As levels of myopia continue to rise to epidemic proportions in China and other parts of East and Southeast Asia, there is growing evidence that education and behaviour may have a greater impact on the development of near-sightedness than do genetic factors.
With each school year completed a person becomes more near-sighted, and the higher the level of education completed, the more severe the impairment of vision, according to the results of a major population-based cohort study of myopia carried out at Mainz University Medical Centre, Germany.

The cerebrospinal fluid (CSF) pressure is a potentially critical parameter in the pathology of primary open-angle glaucoma, a finding with possible implications for research, reports Jost B Jonas MD, University Eye Clinic, Mannheim, Germany. 
“Physiological relations in the dynamics of the change in intraocular pressure (IOP) and orbital cerebrospinal fluid pressure may play a role in the onset and progression of glaucomatous optic neuropathy,” he told the 11th Congress of the European Glaucoma Society in Nice.

When Google and Novartis announced a partnership earlier this year to develop a range of smart contact lenses to improve vision and monitor health, the widespread media coverage was predictably upbeat. 
“Sweet solution for diabetics”, “Smart contact lens promises to revolutionise diabetes treatment” and “Smart lenses eyed as medical breakthrough” were just three typical headlines welcoming the announcement.

Minimising energy dissipated in the eye during cataract surgery, whether ultrasonic or laser, may lower the risk of damaging delicate intraocular tissues. But while current phaco systems allow continuous ultrasonic energy control during surgery, femtosecond (FS) laser systems do not.
However, total laser energy delivered during FS laser-assisted cataract surgery can be reduced by lowering the pre-set power of individual laser pulses, Roberto Bellucci MD, Verona, Italy, told the 2014 ESCRS Congress in London. 

Corneal stromal stem cells can now be isolated reliably from long-term stored organ culture corneas, opening up the possibility to develop cell- and tissue-based therapies for a wide range of corneal diseases, according to Alvena Kureshi PhD.

Serefeddin Sabuncuoğlu (1385-1468), who lived in the city of Amasya in central Anatolia, wrote the first illustrated surgical textbook in Turkish-Islamic medical literature, namely Cerrahiyyetü’l-Haniyye (Imperial Surgery), in 1465. 

Endothelial cell loss is an important outcome parameter for corneal transplantation procedures as it is used both as a measure of success and for predicting survival of the transplanted tissue. However, interpretations of data on endothelial cell loss following different keratoplasty techniques should consider that there are a number of limitations affecting the accuracy of the determinations, according to Isabel Dapena MD, PhD.

... The emulsification was done in the anterior chamber. Healon is shown to have a protective effect on the cornea as judged by corneal thickness measurements and by endothelial cell counts. … [N]o attempt was made to remove Healon from anterior chamber at the end of surgery. It cannot be excluded that Healon may occasionally cause increased intraocular pressure...”– Holmberg AS, Philipson BT. Ophthalmology. 1984 Jan;91(1):53-9.
