ABSTRACT
The aim was to analyze the changes in centralcorneal thickness values due to soft contact lens wear. We analyzed the central corneal thickness values (baseline measurements) of 15 myopic adolescent soft contact lens wearers (15 eyes; aged 15 to 16 years old). Three years later, the central corneal thickness wasmeasured again. We also measured the central corneal thickness of 31 myopic adolescents who did not use contact lenses (31 eyes; aged 15 to 16 years old) and 34 myopic contact lens wearers aged between 25 and 40 yearsold (34 eyes). We obtained the mean of fivemeasurements using the Orbscan Topography System II (Orbscan, Inc., Salt Lake City, UT,USA). In the later measurements (three years)there was a significant decrease in the central corneal thickness values (p=0.012) of the adolescent contact lens wearers and the contact lens subjects aged 25 to 40 years old(p<0.001). This decrease was not found in theadolescent non-contact lens wearers (p=0.476). The central corneal thickness values of the adolescent contact lens wearers were significantly lower than the baseline values up to four weeks after removal of theircontact lenses (p=0.201). In conclusion, therewas a significant reduction in the anatomic values of corneal thickness associated with soft contact lens wearers, although baseline thickness values recovered to normal levels approximately one month after the use of contact lenses had ceased (AU)
