Summary

This trial will compare how comfortable Euclid orthokeratology lenses are with and without a special coating in 50 children. They will also track how much the children's eyes grow in size over time.

Who is the study for?
This trial is for children who are near-sighted and have healthy corneas. They must be willing to wear orthokeratology lenses and participate in regular check-ups to monitor the length of their eyes.
What is being tested?
The study compares two types of Euclid orthokeratology lenses: one with an enhanced coating and another with a standard coating, focusing on lens comfort and effectiveness in slowing down eye growth.
What are the potential side effects?
Potential side effects may include discomfort while wearing the lenses, temporary visual disturbances, or minor eye irritation due to the coatings.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Euclid orthokeartology (standard coating)Experimental Treatment1 Intervention
Euclid Orthokeratology Contact Lenses are lathe cut contact lenses with spherical posterior surfaces. The posterior curve is selected to properly fit an individual eye for orthokeratology and the anterior curve is selected to provide the necessary optical power for a temporary reduction of myopia. A peripheral curve system on the posterior surface allows tear exchange between the lens and the cornea.
Group II: Euclid orthokeartology (enhanced coating)Experimental Treatment1 Intervention

The posterior curve is selected to properly fit an individual eye for orthokeratology and the anterior curve is selected to provide the necessary optical power for a temporary reduction of myopia.
