Laser Vision Correction
What is Laser Vision Correction?
Laser vision correction refers to a range of surgical procedures that uses Laser technology to reshape the cornea – a transparent front part of the eye, to improve vision. These procedures are primarily used to correct refractive errors such as Myopia (Nearsightedness), Hyperopia (Farsightedness), and Astigmatism.
Types of Laser Vision Correction
- LASIK (Laser Assisted in-Situ Keratomileusis)
- Overview: The most common type of laser vision correction.
- Procedure: Involves creating a thin flap in the cornea, lifting it to reshape the underlying corneal tissue with a laser, and then repositioning the flap.
- Recovery: Quick recovery with minimal discomfort.
- PRK (Photorefractive Keratectomy)
- Overview: An alternative for patients with thin cornea or where flap surgery is unfavourable.
- Procedure: It is flapless bladeless procedure where corneal moulding or reshaping is done completely by Laser.
- Recovery: Longer recovery time compared to LASIK, with a gradual improvement in vision.
- This will be 3rd type of LASER vision correction after PRK
Benefits of Laser Vision Correction
- Improved Vision: Most patients achieve 20/20 vision or better.
- Quick Recovery: Many patients experience improved vision within 24 hours.
- Long-lasting Results: Provides permanent correction of refractive errors.
- Reduced Dependency on Glasses/Contacts: Offers the freedom to engage in activities without the need for corrective lenses.
Risks and Considerations
- Side Effects: Common side effects include dry eyes, glare, halos, and fluctuating vision.
- Complications: hough rare, potential complications include infection, under-correction or over-correction, and corneal flap issues (in LASIK).
- Eligibility: Not everyone is a suitable candidate! Factors such as age, eye health, and the degree of refractive error are considered before taking a decision for Laser Vision Correction.
The Procedure: What to Expect
- Pre-operative Assessment
- Consultation: A thorough eye examination to determine suitability.
- Measurements: Precise measurements of the cornea and refractive power (glass number) to plan the procedure.
- Discussion: Explanation of the procedure, benefits, risks, and post-operative care.
- During the Procedure
- Preparation: Anesthetic drops are used to numb the eyes.
- Surgery: The laser reshapes the cornea in a matter of seconds.
- Completion: A short rest period before being allowed to go home.
Who is a Good Candidate?
Ideal candidates for laser vision correction:
- Age- Over 18 years old with stable vision.
- Stable glass prescription & number should be within the treatable range.
- Free from eye diseases and other health conditions that may affect healing.
Conclusion
Laser vision correction offers a life-changing opportunity for individuals struggling with glasses due to refractive errors. By understanding the types, benefits, risks, and what to expect from the procedure, patients can make an informed decision about whether laser vision correction is right for them or not! Always consult with a qualified ophthalmologist to discuss individual needs and ensure the best possible outcomes.
