 Conductive Keratoplasty
Until recently, if you were one of the millions of people with a refractive error, eyeglasses and contact lenses were the only options for correcting vision. But with the development of refractive surgery, some people with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (a ...
- Laser Surgery of the Eye
The word “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser is a concentrated beam of light, created when an electrical current passes through a special material. Used in eye surgery since the 1970s, the laser is popular for its unparalleled d ...
- Refractive Errors
Refractive errors occur when light does not focus properly on the retina because of the shape of the eye. The resulting image is blurred. Common refractive errors are myopia (nearsightedness), hyperopia (farsightedness), astigmatism (distorted vision), and presbyopia (aging eyes). &am ...
- Monovision for Presbyopia
Many people use reading glasses to correct presbyopia, the age-related loss of close-up focusing ability. They use their eyeglasses for reading and other close work, taking them off when looking at objects that are farther away, or they use bifocals for clear distance and near vision. Standard ...
- Cirugía Refractiva
La cirugía refractiva ayuda a reducir la dependencia de anteojos o lentes de contacto, cambiando de manera permanente la forma de la córnea (la capa transparente en frente del ojo). Cuando se trata la miopía, las técnicas de la cirugía refractiva reducen la cu ...
- LASIK por medio de Láser Femtosegundo
Hasta hace poco tiempo, si usted era uno de los millones de pacientes con errores refractivos, anteojos o lentes de contacto eran las únicas opciones para corregir la visión. Con el arrivo de la cirugía refractiva, algunos pacientes con miopía, hipermetropía o ...
- LASIK por medio de Láser Microkeratoma
Hasta hace poco tiempo, si usted era uno de los millones de pacientes con errores refractivos, anteojos o lentes de contacto eran las únicas opciones para corregir la visión. Con el arrivo de la cirugía refractiva, algunos pacientes con miopía, hipermetropía o ...
- Phakic Intraocular Lenses
Many people today choose to correct their refractive errors with techniques other than wearing eyeglasses or contact lenses. Surgeries such as laser-assisted in situ keratomileusis, or LASIK, can improve vision by permanently changing the shape of the cornea to redirect how light focuses on the ...
- Refractive Lens Exchange
Today, many people choose to correct their refractive errors with techniques other than wearing eyeglasses or contact lenses. Surgeries like laser-assisted in situ keratomileusis, or LASIK, improve vision by permanently changing the shape of the cornea to redirect how light is focused on the re ...
- Wavefront-Guided Laser Surgery
Laser-assisted in situ keratomileusis,or LASIK, is an outpatient surgical procedure that uses an excimer laser to reshape the eye’s cornea (the clear window in the front of the eye) to correct refractive errors. Refractive errors are problems with the way the eye focuses light, which caus ...
- Radial Keratotomy
Radial keratotomy (RK) is surgical procedure to reduce myopia (nearsightedness) by changing the curvature of the cornea. RK was invented in the 1930s and perfected in the late 1970s. People with myopia have difficulty with distance vision because the cornea has too much power and focuses light ...
- Phototherapeutic Keratectomy
The cornea is the smooth, clear window of the eye in front of the colored iris that helps bend light rays so they focus directly on the retina, the light-sensing layer of cells at the back of the eye. If the corneal surface is rough or cloudy, the rays of light do not focus properly on the reti ...
- Photorefractive Keratectomy
Until recently, if you were one of the millions of people with a refractive error (which means that light rays do not focus precisely on the retina, causing you to be nearsighted, farsighted, or astigmatic), eyeglasses and contact lenses were the only options for correcting vision. But with the ...
- LASIK with the Microkeratome
Until recently, if you were one of the millions of people with a refractive error, eyeglasses and contact lenses were the only options for correcting vision. But with the development of refractive surgery, some people with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (a ...
- LASIK With the Femtosecond Laser
Until recently, if you were one of the millions of people with a refractive error, eyeglasses and contact lenses were the only options for correcting vision. But with the development of refractive surgery, some people with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (a ...
- LASEK
Until recently, if you were one of the millions of people with a refractive error, eyeglasses and contact lenses were the only options for correcting vision. But with the development of refractive surgery, some people with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (a ...
- Intracorneal Rings
Intracorneal rings (ICRs) are plastic inserts placed in the cornea. The rings flatten the central cornea to correct low levels of myopia (nearsightedness). Unlike other refractive surgery procedures, ICR procedures can be reversed. When the inserts are removed, the cornea usually returns to its ...
- Epi-LASIK
Until recently, if you were one of the millions of people with a refractive error, eyeglasses and contact lenses were the only options for correcting vision. But with the development of refractive surgery, some people with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (a ...
- Ectasia
Ectasia is a condition that occurs when the cornea is so thin that intraocular pressure (IOP) leads to instability and bulging of the cornea. This causes blurring, myopia, and irregular astigmatism. During laser-assisted in situ keratomileusis (LASIK), the surgeon creates a flap in the outer l ...
