Corneal Refractive Therapy Design Comparison for -4 to -6 Diopter Treatment for Overnight Wear for Myopia

Myopia Clinical Trial

Official title: A Prospective Study to Compare Lenses Having Two Different Proximity Control Designs for Overnight Wear for Treatment of Naturally Occurring Myopia From -4 to -6 Diopters Sphere With Refractive Astigmatism up to -1.75 Diopters

Status Completed

Clinical Trial Summary

The primary objective of this study is to compare the effectiveness of two proximity control geometry lens designs to treat eyes with pretreatment myopia between -4.00 and -6.00 D myopia with and without refractive astigmatism in a modality involving overnight wearing.

Clinical Trial Description

Each subject shall undergo a comprehensive eye examination to determine eligibility. Subjects must meet all eligibility criteria. All eyes shall be treated with two pair of the proximity control lenses by the qualified clinical investigator. The first pair shall be dispensed and scheduled follow-up examinations shall be conducted at one day, one week, and two weeks after dispensing lenses. Each subject shall then cease wearing lenses for at least 7 days and be re-examined to determine that the corneal curvature has returned to its baseline measure. The second design shall be dispensed and scheduled follow-up examinations shall be conducted at one day, one week, and two weeks after dispensing lenses. Each subject shall then cease wearing lenses for at least 7 days and be re-examined to determine that the corneal curvature has returned to its baseline measure. ;
