Lasik and Laser Surgery


  1. Corneal Flap Creation: In LASIK, a hinged flap is created on the cornea using a microkeratome (a mechanical device) or a femtosecond laser. This flap is then lifted to expose the underlying corneal tissue.

  2. Laser Reshaping: An excimer laser is used to precisely remove a predetermined amount of corneal tissue, reshaping the cornea to improve its focusing power. This step is customized based on the individual's refractive error.

  3. Flap Repositioning: After the laser treatment, the corneal flap is repositioned, where it begins to heal without the need for stitches.

Benefits of LASIK:

  1. Quick Recovery: Many people experience improved vision almost immediately after LASIK, and the recovery time is relatively fast compared to other types of refractive surgeries.

  2. Reduced Dependency on Glasses and Contact Lenses: LASIK can significantly reduce or eliminate the need for glasses or contact lenses for many individuals.

  3. High Precision: Excimer lasers used in LASIK surgery are known for their ability to remove tissue with extreme precision, allowing for accurate reshaping of the cornea.

  4. Predictable Outcomes: LASIK has a high success rate, and the outcomes are often predictable, especially in patients with low to moderate refractive errors.

Considerations and Risks:

  1. Not Suitable for Everyone: LASIK may not be suitable for individuals with certain eye conditions or health issues. A thorough pre-operative evaluation by an ophthalmologist is essential.

  2. Possible Complications: While LASIK is generally safe, as with any surgery, there are potential risks and complications, including dry eyes, glare, halos, and changes in vision.

  3. Stability of Refractive Error: LASIK is most effective for individuals with a stable refractive error; significant changes in prescription may affect the long-term success of the procedure.

  4. Age Considerations: LASIK is typically performed on adults whose eyes have fully matured. It is not recommended for children or teenagers.

Before undergoing LASIK or any refractive surgery, it's important to have a comprehensive eye examination and consultation with an experienced ophthalmologist to determine eligibility, discuss potential risks, and set realistic expectations for the outcome.
