Is autoimmunity in primary antibody deficiency associated with protein tyrosine phosphatase nonreceptor type 22 ( PTPN22 )?
The 1858T PTPN22 allele is strongly associated with autoimmunity in patients with PAD.
The KPro's wide depth-of-focus makes the visual acuity less dependent on an exact refractive correction at distance and explains the 'pseudoaccomodation' experienced by these patients. This is primarily due to the small pupil diameter of the KPro. The current manufacturing steps in 0.50 dioptre increments appears to be sufficient.
