The process of vision begins when light rays that reflect off objects and travel through the
eye's optical system are refracted and focused into a point of sharp focus on the retina.
Nearsightedness (Myopia)
Close objects are clear far-away objects look blurry
Often discovered in childhood and progresses throughout the teenage years
Farsightedness (Hyperopia)
Close objects are more blurry than distant objects.
In mild hyperopia, distance vision is clear while near vision is blurry.
In advanced hyperopia, vision can be blurred at all distances.
LASIK Surgery
LASIK (or Laser-Assisted In-Situ Keratomileusis) is the most modern surgical procedure for correcting vision problems like myopia, hyperopia, and astigmatism. This is an advanced laser vision correction technique in which the curvature of the cornea is reshaped using a laser that is capable of removing tissues with precision up to a micron level. For this procedure patients should be at least 18 years of age and the refraction (spectacles power) should be stable (unchanged) for at least a year. Persons who typically opt for LASIK are those who find spectacles visually unacceptable, those who are intolerant to lenses, those who would like to participate in outdoor sports or opt for professions demanding excellent uncorrected vision.
However, though doctors strive to make the refractive error zero after LASIK, this may not always be possible. The main purpose of surgery is to offer sufficient good vision to patients so that they are not dependent upon glasses most of the time. Some of the possible side effects of LASIK are undercorrection, overcorrection, glare, halos, and reduced contrast sensitivity. Therefore patients must have a detailed eye examination before surgery, followed by a realistic discussion with the surgeon on the expected outcome of surgery.
ICL Surgery
Visian ICL (also known as an Implantable Collamer® Lens) is inserted just behind the iris, between the eye’s natural lens and colored iris. The intent of this procedure is to modify the eye’s focusing power and reduce the need for eyeglasses or contact lenses. An ICL procedure is commonly utilized to treat moderate to severe myopia (nearsightedness) and/or astigmatism.
ICLs complement the eye’s existing lens to bend (refract) light on the retina, resulting in improved vision correction. The ICL is composed of plastic and purified collagen (which also naturally occurs in your body). This implant is biocompatible, soft, and flexible, and provides ultraviolet light protection as well. You may occasionally hear ICLs referred to as an “implantable contact lens” or “permanent contact lenses” as it has a similar function to that of a traditional contact lens.
