The ability to see is dependent on the actions of several components in and around the eye.
When looking at an object, light rays are reflected from the object to the cornea. The lights rays are refracted and focused by the cornea and the lens. The lens allows the light rays to focus sharply on the retina, and results as an upside-down image. The retina then converts the light rays into electrical impulses which are transmitted through the optic nerve to the brain. The brain translates the image and the result is an image in the upright position.
The human eye is similar to a camera. A camera needs a lens to focus an image and film to produce an image. In that way, the eye needs a lens (cornea, lens) to refract and focus light and a film (retina) on which to focus the light rays. If any one or more of these components is not functions properly, the result is a poor image. The retina, representing the film in a camera, captures the image and sends the picture to the brain to be developed. The macula is the highly sensitive central area of our retina that is responsible for our central focusing vision. It is the most used part of the retina
MYOPIA: Nearsightedness
Myopia, also known as nearsightedness is when the light entering the eye focuses in front of the retina rather than on the retina. Nearsighted people typically see well up close but poorly at a distance. This is caused by the eye being longer than a normal eye.
HYPEROPIA: Farsightedness
Hyperopia, also known as farsightedness, is when the light entering the eye focuses behind the retina rather than on the retina. Farsighted people typically have difficulty seeing up close and at a distance. This is caused by the eye being shorter than a normal eye.
ASTIGMATISM:
Astigmatism is when the front surface of the eye called the cornea is oval like a football rather than spherical like basketball. The cornea has 2 points of focus, a steeper point and a flatter point that causes light to focus at one or more points onto the retina, resulting in blurry vision for distance and near.
M. K. Gupta, M.D. is the Medical Director of Sugarbush Eye & Laser Centres. Dr. Gupta's extensive training in ophthalmology includes medical school and a four-year ophthalmology residency. He then completed four more years of training including a neurology residency, an ocular motility fellowship, and a cornea fellowship. In Dr. Gupta's undergrad training, he received the Presidents Award for Academic excellence.
Dr. Gupta takes pride in keeping up-to-date with the latest technology and techniques through regular attendance at international ophthalmology conferences.
In addition to his training as an ophthalmologist, Dr. Gupta received his post-doctoral fellowship training from the State University of New York in 1976.
He has studied under world-renowned eye surgeons such as Dr. Jose Barraguer, inventor of LASIK, and Dr. Louis Ruiz, inventor of the Microkeratome, the instrument used to make the corneal flap during the LASIK procedure.
Dr. Gupta opened his practice in Ashland in 1977, and added the Mansfield location in 1998. He is on the medical staffs of several hospitals including Ashland Samaritan, Akron General Medical Center, Galion Community Hospital, MedCentral in Mansfield, and is an affiliate of the Cleveland Clinic Foundation. Dr. Gupta is a well-known and frequent speaker at international meetings and symposiums of eye surgeons.
Dr. Gupta has participated in numerous medical mission trips to third-world countries, performing thousands of sight-saving eye surgeries at no cost. He has also provided free care to qualifying underprivileged patients in the central Ohio area who were unable to afford eye care.
