If your corneas are too thin, then you wont be able to have Lasik surgery. You also may not be able to receive Lasik surgery because of myopia, or nearsightedness.
It is harder to correct certain types of vision with Lasik surgery, meaning that you may not be able to receive the surgery. Because of this, as well as other reasons, there are other options that have been created and are available for you.
For those not wanting to consider surgery at all, contact lenses or eyeglasses are always available. Many contact lenses are being made to better fit eyes and not irritate as much.
They are being made more durable and resistant to outside dust and buildup, which helps with vision if another type of surgery doesnt want to be considered. While some may be more sensitive to contact lenses, it is always an option for those who have determined that they are not ready to receive a surgery.
However, if you don’t want to have eyeglasses or contacts and cant receive Lasik surgery, then it is possible to consider lens implants. This is best if you have nearsighted vision. This type of implant occurs through a small incision being made by the lens.
The lens, like a contact, is then inserted into your eye through this incision. This is then secured in your eye through the use of a special tool so that it will stay in the iris of the eye. The lens will then stay in the eye without you having to care for it. If needed, it can be taken out or replaced.
Lens implants aren’t as permanent as Lasik surgery, but are easier to care for than the eyeglasses or contacts. Unlike Lasik surgery, if something goes wrong during the lens implants, or if they are not being effective as expected, then they can simply be taken out or replaced.
Another type of surgery that is available is known as photorefractive keratectomy, also known as PRK. This is another type of refractive surgery that can be used for eyesight. It reshapes the cornea by taking out tissue from the outer surface. It does this by using an ultraviolet beam of light. This procedure does not take any more than a few minutes and is done only by the use of technology, as opposed to cutting that is offered in both the lens implants and Lasik surgery.
Another type of technological survey that can be used is laser thermal keratoplasty, also known as LTK. This procedure involves taking the cornea and removing parts of the outer part. In response, this shrinks the tissue around the cornea, allowing for better eyesight. This treatment is considered more temporary than the other procedures, as the tissue can easily grow back into place. However, if there is little loss of drawbacks that occur more easily in the other surgeries, such as a loss of eyesight or infection.
One more type of improved eyesight options is orthokeratology, or Ortho-K. This takes the RGP contact lenses or soft lenses and changes them in order to match the shape of the cornea, making them less irritable. The cornea can then temporarily reshape for better vision, causing the lenses to have to be worn less every day than usual. While this takes several months in order to change vision, and is not permanent, it is one option for those not wanting to go through a surgery to correct their vision.
For those who are nearsighted, a surgery known as corneal ring segments is available. These are plastic polymer pieces that are placed in the cornea, causing the cornea to reshape, similar to the Ortho-K. The cornea is then able to become flatter and can focus light easier than before. This procedure, while similar to the lens implants, is not permanent, and is still being tested for its effectiveness.
There are several different types of surgery in which you can receive, all which can help improve your vision either on a permanent or temporary basis. If you are not approved for Lasik surgery, there are several other options to consider trying and continuing to improve your vision.
