LASIK is the most commonly performed refractive surgery procedure.The name  LASIK  is short for "laser-assisted in situ keratomileusis."
Is this a surgery commonly done? LASIK has advantages over other vision correction procedures, including a relative lack of pain afterward and the fact that good vision usually is achieved by the very next day.
An instrument called a microkeratome is used in LASIK eye surgery to create a thin, circular flap in the cornea. Another, newer way of making the flap is with a laser.
The surgeon folds the hinged flap back out of the way, then removes some corneal tissue underneath using an excimer laser. The excimer laser uses a cool ultraviolet light beam to precisely remove ("ablate") very tiny bits of tissue from the cornea to reshape it.

When the cornea is reshaped in the right way, it works better to focus light into the eye and onto the retina, providing clearer vision than before. The flap is then laid back in place, covering the area where the corneal tissue was removed.
Both nearsighted and farsighted people can benefit from the LASIK procedure. With nearsighted people, the goal is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. Excimer lasers also can correct astigmatism by smoothing an irregular cornea into a more normal shape.
With LASIK surgery, most people's vision improves right away, but some find that their vision gradually improves even more over the next few days or even weeks.


A cataract is a cloudiness of the eye's natural lens, which lies between the front and back areas of the eye.About half of the population has a cataract by age 65, and nearly everyone over 75 has at least one. But in rare cases, infants can have congenital cataracts. These are usually related to the mother having German measles, chickenpox, or another infectious disease during pregnancy, but sometimes they are inherited.
A cataract usually starts very small and practically unnoticeable but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle.

You need to continue to visit your eye doctor regularly so the cataract's progress is monitored. Some cataracts never really reach the stage where they should be removed.
If your cataract is interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it's time to discuss surgery with your doctor

How is a cataract removed?

A small incision is made into the eye. The surgeon will either remove the lens as is, or use ultrasound, a laser or surgical solution to break it up, and then remove it. The back membrane of the lens (called the posterior capsule) is left in place. Usually, a replacement lens (called an intraocular lens, or IOL) is inserted.
Occasionally, a doctor will perform intracapsular extraction; this is when both the lens and the membrane are removed, to ensure that the membrane itself won't eventually grow cloudy and interfere with vision. When the membrane becomes cloudy, or if any bits of remaining natural lens become cloudy, this is called a secondary cataract.The problem with intracapsular extraction is that the membrane is no longer there to receive a replacement lens.

YAG lasers are used in a later procedure to create a clear opening in the lens-containing membrane, if the membrane becomes cloudy in the months following the original cataract removal.

Nowadays, cataract patients who have intraocular lenses (IOLs) implanted during surgery may need reading glasses for close vision, but that's about it. In fact, with the newer multifocal and accommodating IOLs, even reading glasses are unnecessary.

People who don't receive IOLs wear contact lenses for distance vision, with reading glasses for close up. Or they may wear multifocal contact lenses for all distances. Rarely does anyone have to wear thick eyeglasses now.


A pterygium is a growth of scar tissue and blood vessels on the sun-exposed surface of the eye in response to ultraviolet damage from the environment. A pterygium often grows in a wing shape, which extends across the cornea towards the pupil. Pterygium most often occurs on the inner side of the pupil. The best treatment for pterygium is prevention. Wearing wrap around sunglasses when exposed to sun and wind will prevent a pterygium. Decongestants simply disguise the redness while the pterygium grows. A single dilated vessel can be treated with a laser but permanent removal of a pterygium requires surgery and this surgery can be performed by Dr. Miguel Castillo.


Eyelid surgery has many benefits, the obvious being an improvement in the overall appearance of the eyes. Eyelid surgery can be performed to remove excess skin that obscures the natural fold in the upper eyelids. It can also correct puffiness in the upper eyelids that cause the eyes to appear tired. For the lower eyelids, blepharoplasty can remove excess skin and correct fine wrinkles and lines. The bags that sometimes appear beneath the eyes can be removed, and the droopiness that sometimes occurs revealing the white portion of the eye beneath the iris can be corrected.
