Chromatic and Monochromatic Optical Aberrations After Corneal Refractive Surgery

Refractive Errors Clinical Trial

Official title:
Chromatic and Monochromatic Optical Aberrations After Corneal Refractive Surgery - Preliminary Study Assessing Their Prevalence, Methods of Reductions of Symptoms and Time-dependent Changes in Patients Symptoms

Clinical Trial Summary

Refractive surgeries can be divided into two distinct categories: 1) corneal surgeries (superficial and deep procedures) carried on the surface of the eye and 2) lens surgeries (phakic IOL, refractive lens exchange) - an intraocular intervention, performed in the anterior or posterior chamber or on the lens. In the proposed protocol focus is on the corneal refractive surgeries impact on monochromatic higher-order aberrations on the one hand and chromatic aberrations on the other. During the surgery in order to get the patient emmetropic, refractive surgery corrects optical defects by decreasing aberrations of lower orders ) simultaneously increases high-order aberrations (that is perceived by the patient as halo, glare or starburst). Informations about prevalence and causes of higher order aberrations after refractive surgery are numerous but there is no information about chromatic aberrations.
