What lasik eye surgery does?
LASIK (Laser-Assisted In Situ Keratomileusis) eye surgery is a type of refractive surgery that aims to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Here's an overview of what LASIK eye surgery does:
1. Reshaping the Cornea: LASIK surgery primarily involves reshaping the cornea, the clear outer layer of the eye that plays a crucial role in focusing light onto the retina. During the procedure, a thin flap is created in the cornea using a specialized cutting instrument.
2. Excimer Laser Treatment: Once the corneal flap is lifted, an excimer laser is used to precisely remove a small amount of corneal tissue. The laser reshapes the cornea to improve its focusing ability, allowing light to be accurately focused onto the retina. This step corrects vision errors such as nearsightedness, farsightedness, and astigmatism.
3. Flap Repositioning: After the corneal tissue is reshaped using the laser, the corneal flap is carefully repositioned and allowed to heal naturally. The flap typically adheres without the need for stitches, promoting a faster and more comfortable healing process.
4. Vision Correction: The reshaped cornea allows light to focus correctly onto the retina, leading to improved vision. Most people experience significant improvement in their vision within a few days or weeks after LASIK surgery.
5. Minimally Invasive: LASIK eye surgery is known for its minimally invasive nature. It is performed on an outpatient basis, meaning you can go home the same day as your procedure. Recovery time is relatively quick, with minimal discomfort reported by most patients.
6. Reduced Dependency on Glasses or Contact Lenses: LASIK aims to reduce or completely eliminate the need for eyeglasses or contact lenses. If you have been dependent on corrective lenses for clear vision, LASIK surgery may offer you freedom from such visual aids after successful treatment.
7. Long-Term Stability: LASIK surgery is known for its long-term stability. While individual results may vary, many patients enjoy the benefits of improved vision for many years following the procedure.
8. Suitability Evaluation: Before undergoing LASIK surgery, your eye doctor will thoroughly examine your eyes, assess the severity of your vision problem, and discuss your candidacy for the procedure. Not everyone may be a suitable candidate for LASIK due to various factors, such as certain eye conditions or corneal thickness.
It's important to understand that LASIK eye surgery does not guarantee perfect vision for everyone, and individual results may vary. Additionally, regular eye check-ups are recommended after LASIK to ensure the continued health of your eyes. If you are considering LASIK surgery, be sure to consult with an experienced and reputable eye care professional to discuss your specific needs and suitability for the procedure.
