Abstract Details

Purpose:

This study was conducted to describe the safety and efficacy of overnight orthokeratology among myopic patients in Taiwan.

Setting:

This prospective case series study was conducted in two medical centers in Taiwan.

Methods:

Seventy-seven subjects (ages 12 to 54) were enrolled in the 10-month pilot study. Uncorrected visual acuity (UCVA), refractive error, corneal topography, biomicroscopic data, intraocular pressure, and endothelial cell density were collected to determine the efficacy, and a safety profile of overnight orthokeratology.

Results:

Sixty-eight subjects (ages 12 to 54) completed the study. The mean baseline manifest refraction spherical equivalent (MRSE) was between -1D to -4D. The UCVA (Snellen chart) were better than 0.8 in 100% of patients, and better than 1.0 in 98.51% of patients at 9 months. No significant change in UCVA, MRSE and corneal curvature was noted one month after discontinuation of orthokeratology, compared with baseline data. No serious adverse events occurred during the study.

Conclusions:

The results indiacated that short-term correction of mild to moderate myopia with overnight orthokeratology is safe and efficacious in myopic patients. FINANCIAL INTEREST: NONE
