Wavefront analysis represents a major advancement in the field of modern optometry and ophthalmology. It allows the identification and quantification of high-order optical aberrations that cannot be detected through conventional refraction methods. It plays a crucial role in visual quality assessment, guiding customized laser refractive surgeries, and optimizing the design of advanced contact lenses.<br /><br /> • The aberrometer device is used to capture and analyze the distortion of light waves as they pass through the eye’s optical system. The results are typically presented using Zernike polynomial maps, which graphically represent the eye’s optical imperfections.<br /> • High-order aberrations such as spherical aberration, coma, and trefoil are major contributors to poor visual quality, especially under low-light conditions, even after conventional correction with glasses.<br /> • Applications include:<br /> • Evaluation of night vision performance.<br /> • Customization of LASIK and PRK surgeries.<br /> • Development of tailor-made contact lenses.<br /> • Assessment of vision in athletes, drivers, and professionals in critical visual environments.<br /><br />Conclusion:<br /><br />Wavefront analysis is a cutting-edge diagnostic tool that enhances precision in visual correction and reduces refractive failure. Its integration into routine clinical practice empowers optometrists and ophthalmologists to offer truly personalized vision care.
