Corneal Response to Thick and Thin Hydrophilic Lenses

Key Points

This research aims to compare the effects of thick and thin hydrophilic lenses on corneal sensitivity and thickness over six months.
Participants wore thick and thin hydrophilic lenses for six months.
Measurements of corneal sensitivity and thickness were taken at regular intervals.
Changes in corneal power were analyzed for both lens types.
Thick lenses caused greater changes in corneal sensitivity and thickness compared to thin lenses.
Chronic edema levels of 3-4% were observed with thick lenses.
No significant changes in corneal power were noted for either lens type.

Abstract

Abstract Thick and thin hydrophilic lenses with otherwise similar parameters were worn by patients for a period of 6 months. The thicker lenses produced greater changes in corneal sensitivity and thickness during the course of adaptation and wear than did the thinner lenses. Chronic edema levels of 3–4% were noted with the thick lenses. Changes in corneal power for each lens group were not significant. Thin hydrophilic lenses seemed to produce less upset of normal corneal physiology over the course of the 6‐month wearing period.
