Is ‘Internal Astigmatism’ Compensation or Constant? The researchers analyzed follow-up data on 367 individuals with myopia. Over a 14-year period, the subjects underwent detailed measurement of eye structures as well as assessment of refractive (focusing) error. The findings were compared to one-time measurements in a matched group of 204 subjects without myopia. The goal was to assess changes in the “internal astigmatism” of the eye over time. “Clarity of vision is determined by the precise shape of the eye and coordination of several optical components that must all be perfectly balanced to provide proper focus,” explains Michael Twa, OD, PhD, Editor-in-Chief of Optometry and Vision Science.
