The risks and possible complications include:
- malfunction of the microkeratome, the suction device, laser equipment, which can cause incorrect cutting of the flap of the cornea or poor positioning of the laser beam.
- infection or scarring of the cornea
- replace the flap of the cornea in the wrong place after surgery
- decreased vision, especially at night some people also complain of seeing “stars bursting” or halos around objects.
- dry eyes
- decreased vision after surgery, in some cases, glasses or contact lenses may not correct the problem completely
- persistent discomfort in the eye, blurred vision, or sensitivity to light
- overcorrection, which makes a person with problems for distance have trouble seeing up close or a person with problems for near have trouble seeing far away Read the rest of this entry »
Your first visit will be scheduled following the day after surgery. During this visit, your doctor will remove the eye patch, examine your cornea and check your vision. It may also prescribe antibiotic eye drops and artificial tears.
Your doctor will tell you when the time is right to return to drive, to makeup, to contact sports and using hot tubs or hot tubs. To help protect the operated eye, you probably need to wear a protective mask at night for four weeks.
Your doctor may ask you to return a second time to check your eye again a week after surgery. Depending on developments, you may need other tests in the next six months. Read the rest of this entry »
Your doctor will ask you to not wear makeup, creams and perfumes one or two days before surgery. You may not drive after LASIK surgery, so scheduled for a friend to drive you home.
The day of surgery, your doctor will give you a mild sedative to help you relax. You will enter the operating room and lie in a recliner. The doctor cleaned the area around your eyes with an antiseptic solution. Then he placed anesthetic drops in his eyes that he does not feel pain or discomfort during the procedure. Will insert an instrument called a speculum into your eye lid to keep your eyelids open and the doctor will use a special ink for marking on your cornea the area to operate.
Then he placed a suction device like a ring in front of the eye in place to keep the cornea during the operation. This suction ring will cause a sensation of pressure but not pain. Finally, he used a sensitive instrument called a microkeratome to cut a tiny flap of tissue in front of your cornea. You will not see or feel the microkeratome cut your cornea.

Once you have chosen to view LASIK surgery, your doctor will schedule an assessment visit before surgery. If you wear contact lenses, you should not use glasses and placed a few weeks before this evaluation. This will allow your cornea to return to its normal form.
During preoperative evaluation, your doctor will evaluate your medical history and past operations at the hearing. To confirm that your vision is stable, it may ask to see the previous recipes, so bring them with you when you visit your doctor. Also, make a list of medications you take, including nonprescription products and herbal remedies. Read the rest of this entry »
LASIK can be used for the treatment of vision problems as follows:
- for distance vision problems (myopia)
- trouble seeing close (farsightedness)
- astigmatism, in which the blurring is caused by a deformation of the cornea
If you have one of the following vision problems, your doctor can tell you more about LASIK and tell you if this technique is appropriate for you.
LASIK treatment may not be an option if: Read the rest of this entry »
LASIK is a new method of eye surgery that uses a laser to reshape the cornea. LASIK stands for “laser in situ keratomileusis.”
The cornea is the “window” round transparent tissue that permits passage of light through the eye. To reshape the cornea, the surgeon adjusts the focus of light on the retina (the layer in the back of the eye responsible for vision). As a result, often improves vision in people who have trouble seeing at near, far or other vision problems.
During LASIK surgery, the eye surgeon (ophthalmologist) first cuts a small flap of tissue from the front of the cornea with an instrument called a microkeratome. Once the flap is removed from that area, using a laser to reshape the underlying protein fibers (collagen) of the cornea. Before surgery, is taken from the cornea, an eye doctor (ophthalmologist). After performing the procedure, the corneal flap is put back in place. As the cornea heals quickly, many people who have been operated with LASIK seen dramatic improvements in vision almost immediately. Read the rest of this entry »
Thanks to recent technological advances, a group of scientists is working to develop contact lens whose main purpose is not to allow people to see better, but to quell their pain after laser surgery eyes. In this article we tell you more details on this promising research.
Hand in hand with advances in nanotechnology called (which is dedicated to the control and manipulation of matter on a tiny scale, the level of atoms and molecules), a group of scientists began looking for a new way to ease the pain people who undergo laser surgery on the eyes, such as Photorefractive Keratotomy (PRK) and Lasik procedure.
All surgeries eye laser uses a cool ultraviolet light beam and pulse to correct vision. It is used when, for example, people have nearsightedness, farsightedness or astigmatism mild or moderate in order to improve vision and reduce dependence on one person to wear glasses or contact lenses.
