Understanding What to Expect With Refractive Surgery

 

Refractive surgery, also referred to as LASIK, is non-invasive eye surgery usually performed to improve vision, reduce dependency on eyeglasses or contacts and improve the visual quality of a patient. This can even include several methods of corrective cosmetic surgery, including lens implantation, surgical reshaping of the cornea or lens, or even lens replacement. While a patient is still required to have prescription eyeglasses and contacts if he wants to have good eyesight without the need of glasses, these are no longer mandatory for a lot of patients who can afford the procedure.Chick here for more details about chirurgia refrattiva

Refractive surgery, as with any type of eye surgery, involves risks and complications. Although the dangers are minimal compared to other procedures, it can still lead to discomfort and eye injury if not properly handled. As with any type of surgery, some risks are more common in patients with refractive surgery than in those without, including corneal scarring, choroidal damage, or the loss of vision. There are also a few risks that can be minimized by following a few simple precautions before, during, and after the procedure.

Before undergoing a refractive surgery, the patient and his eye surgeon must decide if a bifocal or progressive lens is appropriate. A bifocal lens will provide a better choice of reading material, allowing people with nearsightedness and farsightedness to see clearly. Progressive lenses, on the other hand, are suitable for people with hyperopic and astigmatism, making it easier to read. A patient who is having refractive surgery for vision correction can choose either a bifocal or progressive lens depending on the current condition of their eyes. In this case, the patient should consult his eye surgeon to discuss his options. Both options require an operation for either reshaping and tiling of the corneal surface.

The type of corneal flap that the patient will receive for the procedure must also be decided on by the eye surgeon. Flaps are used to correct several different issues with the vision of patients having refractive surgery. It can either be an open flap, which allows the surgeon to be able to insert a thin plastic lens that provides a clearer image to the patient, or a closed flap, where the surgeon cannot insert any additional plastic lenses. If a patient is going through refractive surgery for vision correction, he must also opt for a flap that is made out of an all-optical material such as silicone gel, silicone membrane or polylactide gel. and is made from the exact size, shape and design of his corneal flap. It must also have a high degree of thickness and should fit perfectly over the corneal surface. After surgery, the patient should wear disposable polystyrene goggles to protect his eyes and avoid irritation caused by the incision.

An eye surgeon will also need to perform a preoperative checkup before the operation, to ensure that the patient's eye is ready to undergo the procedure. This checkup will involve checking for signs of infection, eye allergies and any underlying diseases that may affect the vision of the patient prior to the procedure. Once the preoperative checklist is completed, the eye surgeon will move to prepare the patient and monitor his vision after the procedure. While the patient is asleep and still wearing his goggles, the surgeon will perform the procedure on the affected area of the eyes.

It is important to be alert and aware of the instructions given to the patient, even when a patient is asleep. If there are any changes in his vision that make his task of watching TV difficult or even cause him difficulty while driving, the doctor will alert him immediately to tell the doctor. so that corrective measures can be taken right away to correct the situation.
