Extended wear of Hydrocurve II55 soft contact lenses.

Nine myopic subjects (eighteen eyes) were fit with Hydrocurve II55 soft lenses and completed an average of seven months of extended wear with comfort and no significant side effects. Significant changes included horizontal meridian subjective refraction (myopia increased 0.26 D), PEK horizontal central power (0.23 D steepening), and PEK horizontal shape factor (increased .10). Papillary hypertrophy increased in 14 of 18 eyes but no subject had a giant papillary response. Conjunctival sample showed an increase in cellular infiltrates. Corneal aesthesiometry showed a significant increase in sensitivity. A safe, effective regimen for extended wear with normal myopic eyes was developed. Fitting and follow-up recommendations were made.
