The correction of presbyopia: A prospective study

A prospective office-based study was undertaken to evaluate the rate of suc cess of single-vision, bifocal trifocal, and progressive lenses to correct presbyopia. Results suggest that successful presbyopia correction varies wi th individual patient characteristics. Approximately one-third of the study subjects opted for progressive lens correction, one-third for conventional segmented bifocals, and one-third for single-vision lenses. Involving each patient in the nuances of the lens selection process is critical to accura te presbyopic fit.
