[From scattering to wavefront. Healing optics]

Area of Science:

• Ophthalmology
• Optical Engineering
• Biomedical Optics

Background:

• Refractive laser surgery aims to correct vision by altering corneal shape.
• Complicated refractive procedures can lead to unforeseen optical effects.
• Understanding surface irregularities is crucial for predicting post-operative outcomes.

Purpose of the Study:

• To discuss the optical effects of irregular surface structures after refractive surgery.
• To investigate aberrations beyond classical scattering and higher-order wavefront errors.
• To evaluate the impact of corneal irregularities on retinal image quality.

Main Methods:

• Analysis of optical effects stemming from irregular surface structures.
• Focus on the range between scattering and higher-order wavefront aberrations.
• Case study demonstrating induced optical aberrations post-refractive surgery.

Main Results:

• Corneal surface irregularities can induce significant optical aberrations distinct from classical errors.
• Current commercial wavefront sensors may not accurately measure these novel optical errors.
• The study highlights the need for advanced measurement techniques.

Conclusions:

• Surface irregularities present a unique challenge in refractive surgery outcomes.
• Novel optical aberrations require specialized detection methods.
• The healing process's influence on the Strehl ratio warrants further investigation.
