is present from birth and can be corrected by glasses that have specially curved lenses to compensate for the unevenly shaped cornea.
is a condition where the curvature of the cornea is uneven, preventing light rays from focusing clearly on the retina, resulting in blurred vision.
Using premium multifocal and toric intraocular lenses built specifically for each patient, astigmatism
is reduced and the need for reading glasses eliminated.
They tested visual acuity of about 4,500 students and found the typical screening was best at detecting nearsightedness but likely missed many cases of farsightedness and astigmatism
, a condition in which the main symptom is blurred vision.
is a vision condition that occurs when surfaces of the eye, such as the cornea, are oval-shaped like an egg.
Most people have at least a small degree of astigmatism

The eximer laser is then used to ablate or reshape the interior of the cornea to correct myopia, astigmatism
, or farsightedness.
More than 6 million Americans cope every day with cataracts, the clouding of the eyes that gradually results in loss of vision, and astigmatism
, in which the eyes can become distorted, causing double vision.
The developer of a breakthrough approach to astigmatism
analysis sees a risk in the recent trend to link refractive lasers to corneal topography machines.
He uses surgical eye lasers, or excimer lasers, to treat nearsightedness and astigmatism
