LASIK :
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.
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.
Flap Repositioning: After the laser treatment, the corneal flap is repositioned, where it begins to heal without the need for stitches.
Benefits of LASIK:
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.
Reduced Dependency on Glasses and Contact Lenses: LASIK can significantly reduce or eliminate the need for glasses or contact lenses for many individuals.
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.
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:
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.
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.
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.
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.
