After bilateral cataract surgery, patients implanted with multifocal lenses were more likely to be spectacle-independent but also to undergo intraocular lens exchange than those with monofocal lenses. Medscape Medical News
Dry eye disease symptom change independent of tear osmolarity
Tear osmolarity is a poor indicator of treatment response in patients with dry eye disease (DED), suggests research published in the American Journal of Ophthalmology.

DMEK leads to mild hyperopic shift, long-term refractive stability
AMSTERDAM — Corneal deturgescence following Descemet’s membrane endothelial keratoplasty leads to a mild hyperopic shift, probably caused by changes in the posterior surface of the cornea. “After these minor changes, refraction remains stable in the long term,” Marina Rodriguez, MD, said at the European Society of Cataract and Refractive Surgeons meeting.

New MICS intraocular lens performs well in a multicenter study
AMSTERDAM — Micro-incision cataract surgery with implantation of the Incise IOL produced good, stable refractive outcomes with low deviation from target refraction, according to a study.The Incise IOL (Bausch+Lomb) is made of hydrophilic acrylic material with a 22% water content. It is an aberration-free aspheric design with a 6mm optic and a power range from 0D to 30D in 0.5D increments. The 360° sharp posterior optic edge has been optimized for effective posterior capsule opacification (PCO) prevention.

Endothelial cell loss following DMEK may be overestimated by standard calculation methods
AMSTERDAM — The amount of endothelial cell loss following Descemet membrane endothelial keratoplasty may be overestimated by the standard methods of measuring cell density, according to one speaker here at the European Society of Cataract and Refractive Surgeons meeting. The decline in endothelial cell density (ECD) after DMEK has been quantified as a reproducible 34% in the first 6 months due to the traumatic insertion of the graft during the operation, followed by a stable rate of 7% per year.

Tear film osmolarity a critical parameter in diagnosis of dry eye
AMSTERDAM — Tear film osmolarity is a critical parameter in determining what specific form of dry eye affects the patient and what treatment should be employed, according to one specialist.Mitchell A. Jackson, MD, reminded the audience at the European Society of Cataract and Refractive Surgeons meeting that the Dry Eye Workshop updated definition of dry eye included “increased osmolarity of the tear film” as a key factor. And yet the Consensus Guidelines based on classification levels 1 to 4 do not include osmolarity among signs.
