PiXL for Correction of Hyperopia

Photorefractive Intrastromal Corneal Crosslinking (PiXL) for Correction of Hyperopia

This clinical study aims to investigate the efficacy and safety of PiXL in the refractive correction of low hyperopia.

This clinical study aims to investigate the efficacy and safety of PiXL in the refractive correction of low hyperopia.Slightly modified settings from previously published study is applied to eyes with low hyperopia with an expected refractive change of 0.75 D. Aim is to evaluate the refractive outcome of this procedure.

Inclusion Criteria:

• low hyperopia of spherical equivalent from +0.5 up to +1.75 D sp. eq.
• astigmatism up to 0.75 Dcyl
• corneal thickness above 400 µm
• endothelial cell density above 1500 cell/mm2

Exclusion Criteria:

• any prior corneal surgery or any eye surgery within the last 3 months,
• any corneal pathology e.g. corneal scar or dystrophy
• unstable refraction
• patient not able to understand and sign informed consent
• patients with connective tissue disorder or uncontrolled diabetes
• pregnant or lactating women
• aphakic eyes or pseudophakic eyes without UV blocking IOL
