Overview of PRK Lasek surgery
PRK (Photorefractive Keratectomy) Lasek is a laser eye surgery technique utilized to correct astigmatism, nearsightedness, and farsightedness. During the procedure, the corneal epithelium layer is carefully removed, and the excimer laser is applied to reshape the cornea. The epithelium layer is then repositioned. Towards the end of the surgery, a specialized lens is placed on the corneal surface to aid in the restoration of the epithelial layer. Within approximately 4 to 5 days, the epithelium layer fully regenerates, and optimal vision of the patient is achieved within 2 months.
The PRK procedure closely resembles LASIK, with the key distinction being that in Lasek, the epithelium layer is repositioned in the original place, while in PRK, it is temporarily separated from the cornea. Both procedures yield comparable results in terms of laser treatment and post-operative outcomes.
Questions and Answers about PRK Lasek Procedures
Frequently asked questions regarding pre- and post-operative procedures for Femto Lasik surgery:
- It is advised to take a bath the night before the procedure.
- Please avoid using any perfumes and makeup around the eyes.
- Please refrain using soft contact lenses for a minimum 3 days, and hard lenses for 3 weeks, leading up to the operation.
- Please inform your doctor of any drug known sensitivities to medications.
It is important to note that these actions are not painful, and your cooperation greatly influences achieving the desired outcome. Therefore, maintain composure, keep calm and pay attention the surgeon’s instructions throughout the procedure.
- Fixate on the blinking green light and avoid moving your eyes or head during the operation.
- The laser exposure lasts less than 20 seconds, depending on the specific type of laser being used. Therefore, refrain from moving your eyes during the time you hear the sound of the laser.
- Rest assured about your eyelids during the operation; because they will be gently held open, minimizing any discomfort. Avoid squeezing or frowning to prevent discomfort and pain.
- Keep your hands clear of the surgical area to prevent any potential contamination.
- Avoid rubbing your eyes.
- Refrain from wearing sunglasses in direct sunlight.
- Avoid exposure to eye-watering situations in the initial day post-surgery.
- Abstain from swimming for at least one month.
- In case of mild discomfort and pain, consider using pain relievers.
- It is safe to resume driving after a few days, exercising caution.
- Avoid applying pressure to your eyes during the initial weeks.
- Engaging in extended, close-range tasks, particularly under inadequate lighting conditions, may lead to diminished adaptation and, consequently, a slight regression of myopia, particularly in younger individuals.
- The laser is applied to the eye for 10 to 20 seconds for all prescription strengths. Taking into account pre-surgical preparations and the actual procedure conducted by the surgeon, the total time for each eye ranges from three to five minutes.
- Sure, provided the cornea exhibits sufficient thickness and the depth of the rim is appropriate, along with stable refractive errors, the unique conditions for this operation can be met.
- While all surgical methods are viable, if a swift recovery and expedited return to daily activities are prioritized, Smile surgery stands as the most efficient surgical approach.
- All devices used in Lasek procedures are advanced and show minimal variations.
- Not at all, Lasek is considered safe for natural childbirth.
- In Lasik, an incision is made on the corneal surface to create a flap, whereas in Lasek and PRK, this incision is not present. So instead in the latest one, only the epithelial layer is temporarily removed and subsequently regenerates within three to four days.
- Of course, under the appropriate eye conditions, this operation can be performed.
