"A series of small studies conducted in the United States and Canada found that most patients who underwent laser presbyopia reversal (LAPR) had significant clinical improvement and could read magazines and newspapers without glasses shortly after surgery. Scleral ablation was performed with the OptiVision laser treatment system
"(SurgiLight Inc.). Using an infrared laser with a 3-µm wavelength, the surgeon makes eight external incisions in the sclera to increase the efficiency of the ciliary muscle. This results in a stronger capacity of the eye to focus on near objects, said Sandra Belmont, MD, principal investigator and associate professor of clinical ophthalmology at Weill Cornell Medical College, New York.
"In studies conducted at Weill Cornell and at the Las Vegas clinic of Jon Siems, MD, all 10 patients were able to read a newspaper without glasses within 1 or 2 weeks of surgery, and six of 10 showed successful accommodation, an increase of 1 to 3 D." http://www.surgilight.com/OT12-19-03e.pdf
