A surgical instrument with a metal oscillating blade to create the corneal flap in conventional LASIK.

Otherwise known as hyperopia, a vision condition in which distance objects can be seen more clearly than up-close objects. Farsightedness occurs if the cornea is too flat or if the eye is too short, causing images to focus behind the retina.

Otherwise known as myopia, a vision condition in which close objects are seen clearly, but objects farther away appear blurry. Nearsightedness occurs if the cornea is too steep, or the eye is elongated. As a result, images are focused in front of the retina and distance objects appear blurred. Nearsightedness is corrected by flattening the … Read more

A technology that creates a detailed, three-dimensional map of your eye. The image accurately and precisely measures the imperfections and irregularities in your eye. Wavefront technology is 25 times more accurate than the measurements typically taken during an eye exam, allowing us to correct imperfections that could never before be measured or corrected. Wavefront technology … Read more

Located at the back of the eyeball, the retina transmits the image to the brain through the optic nerve. The retina may be thought of as the photographic film of the eye.

Refractive errors are imperfections in the eye that cause blurred vision. The main refractive errors are nearsightedness, farsightedness, and astigmatism. Refractive errors can be corrected with glasses, contact lenses, or refractive surgery procedures such as LASIK or PRK.

A condition that normally occurs in people in their 40s and 50s. The crystalline lens inside your eye becomes less flexible as you age, which makes it difficult to focus on close objects. Presbyopia is a natural part of the aging process of the eye. It is not a disease, and it cannot be prevented. … Read more

Nearsightedness occurs if the cornea is too steep, or the eye is elongated. As a result, images are focused in front of the retina and distance objects appear blurred.

Nearsightedness. A person who is nearsighted can see objects up-close but distance objects appear blurred.

A treatment technique often prescribed for people with presbyopia. With blended monovision, one eye is corrected for distance and one eye is corrected for up-close vision. Blended monovision allows patients to see both distance and near without the need for glasses for most, if not all, activities. This type of monovision is easier for the … Read more

The part of the eye behind the pupil that, along with the cornea, helps to focus light on the retina. The lens of the eye works similar to a zoom lens of a camera and can change shape to help bring an image into focus.

Farsightedness. A person who is farsighted can see objects in the distance more clearly than objects up-close.

A class of laser used to create the corneal flap in 100% blade-free, All-Laser LASIK. LASIK is 100% blade-free.

Otherwise known as hyperopia, a vision condition in which distance objects can be seen more clearly than up-close objects. Farsightedness occurs if the cornea is too flat or if the eye is too short, causing images to focus behind the retina.

A class of cool-beam lasers used in refractive surgery to precisely and accurately reshape corneal tissue to correct refractive errors such as nearsightedness, farsightedness, and astigmatism.
