Lasik for Eyes

Lasik is a technique for reshaping cornial tissue so as to improve the vision of the concerned person. Lasik can be used to correct hyperopia, myopia and astigmatism. This technique produces a concentrated beam of cool, ultra violet (4V) light. It generates no heat and is gentle to tissue it improves the vision right away and becomes stable in 1-3 months.

Before laser treatment, patient is given medicine to relax him/her. Eye drops numb the eyes, a device is used to keep the eyes open. A slight pressure might be felt, but no pain, as the surgeon creates the flap. Laser treatment lasts for 10-90 seconds.

The flap (as said above) created is in the epithelium. The flap is folded back, remaining attached to the cornea. The surgeon uses a computer guided excimer laser to reshape the cornea. The flap is put back into place. The corneal tissue sticks to itself while it heals. Laser surgery is better for following patients:-

• Better for patients with thin cornea, previous glaucoma surgery, mild corneal scars or corneal problems.
• Possibly less post operative discomfort, haze, regression or corneal scarring.
• Possibly faster vision recovery as compared to other eye surgery.
Effects
• Mild to moderate pain after surgery.
• Longer vision recovery.
• May need to use eye drops for 3 months or longer.
Other eye implant procedures include implantation of special devices in the eyes to change their focusing ability. These implants are made from types of plastic similar to those used for contact lenses and cataract treatment.

Phakic Iols

Phakic intra ocular lenses (PIOLS) are artificial lenses that are placed inside the eye. Some are designed in a way that they are placed before the iris of the eye, while, others are placed behind it. The natural lens is not removed.

PIOLS are used to treat severe myopia or hyperopia. Before treatment patient is given local anesthesia and some medicine for relaxation. A “peripheral iridotomy” (drainage hole) is made in the “lris” to prevent fluid build up in the eye. An incision is then made in the cornea. The lens is inserted through the incision, after treatment, eye is bandaged. Vision starts to improve from the next day and becomes stable in 1-3 weeks.

Effects

• Implant can be removed if the desired result is not achieved.
• Can correct some extreme reparative problems.
• No loss of accommodation, since natural lens remains in place.
• No thinning of the cornea.
• Reduced risks of halos, glare or star bursts.

Intrasomal Corneal Ring Segments (ITACS)

In this case two flexible half-rings are inserted in the cornea. The right segments are placed in two tunnels, between the layers of corneal tissue. Cornea’s shape gets changed. The ring segments are invisible and cannot be felt. This treatment is used for mild to moderate myopia.

Effects

• No tissue is removed form the cornea.
• Implant can be removed/replaced, if the desired result is not achieved.
• No scarring of central cornea. Other eye-surgery procedures include clear lens extraction. Thermal procedure, refractive surgery etc.
• Before choosing any of the above surgery methods for correcting your vision problem, discuss with your doctor the type of eye-surgery, you should undergo.
