With astigmatism, the cornea (front surface of the eye) is shaped more like a football than a sphere, creating a distorted image on the retina.
A cataract is an opacity of the crystalline lens of the eye. This condition causes people to lose the clarity of their vision. Glare while driving at night is often one of the first symptoms of beginning cataracts. we treats cataracts with the latest surgical technique using no patch, no stitch surgery for most patients.
The cornea is the transparent outer layer of the eye. Its bulging curvature provides the major refraction of the eye. It is the cornea that is reshaped during laser vision correction.
Laser vision correction with the VISX Star S4 Trak laser with CustomVue software incorporates a three-dimensional, active tracking system to follow the minute movements of your eye during surgery. This ensures completely accurate application of the laser beam to your cornea.
Glaucoma is a disorder in which above normal intraocular pressure damages the optic nerve and causes loss of vision. Glaucoma can be determined during a routine eye exam and is treatable with drops, laser treatment and surgery.
In hyperopia, or farsightedness, vision is out of focus at all distances but can be cleared with effort. The condition is due to a flat corneal curvature or a shorter eye length and is often associated with eyestrain.
Laser Vision Correction
LASIK (Laser In-Situ Keratomileusis)
LASIK is a painless surgical procedure performed to correct nearsightedness, farsightedness, and astigmatism. During the procedure, a protective flap is first created in the surface layer of the cornea. The excimer laser is then used to sculpt the underlying corneal tissue. Finally the flap is replaced. The recovery period is usually very quick and most patients can return to work the next day.
Macular degeneration is an age related process whereby the retina of the eye degenerates. There are two types of macular degeneration: dry and wet.
Monovision refers to the correction of a patient's dominant eye for distance and non-dominant eye for near vision. This enables the presbyopic patient to see at near and at far for most tasks. We use monovision to reduce patient's need for glasses with LASIK and cataract surgery.
In the case of nearsightedness, vision is out of focus for distant objects. Myopia results when the cornea is too steep or the eye is too long, causing light to focus in front of the retina rather than directly on it.
An ophthalmologist is a medical doctor (eye M.D.) specializing in the eye and the visual system. He or she has completed medical school and at least four years of post-graduate training in diseases and surgery of the visual system. Ophthalmologists are licensed to examine eyes, treat eye diseases, and perform eye surgery.
Presbyopia is the age-induced inability to see objects at close range. This natural condition affects most people after the age of forty. Monovision is frequently used to help alleviate this problem along with Near Vision CK.
PRK (Photorefractive Keratectomy)
PRK is a surgical procedure in which an excimer laser is used to reshape the corneal surface. It differs from LASIK in that no protective flap is created in the outer corneal layer. Instead, the laser is applied directly to the surface of the cornea. As a result, PRK has a slower healing time and is, therefore, not the preferred method of laser vision correction.
