We evaluated the visual, refractive and ocular aberrometric outcomes after wavefront-guided (WFG) laser in situ keratomileusis (LASIK) for the correction of myopia using an excimer laser platform with Iris Registration (IR) technology (STAR S4IR excimer laser, Abbott Medical Optics, Santa Ana, CA, USA) and combined with a new Hartmann-Shack wavefront sensor (iDesign aberrometer, Abbott Medical Optics, Santa Ana, CA, USA) capturing 1250 data points from a 7.0-mm pupil and using Fourier reconstruction for aberration data.
It’s a way of measuring the eye before treating it to get rid of any spectacle error present. Because it uses more ‘data points’ than older instruments, it gives a more accurate assessment of the eye in planning for it to be able to see without the need for contact lenses or glasses.
There are several common eye diseases in all age groups, below are some of the most common eye problems: In children: blocked tear ducts, turn in the eyes (crossed eyes) and conjunctivitis. In young adults: allergic eye disease, conjunctivitis, chalazions.
