Laser Thermal Keratoplasty (LTK) is a laser procedure made to shrink corneal tissue to correct farsightedness and the dependence on bifocals or reading glasses. This is done by reshaping the cornea, making it steeper, which increases the corneaβs focusing power.
It is done by applying two rings of eight spots around the optical zone of the eye. This causes shrinkage of the corneal collagen which increases the slope of the cornea.
On your procedure day, you will be treated in a special laser exam room. LTK does not require touching the cornea. Your eye will be numbed using drops, and an eyelid holder will be placed between the lids to prevent blinking during the procedure.
At the conclusion of your procedure, you will receive additional eye drops, along with instructions on how to use them, and your surgical eye may be shielded for protection.
The decision about whether or not to have laser thermal keratoplasty is very important, and the decision can only be made by you. The most important reason for having laser thermal keratoplasty ophthalmic surgery is to reduce the need for eyeglasses. Just remember, your ophthalmic professional cannot guarantee the requested results.
