LASIK
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a popular refractive eye surgery technique aimed at improving vision, often eliminating the need for glasses or contact lenses.
How it Works
During LASIK, first a laser is used to create a flap in front of the cornea, which is the clear front part of the eye. This flap is then lifted (like a hinge door) and another laser is used to reshape the cornea and thus change one’s eye prescription. The cornea's shape affects how light enters the eye and is crucial for clear vision. By precisely reshaping the cornea, LASIK aims to correct common vision issues such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
Nowadays, femtosecond laser is typically used to create the corneal flap in LASIK, replacing the traditional microkeratome blade. This has resulted in improved precision and safety of flap creation, reducing the risk of complications.
“Custom” wavefront guided LASIK measures the unique imperfections in an individual's eyes, providing a more personalized treatment plan for enhanced visual outcomes.
Who is the Candidate
Ideal candidates for LASIK are generally adults with stable vision prescriptions. They should be in good overall health, free from certain eye conditions or diseases. A thorough eye examination is conducted to determine if LASIK is a suitable option for an individual. People with thin or weak corneas, severe dry eyes, or certain medical conditions may not be ideal candidates.
Safety
LASIK is considered a very safe and effective procedure for many individuals. The significant majority of people experience great vision afterwards without complications. Like any surgical procedure, there are potential risks and side effects, such as dry eyes, glare, or halos around lights, but these are typically temporary. The safety of LASIK is continually enhanced by advancements in technology and the careful screening of candidates.
It's important to note that while LASIK is a widely accepted and successful procedure, individual experiences may vary. Consulting with an eye care professional is crucial to determine if LASIK is the right option for you and to discuss potential risks and benefits tailored to your unique circumstances and lifestyle choices.
