Surgery Symposium. She suggests reading the literature first, but listening to patients is critical to sorting out which lens is best for whom.

Different power, different vision

The LenSx® (Alcon) femtosecond laser system is highly flexible in the performance of cataract surgery and may provide some important safety advantages over conventional ultrasound phacoemulsification, said Prof Jacek P Szaflik MD, PhD, Medical University of Warsaw, Poland.

A device capable of accurately measuring epithelial thickness may prove beneficial in the planning of corneal refractive surgery as well as being a potentially useful tool in screening for suspect keratoconus, according to Georges Baikoff MD.

 

 
Surgeons have two methods for correcting pre-existing corneal astigmatism during cataract surgery: We can perform arcuate incisions (typically limbal relaxing incisions or some modification of LRIs) or we can implant a toric IOL.

New generation of accommodating IOLs offers objective forward movement and significant pseudoaccommodative effect
