Vision Correction


Eyesight is a precious sense you should never overlook. When our vision is impaired, we often struggle with simple tasks necessary to lead a productive life. It is important we recognize not only the vision problems people face, but also the treatments that can prevent and correct them.

Common Vision Problems and Correction Options

One of the services that an ophthalmologist performs is the diagnosis and treatment of vision problems. When a person has problems seeing clearly, it often affects all aspects of their lives, from reading a computer screen to seeing road signs while driving. Not only can vision problems create frustration and embarrassment, but they can also be dangerous to both the individual with the problem and the people around them. For this reason, certain careers (such as an airplane pilot or a firefighter) require the participant to have 20/20 (or clear) vision.

According to the World Health Organization, approximately 285 million people worldwide have some type of visual impairment, 80 percent of which can be prevented or cured. A large portion of this number includes common vision problems which prescription lenses or a vision correction procedure can treat. The ophthalmologists included in our directory have a proven track record with both peers and patients, earning them a reputation as the most experienced and skilled eye doctors in their field of ophthalmology. Read on to learn more about the vision problems these eye doctors diagnose and the vision correction options they offer to their patients.

Common Vision Problems

Patients who have vision problems are those who have less than 20/20 vision in one or both eyes. They have what’s called a refractive error. A refractive error means the light entering the eye does not bend or refract correctly when it passes through the cornea and reaches the retina. A refractive error in one or both eyes is what causes vision problems, which are characterized by blurry near or distance vision, or both. The following vision conditions occur because of refractive errors:

  • Myopia
  • Hyperopia
  • Astigmatism
  • Presbyopia

Myopia (nearsightedness), is a refractive error which causes distant vision to be blurry or unclear. This error occurs because of the eye being too long, or the cornea overly curved which interferes with the cornea’s ability to refract light rays onto the retina. As a result, the eye is unable to focus and needs vision correction. People with myopia typically have vision problems like trouble seeing road signs, movie screens and other objects in the distance. A hereditary condition, myopia is usually apparent in childhood and will either remain unchanged or worsen with age.

Hyperopia (farsightedness)

Hyperopia, or farsightedness, is a refractive error which results in blurry near vision. The cause of these vision problems is either that the eye itself is too short, an irregularly shaped cornea or a combination of the two. One or both factors contribute to light rays focusing on a point behind the retina, instead of focusing on the retina itself, so images in the near distance appear blurry. People with hyperopia have problems with tasks which involve close-up vision, such as reading a book or a computer screen. Hyperopia is hereditary and is usually present at birth. Aging exacerbates hyperopia and will worsen your ability to focus.


Astigmatism is a refractive error which often occurs concurrently with hyperopia or myopia. This refractive error can experience vision problems with up-close vision, distance vision or both.

There are different types of astigmatism, including regular, irregular and mixed. Regular astigmatism occurs when the cornea is curved more in one direction than the other. Irregular astigmatism occurs when the cornea curves in multiple directions, instead of evenly across the surface of the eye. Mixed astigmatism occurs when the eye’s curvature causes one of its meridians (the vertical or horizontal half of the eye) to become hyperopic and the other myopic. The vision problems of astigmatism cause the surface of the cornea to have an irregular shape, preventing the light rays entering the eye from converging properly onto the retina.

Astigmatism is typically hereditary. Eye injuries, eye diseases or complications from eye surgery can also cause astigmatism.


Presbyopia, or age-related vision loss, often begins around the age of 40, causing a person to have difficulty reading and seeing things up-close. These vision problems are the result of the hardening of the eye lens, which gradually becomes thicker during the aging process. When the eye lens loses its elasticity and starts to harden, it can no longer change shape and focus properly. People with presbyopia will notice their near vision becomes increasingly blurred as they age. Most people with presbyopia need reading glasses to read or perform work tasks.

Diagnosing Vision Problems


Refractive errors and other vision problems are diagnosed through a comprehensive dilated eye exam performed by an eye care professional.

The eye exam consists of tests that measure eye health, visual acuity, how your eyes respond to light and how your eyes work together. These tests are used to diagnose refractive errors and determine an accurate prescription for corrective lenses.

Correcting Vision Problems

Once you determine vision problems are present, there are many ways (both temporary and long term) to correct them and achieve clearer vision. They include:

  • Corrective lenses
  • Refractive surgery
  • Lasik
  • Lasek
  • EpiLasik
  • Photorefractive keratectomy
  • Refractive lens exchange
  • Phakic intraocular lens implants
  • Intracorneal ring segments


Corrective lenses include prescription eyeglasses or contact lenses. Both types of corrective lenses are used to correct vision problems, including myopia, hyperopia, astigmatism and presbyopia.


Refractive surgery, or vision correction surgery, is used to correct common refractive error vision problems (including myopia, hyperopia, astigmatism, and presbyopia). Refractive surgery can reduce or eliminate dependence on glasses or contact lenses. The following are the most common refractive surgeries performed by ophthalmologists.

LASIK (laser in-situ keratomileusis) is the most commonly performed refractive surgery. The procedure involves creating a small incision in the cornea with a blade or a laser and then reshaping the cornea so it refracts light properly, resulting in clearer vision. LASIK surgery may also be used in tandem with wavefront technology, which uses computer imaging to provide precise measurements of the eye’s structure to guide the surgeon during surgery. This LASIK surgical method is often called “wavefront” or “custom” LASIK.

LASEK (laser epithelial keratomileusis) surgery involves lifting the outer layer of the cornea, using a fine blade along with an alcohol solution and then using a laser to reshape the cornea so that it refracts light properly.

EpiLasik is a procedure that involves separating a thin top layer from the cornea and then reshaping the cornea so that it refracts light correctly. A soft contact lens is temporarily used during the healing process.

PRK (Photorefractive keratectomy) is a laser eye surgery that reshapes the cornea by delivering a beam of ultraviolet laser light onto the surface of the cornea.

Refractive lens exchange (RLE) is a refractive surgery that removes the lens of the eye and replaces it with a silicone or plastic lens.

Phakic intraocular lens implants (PIOLs) are implanted at the edge of the cornea and behind the pupil of the eye, leaving the eye’s natural lens untouched. These lens implants function much the way contact lenses do. However, an eye surgeon will permanently implant phakic IOLs in your eyes.

Intracorneal ring segments (Intacs) are crescent-shaped plastic rings an eye surgeon will surgically place at the outer edge of the cornea to flatten it, changing how it focuses light rays onto the retina.
