What this trial studies

This study investigates how two types of bandage contact lenses, with different base curves, affect visual recovery and pain levels in patients who have undergone Trans-PRK surgery for high myopia. By comparing the outcomes in the same individual using lenses with base curves of 8.4 mm and 8.8 mm on contralateral eyes, the study aims to determine the optimal lens choice for post-operative care. The methodology involves a single-step Trans-PRK procedure followed by the application of the respective contact lenses. This approach allows for a controlled comparison of the effects on vision and comfort.

Who should consider this trial

Good fit: Ideal candidates are individuals with high myopia and steep corneas, specifically those with a spherical equivalent refractive error between -6.00 and -8.00 D.

Not a fit: Patients with systemic diseases, ocular diseases, or those who do not meet the specific refractive criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved visual recovery and reduced pain for patients undergoing Trans-PRK surgery.

How similar studies have performed: While the specific comparison of these two base curves in bandage contact lenses is novel, similar studies have shown that optimal lens selection can significantly impact recovery outcomes.
