How does LASEK work in Australia

Understanding LASEK: A Professional Perspective

Laser-Assisted Sub-Epithelial Keratectomy (LASEK) is a refractive eye surgery technique that has gained popularity in Australia for its effectiveness in correcting vision problems such as myopia, hyperopia, and astigmatism. As a plastic surgeon with a focus on medical aesthetics, understanding the mechanisms and benefits of LASEK is crucial, especially when considering the holistic approach to patient care and enhancement.

Mechanism of LASEK

LASEK involves the use of a laser to reshape the cornea, the clear front part of the eye, to improve vision. Unlike other refractive surgeries such as LASIK, LASEK does not involve creating a flap in the corneal tissue. Instead, the outer layer of the cornea, known as the epithelium, is gently loosened and moved to the side. The laser is then used to ablate a small amount of underlying corneal tissue, altering its shape to correct refractive errors.

After the laser treatment, the epithelium is replaced over the treated area and a special contact lens is placed on the eye to protect the new surface as it heals. This lens is typically worn for several days, during which the epithelium regenerates and adheres back to the cornea.

Benefits of LASEK

One of the primary advantages of LASEK over other refractive surgeries is its reduced risk of complications such as dry eye and flap-related issues. Since LASEK does not involve cutting a flap, it is particularly suitable for patients with thin corneas or those who engage in contact sports, where the risk of eye injury is higher.

Additionally, LASEK offers a more conservative approach to corneal reshaping, which can be beneficial for patients who may not be ideal candidates for LASIK or PRK (Photorefractive Keratectomy). The recovery period for LASEK is generally longer than LASIK but shorter than PRK, with most patients achieving significant visual improvement within a few weeks.

Patient Selection and Pre-Operative Considerations

As a plastic surgeon, it is essential to carefully select patients who are suitable for LASEK. Comprehensive pre-operative assessments, including detailed eye examinations and evaluations of the patient's medical history, are crucial. Patients should be informed about the potential risks and benefits of the procedure, and realistic expectations should be set regarding the outcomes.

Factors such as age, refractive error stability, corneal thickness, and overall eye health are considered when determining the suitability of LASEK. Patients with certain medical conditions, such as autoimmune disorders or uncontrolled diabetes, may not be ideal candidates for the procedure.

Post-Operative Care and Follow-Up

Post-operative care is a critical aspect of LASEK, ensuring optimal healing and visual outcomes. Patients are typically prescribed eye drops to prevent infection and reduce inflammation. They are also advised to avoid rubbing their eyes and to protect them from exposure to dust and irritants.

Regular follow-up appointments are scheduled to monitor the healing process and assess the visual results. These appointments allow for early detection and management of any complications, ensuring the best possible outcome for the patient.

Conclusion

In conclusion, LASEK is a valuable refractive surgery option in Australia, offering a safe and effective alternative for patients with specific eye conditions and lifestyles. As a plastic surgeon, understanding the intricacies of LASEK and its benefits allows for informed decision-making and comprehensive patient care. By carefully selecting candidates, providing thorough pre-operative assessments, and ensuring meticulous post-operative care, LASEK can achieve excellent visual outcomes and enhance the quality of life for patients.
