Nine myopic subjects (eighteen eyes) were fit with Hydrocurve II soft lenses for three months, then fit with Permaflex soft lenses for three months, both on an extended wear basis. During this time one patient developed corneal microcysts, one developed early signs of neovascularization, two could be fit with only one pair of lenses and another could not adapt to either set of lenses.

By a careful process of preselection, the percentage of successful extended wear patients was increased over the studies of the previous two years which utilized similar lenses. Choosing previous successful daily soft lens wearers with good hygiene and compliance may help avoid previously described problems.
