LASEK, or Laser-Assisted Subepithelial Keratectomy, is a refractive eye surgery procedure commonly used to correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In Port Moresby, as in other locations, the process typically involves the following steps: 1. Initial consultation and evaluation: A comprehensive eye examination is conducted to determine the patient's eligibility for LASEK. This includes measuring the refractive error, assessing the health of the cornea, and considering other factors such as overall eye health and medical history. 2. Pre-operative preparation: The patient may be instructed to stop wearing contact lenses for a period of time before the surgery to allow the cornea to return to its natural shape. Medications may also be prescribed to prepare the eye. 3. Anesthesia: A local anesthetic is applied to the eye to numb it during the procedure. This helps ensure the patient's comfort. 4. Epithelial removal: A thin layer of the corneal epithelium is removed using a special instrument or a gentle laser. This exposes the underlying corneal stroma. 5. Laser ablation: The excimer laser is then used to precisely reshape the corneal stroma, correcting the refractive error. The laser emits short pulses of light that vaporize a small amount of corneal tissue. 6. Epithelial replacement: The removed epithelial layer is carefully replaced over the treated area. This promotes healing and helps protect the cornea. 7. Post-operative care: After the surgery, the patient is given specific instructions on how to care for the eye. This may include using eye drops, avoiding certain activities, and attending follow-up appointments to monitor the healing process. It's important to note that the success of LASEK depends on various factors, including the patient's eye condition, the surgeon's skill, and post-operative care. Patients should have a thorough discussion with their surgeon to understand the risks, benefits, and expectations of the procedure. Additionally, it's crucial to follow the surgeon's instructions for post-operative care to ensure optimal results. In Port Moresby, as elsewhere, it's advisable to choose a qualified and experienced plastic surgeon or ophthalmologist who specializes in refractive surgeries. They can provide personalized advice and guidance based on the individual's specific needs and circumstances.
