Cataract & Refractive

A Czech study has found that 2.2 mm square clear corneal incisions for microcoaxial phacoemulsification are very stable and provide adequate postoperative sealing.

Nowadays, cataract surgery not only has a therapeutic purpose, which is to substitute an opaque lens with a transparent IOL, but it also has a refractive aim; to correct previous refractive defects in order to eliminate the use of spectacles. The need for a good postoperative visual acuity and a fast functional recovery has lead cataract surgery to become more and more micro-invasive in nature so that surgical trauma is reduced, a faster recovery and good, time-stable visual results are achieved.1 The achievement of this goal has been realized, thanks to the improvement of surgical techniques, in the form of microcoaxial phacoemulsification and bimanual microphacoemulsification,2 which now allow the almost complete reduction of surgically induced astigmatism.

I have been so impressed with the aspheric optics and good centration of the Akreos MI60 that I use it as my first choice for implantation; including in patients with visual-critical occupations such as aviators and air traffic controllers

The new Custom Control Software on the MICS Millennium platform (Bausch & Lomb) results in less endothelial cell loss than torsional phacoemulsification performed on the Infiniti System (Alcon), according to a Greek study.

Microincision cataract surgery (MICS) with implantation of an aspheric intraocular lens (IOL) through a 1.8 mm incision can minimize surgically-induced corneal and ocular aberrations and improve optical performance, according to a French study.

Results of the European Society of Cataract and Refractive Surgeons (ESCRS) study of endophthalmitis prophylaxis do not appear to have had a significant impact on the practices of US cataract surgeons, according to the findings of an online survey conducted by the American Society of Cataract and Refractive Surgery (ASCRS) Cataract Clinical Committee.1 The survey results were reported by David F. Chang, MD, at the Spotlight on Cataracts 2007 symposium held during the annual meeting of the American Academy of Ophthalmology.

During accommodation, changes in lens thickness are mainly caused by deformation of the nucleus. In older, non-accommodating lenses, the deformations occur predominantly in the equatorial region and do not affect the central curvatures of the lens, according to a report published online ahead of print by Acta Ophthalmologica.

There have always been good arguments for surface ablation, but in most cases I have personally preferred LASIK. Yet every year I find myself performing more and more surface ablation cases and I am not alone in this.

The AcuFocus ACI 7000 corneal inlay could become a new, minimally invasive option for treating patients with presbyopia, Dr Günther Grabner announced at this year's Alicante Refractiva International meeting.

Intracameral cefuroxime is a safe alternative to subconjunctival cefuroxime and leads to a lower rate of endophthalmitis, claims a study published in the March 2008 issue of the Journal of Cataract & Refractive Surgery.

Compensation of cyclotorsion using iris registration can be helpful in decreasing misalignment of the axis of correction and in improving the overall outcome of LASIK, according to a study to be published in the April 2008 issue of the Journal of Cataract & Refractive Surgery.

Look at some of the Phakic IOLs that have been making a name for themselves in Europe.

Accommodating IOLs are making a splash in Europe - why don't you take a closer look at some of them?

Intraocular lenses (IOL) made from polymethylmethacrylate (PMMA) may be associated with an increased risk of postoperative endophthalmitis.

The first results of an ongoing multicentre study in France suggest that a new diffractive intraocular lens (IOL), Diffractiva-s (HumanOptics), offers good visual results.

Cataract referrals made by optometrists are more likely to include better information regarding vision loss than referrals made by general practitioners .

Preoperative tear volume may affect recovery of the ocular surface after LASIK and could increase the risk for chronic dry eye.

Topical levofloxacin penetrates better than ofloxcin or ciprofloxacin into the aqueous of eyes with functioning filtering blebs.

Six-month data for myopia treatments with the SCHWIND AMARIS laser show that it is effective and patient friendly.

Bausch & Lomb has acquired eyeonics, the maker of the crystalens accommodating IOL.

Diffuse lamellar keratitis (DLK) occurs more frequently after LASIK performed with the IntraLase 15 kHz femtosecond laser than after LASIK performed with the Moria M2 microkeratome.

Female cataract surgery patients are more likely to assess their postoperative visual function as worse than male patients.

The M2 microkeratome (Moria), the Carriazo-Pendular microkeratome (Schwind) and the IntraLase femtosecond laser all create flaps of predictable thickness.

Incision sizes needed to remove cataracts have been significantly reduced by new technology, such as the vision enhancement system (Stellaris; Bausch & Lomb) which allows surgeons to make two 1.8 mm cuts on either side of the eye.

A study published in the January issue of Antimicrobial Agents & Chemotherapy, has found that the high proportion of corneal infections linked to contact lens solutions are fuelled and made resistant to treatment by the formation of a highly resistant structure of microbial cells held together with a glue-like matrix material, called biofilms.

The use of glaucoma drainage surgery is decreasing in Britain, which may be explained by an increase in cataract extraction, according to a report published in the January issue of Eye.

Using a telemedicine system to assist ophthalmologists in developing countries with the diagnosis and management of various ophthalmic conditions can be successful.

Wavefront-guided LASIK is a safe and efficacious way to correct moderate to high myopia and compound myopic astigmatism.
