Numerous eye disorders can be treated with laser eye surgery, which also enhances vision. Although LASIK surgery has grown in popularity, not everyone is a good candidate for this kind of treatment. This article will teach you about the many kinds of Eye Surgery , what to expect from laser eye surgery, and other information to have ready before making an appointment.
Laser eye surgery is a medical technique in which the surface of the eye is reshaped using a laser. Astigmatism, longsightedness, and shortsightedness are all improved or corrected with this. Overcoming presbyopia—the inability to see up close as we age—can also benefit from it. Even after receiving laser vision correction, some patients will still require glasses or contact lenses in order to have the best possible vision. Health insurance typically does not cover this costly operation.
Different strengths of focused waves are used in laser therapy to cut, shape, or even destroy specific body structures. With laser eye surgery , you may experience a shorter recovery period following the procedure and a lower chance of problems. Although most people associate laser eye surgery with vision correction, physicians may also utilize it to treat additional problems, such as:
The most well-known and often used laser corrective procedure to treat vision issues is LASIK eye surgery. As an alternative to spectacles or contact lenses, laser-assisted in situ keratomileusis (LASIK) may be used. A unique kind of cutting laser is utilized during LASIK surgery to alter the cornea's shape. The clear tissue at the front of the eye, formed like a dome, is called the cornea.
One kind of laser treatment is photorefractive keratectomy (PRK). This type of surgery treats optical errors-related vision issues with a laser. When light is not properly reflected, by your eye, you have a refractive error. Your ophthalmologist will use a laser to alter the shape of your cornea during PRK. This enhances the retina's ability to focus light beams. The three conditions that PRK treats are astigmatism, hyperopia, and myopia (nearsightedness).
Advanced Surface Ablation is referred to as ASA. Similar to PRK, this procedure reshapes the cornea using the Zeiss excimer laser Advanced Surface Treatment program. This type of PRK was granted FDA approval in 1995.
A procedure related to PRK is called LASEK, or Laser Assisted Sub-Epithelial Keratomileusis. The corneal epithelium is isolated from the underlying stromal layer, same as in PRK.
LBV, or laser blended vision, is a laser treatment used to improve reading and distance vision in people over 45. Monocular vision is employed, with the strong eye.
A novel method called SMILE, or Small Incision Lenticule Extraction, has been developed. It only uses one laser and has no blades. SMILE forms a lens-shaped disk of tissue inside the cornea by using an ultrafast laser. Because of its oval shape and ability to be removed, this tissue disc is referred to as a "lenticule." The patient's refractive error is taken into account when adjusting the lenticule's size and form. The lenticule is extracted by the laser eye surgeon via a 4-5 mm corneal incision. By flattening and reshaping the cornea, the removal corrects vision.
Insufficient correction: This could result from either over- or under-treating. For best results, you might require a second "enhancement" treatment.
Dry eyes: If you have dry eyes: you might need to have alternative therapy or use lubricating eye drops.
Infection: Although highly rare, antibiotic therapy may be required in the event of infection.
Superficial scarring: To address this, a second treatment is needed.
excessive corneal thinning: this might cause the cornea to bulge in a way that is comparable to keratoconus. As vision deteriorates, contact lenses or more surgeries become necessary.
Sensitive eyes: Some people claim to be more sensitive to glare, which can be hazardous when driving.
Hazy vision: The treatment may cause "shadows," or rings of unclear light, in your vision. Interestingly, unlike in the early days of laser vision correction, this is no longer regarded to be connected with large pupils.
Regression: is the idea that part of the prior refractive error—short- or long-sightedness—may reappear over time. To prevent the patient from needing spectacles, an augmentation operation can be required.
As a highly qualified physician, Dr. Sonalika has improved and brightened the lives of many individuals. Recognized for providing top-notch care, he is a highly recommended ophthalmologist in Pune. She specializes in low vision aid.
