Bringing Incredible Vision to Tarrant County for 28 years
LASIK has become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. In fact, most LASIK patients notice a significant improvement in their vision soon after surgery. LASIK removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism.
Kleiman | Evangelista Eye Center combines the precision of the Excimer laser with the flap technique that characterizes ALK procedures. First, no removal of the corneal surface tissue is necessary so postoperative pain is substantially reduced compared to PRK. Second, postoperative visual acuity is restored within a few days rather than weeks. Finally, there is less corneal scarring in the long-term, less change due to healing (regression) and greater stability of the correction.
LASIK improves the uncorrected vision for distance—one's visual capacity while not wearing corrective lenses—in most patients who have the procedure. Nearly all patients can expect to achieve 20/40 vision, which most states consider good enough to drive without having to wear contacts or glasses, and many can expect to achieve 20/20 vision or better. There are no guarantees, however, that you will have perfect vision after LASIK surgery. People who are most satisfied with the results of laser correction clearly understand the potential risks and complications, and possess realistic expectations of what their vision will be like after surgery.
To treat nearsightedness, the raised cornea is flattened by removing tissue from the center of the cornea. This moves the point of focus from in front of the retina to directly on the retina.
To treat farsightedness, the flat cornea is raised by removing tissue outside the central optical zone of the cornea. This moves the point of focus from behind the retina to directly on the retina.
To treat astigmatism, the cornea is made more spherical, more like a basketball than a football. This eliminates multiple focus points within the eye and creates one point of focus on the retina. Astigmatism can be treated at the same time as nearsightedness and farsightedness.
The effects of LASIK are permanent. The effects of LASIK do not wear off. But it is important to realize that a person's eye can still change internally. That is why many surgeons recommend having the procedure done after the major eye changes have occurred in one's life. For instance, LASIK is not recommended for children because their eyes change a great deal as they age, necessitating vision fine-tuning just a few years after surgery. If the procedure is performed after age 18, the chance of long-term stable correction is more likely. Even the eyes of patients over the age of 18 can still change, so we recommend an in-depth conversation with your surgeon about the changes your vision is undergoing. Reviewing these changes will help you make the decision whether to have the procedure now or wait until the changes have slowed down. Patients should also note that while results are usually stable, they can be modified by enhancement procedures performed after the initial one, if necessary.
You can resume most normal activities immediately after surgery. You should always wear safety glasses when playing contact sports, whether you have had surgery or not. If you do not routinely wear safety glasses, your surgeon may recommend wearing them for at least one month after LASIK. You will also need to avoid contact sports and swimming for several weeks. It is important to talk with your doctor about activity restrictions following your procedure, as every case is different.
LASIK is characterized by fast visual recovery. Most patients achieve good vision the day after surgery and find that their eyes feel fairly normal within 24 hours. Vision can continue to improve, however, and best vision can still take two to three months. Most patients who have LASIK do not wear glasses for their daily activities, but some patients over the age of 40 may still need to wear reading glasses because of presbyopia. Presbyopia, normal aging of the eye, occurs with or without LASIK and can cause some patients to need a minimal prescription for some activities such as night driving, even after LASIK.
Most people in their 40s or older will need reading glasses if their eyes are corrected for distance because our eyes' lens lose flexibility as we age. Some patients in this age group select monovision, similar to what is done with contact lenses. This option allows patients to use one of their eyes for distance and the other to see up close. Although monovision proves to be satisfactory for some patients, many are not comfortable with this arrangement. We will be happy to discuss every option with you to meet your individual needs.
