Oct. 26, 2009 (PR Newswire) --

MONROVIA, Calif., Oct. 26 /PRNewswire-FirstCall/ -- STAAR Surgical Company (Nasdaq: STAA), a leading developer, manufacturer and marketer of minimally invasive ophthalmic products today reported that the Collamer Accommodating Study Team (CAST) formed by the company in late 2008 has provided very promising initial patient vision assessments from the first phase of the project. The CAST is comprised of eight prominent cataract/refractive surgeons from across the United States who since June 2009 have implanted more than 300 eyes with the STAAR nanoFLEX intraocular lens (IOL) for the treatment of cataracts.

The purpose of the CAST first phase is to evaluate the accommodating properties of the current nanoFLEX IOL to establish a baseline for future phases. Accommodating IOLs are designed to allow patients to see well at all distances, including enabling the patient to experience improved near and intermediate vision, thus reducing or eliminating the effects of presbyopia. Presbyopia is the loss of the ability to focus on objects at near and intermediate distances and is caused by the loss of elasticity of the crystalline lens after the age 45. Presbyopia is typically corrected with the use of reading glasses or corrective lenses. With standard IOLs cataract patients frequently find a need for reading glasses particularly in low light environments. Near vision is the vision needed to read a book or a menu in dim light. Near vision testing is typically performed at a distance of approximately 40cm or 15.75 inches, while intermediate vision, the vision needed to work on a computer or view the dashboard of a car is approximately 80cm or 31.5 inches.

Of the more than 300 eyes implanted, up to four months of follow up has been assessed on 73 binocular near vision patients (146 eyes) and 59 binocular intermediate vision patients (118 eyes). Based on the preliminary assessment, the outcomes indicate that nanoFLEX provides superior distance-corrected near vision compared with the leading standard IOLs and comparable results to current premium IOLs. In addition, the outcomes indicate that nanoFLEX provides superior distance-corrected intermediate vision to any IOL compared - including premium IOLs. The collective data from the CAST was presented October 24th during the American Academy of Ophthalmology (AAO) by Dr. James Lewis from Philadelphia, Pennsylvania. Craig Felberg, Vice President of Research and Development, STAAR Surgical, presented longer term patient data on the accommodative properties of the Collamer material which was collected by Dr. Liviu Saimovici of New York City. Mr. Felberg also reviewed the plans for the CAST Second Phase.

"The CAST assessment of the baseline accommodating properties of the new Collamer nanoFLEX IOL is quite encouraging and better than we expected when this evaluation began," said Barry G. Caldwell, President and CEO of STAAR Surgical. "Our product development team is engineering minor design changes to the nanoFLEX for the purpose of a Second Phase which will include a clinical study by CAST members to determine whether these minor design changes can improve upon current results. We very much appreciate the work by the CAST members and in particular the leadership of Dr.
